+<h3>How to Port</h3>
+
+<h4>Basic considerations</h4>
+<p>The FatFs module is assuming following conditions on portability.</p>
+<ul>
+<li>ANSI C<br>
+The FatFs module is a middleware written in ANSI C (C89). There is no platform dependence, so long as the compiler is in compliance with ANSI C.</li>
+<li>Size of integer types<br>
+The FatFs module assumes that size of char/short/long are 8/16/32 bit and int is 16 or 32 bit. These correspondence are defined in <tt>integer.h</tt>. This will not be a problem on most compilers. When any conflict with existing definitions is occured, you must resolve it with care.</li>
+</ul>
+
+<h4>System organizations</h4>
+<p>The dependency diagram shown below is a typical configuration of the embedded system with FatFs module.</p>
+<p><img src="../img/modules.png" width="580" height="280" alt="dependency diagram"></p>
+<p>(a) If a working disk module with FatFs API is provided, no additional function is needed. (b) To attach existing disk drivers with different API, glue functions are needed to translate the APIs between FatFs and the drivers.</p>
+<p><img src="../img/funcs.png" width="680" height="430" alt="functional diagram"></p>
+
+<h4>Which function is required?</h4>
+<p>You need to provide only low level disk I/O functions that required by FatFs module and nothing else. If a working disk module for the target is already existing, you need to write only glue functions to attach it to the FatFs module. If not, you need to port any other disk module or write it from scratch. Most of defined functions are not that always required. For example, disk write function is not required in read-only configuration. Following table shows which function is required depends on configuration options.</p>

+<h3>Long File Name</h3>
+<p>FatFs module supports LFN (long file name). The two different file names, SFN (short file name) and LFN, of a file is transparent on the API except for <tt>f_readdir()</tt> function. The LFN feature is disabled by default. To enable it, set <tt>_USE_LFN</tt> to 1, 2 or 3, and add <tt>option/unicode.c</tt> to the project. The LFN feature requiers a certain working buffer in addition. The buffer size can be configured by <tt>_MAX_LFN</tt> according to the available memory. The length of an LFN will reach up to 255 characters, so that the <tt>_MAX_LFN</tt> should be set to 255 for full featured LFN operation. If the size of working buffer is insufficient for the input file name, the file function fails with <tt>FR_INVALID_NAME</tt>. When enable the LFN feature with re-entrant configuration, <tt>_USE_LFN</tt> must be set to 2 or 3. In this case, the file function allocates the working buffer on the stack or heap. The working buffer occupies <tt>(_MAX_LFN + 1) * 2</tt> bytes.</p>
+<table class="lst2 rset">
+<caption>LFN cfg on ARM7TDMI</caption>
+<tr><th>Code page</th><th>Program size</th></tr>

+<tr><td>950(Big5)</td><td>+111K</td></tr>
+</table>
+<p>When the LFN feature is enabled, the module size will be increased depends on the selected code page. Right table shows how many bytes increased when LFN feature is enabled with some code pages. Especially, in the CJK region, tens of thousands of characters are being used. Unfortunately, it requires a huge OEM-Unicode bidirectional conversion table and the module size will be drastically increased that shown in the table. As the result, the FatFs with LFN feature with those code pages will not able to be implemented to most 8-bit microcontrollers.</p>
+<p>Note that the LFN feature on the FAT file system is a patent of Microsoft Corporation. This is not the case on FAT32 but most FAT32 drivers come with the LFN feature. FatFs can swich the LFN feature off by configuration option. When enable LFN feature on the commercial products, a license from Microsoft may be required depends on the final destination.</p>
+</div>
+
+<div class="para" id="unicode">
+<h3>Unicode API</h3>
+<p>By default, FatFs uses ANSI/OEM code set on the API under LFN configuration. FatFs can also switch the character encoding to Unicode on the API by <tt>_LFN_UNICODE</tt> option. This means that the FatFs supports the True-LFN feature. For more information, refer to the description in the <a href="filename.html">file name</a>.</p>
+</div>
+
+<div class="para" id="reentrant">
+<h3>Re-entrancy</h3>
+<p>The file operations to the different volume is always re-entrant and can work simultaneously. The file operations to the same volume is not re-entrant but it can also be configured to thread-safe by <tt>_FS_REENTRANT</tt> option. In this case, also the OS dependent synchronization object control functions, <tt>ff_cre_syncobj(), ff_del_syncobj(), ff_req_grant() and ff_rel_grant()</tt> must be added to the project. There are some examples in the <tt>option/syscall.c</tt>.</p>
+<p>When a file function is called while the volume is in use by any other task, the file function is suspended until that task leaves the file function. If wait time exceeded a period defined by <tt>_TIMEOUT</tt>, the file function will abort with <tt>FR_TIMEOUT</tt>. The timeout feature might not be supported by some RTOS.</p>
+<p>There is an exception for <tt>f_mount(), f_mkfs(), f_fdisk()</tt> function. These functions are not re-entrant to the same volume or corresponding physical drive. When use these functions, all other tasks must unmount the volume and avoid to access the volume.</p>
+<p>Note that this section describes on the re-entrancy of the FatFs module itself but also the low level disk I/O layer will need to be re-entrant.</p>
+</div>
+
+<div class="para" id="dup">
+<h3>Duplicated File Access</h3>
+<p>FatFs module does not support the read/write collision control of duplicated open to a file. The duplicated open is permitted only when each of open method to a file is read mode. The duplicated open with one or more write mode to a file is always prohibited, and also open file must not be renamed and deleted. A violation of these rules can cause data colluption.</p>
+<p>The file lock control can also be available by <tt>_FS_LOCK</tt> option. The value defines the number of open objects to manage simultaneously. In this case, if any open, rename or remove that violating the file shareing rule that described above is attempted, the file function will fail with <tt>FR_LOCKED</tt>. If number of open objects, files and sub-directories, gets larger than <tt>_FS_LOCK</tt>, the <tt>f_open(), f_optndir()</tt> function will fail with <tt>FR_TOO_MANY_OPEN_FILES</tt>.</p>
+</div>
+
+<div class="para" id="fs1">
+<h3>Performance Effective File Access</h3>
+<p>For good read/write throughput on the small embedded systems with limited size of memory, application programmer should consider what process is done in the FatFs module. The file data on the volume is transferred in following sequence by <tt>f_read()</tt> function.</p>
+<p>Figure 1. Sector misaligned read (short)<br>
+<img src="../img/f1.png" width="490" height="110" alt="">
+</p>
+<p>Figure 2. Sector misaligned read (long)<br>
+<img src="../img/f2.png" width="490" height="140" alt="">
+</p>
+<p>Figure 3. Fully sector aligned read<br>
+<img src="../img/f3.png" width="490" height="119" alt="">
+</p>
+<p>The file I/O buffer is a sector buffer to read/write a partial data on the sector. The sector buffer is either file private sector buffer on each file object or shared sector buffer in the file system object. The buffer configuration option <tt>_FS_TINY</tt> determins which sector buffer is used for the file data transfer. When tiny buffer (1) is selected, data memory consumption is reduced 512 bytes each file object. In this case, FatFs module uses only a sector buffer in the file system object for file data transfer and FAT/directory access. The disadvantage of the tiny buffer configuration is: the FAT data cached in the sector buffer will be lost by file data transfer and it must be reloaded at every cluster boundary. However it will be suitable for most application from view point of the decent performance and low memory comsumption.</p>
+<p>Figure 1 shows that a partial sector, sector misaligned part of the file, is transferred via the file I/O buffer. At long data transfer shown in Figure 2, middle of transfer data that covers one or more sector is transferred to the application buffer directly. Figure 3 shows that the case of entier transfer data is aligned to the sector boundary. In this case, file I/O buffer is not used. On the direct transfer, the maximum extent of sectors are read with <tt>disk_read()</tt> function at a time but the multiple sector transfer is divided at cluster boundary even if it is contiguous.</p>
+<p>Therefore taking effort to sector aligned read/write accesss eliminates buffered data transfer and the read/write performance will be improved. Besides the effect, cached FAT data will not be flushed by file data transfer at the tiny configuration, so that it can achieve same performance as non-tiny configuration with small memory footprint.</p>

+<h3>Considerations on Flash Memory Media</h3>
+<p>To maximize the write performance of flash memory media, such as SDC, CFC and U Disk, it must be controlled in consideration of its characteristitcs.</p>
+<h4>Using Mutiple-Sector Write</h4>
+<div class="rset">
+Figure 6. Comparison between Multiple/Single Sector Write<br>
+<img src="../img/f6.png" width="630" height="148" alt="fig.6">
+</div>
+<p>The write throughput of the flash memory media becomes the worst at single sector write transaction. The write throughput increases as the number of sectors per a write transaction. This effect more appers at faster interface speed and the performance ratio often becomes grater than ten. <a href="../img/rwtest2.png">This graph</a> is clearly explaining how fast is multiple block write (W:16K, 32 sectors) than single block write (W:100, 1 sector), and also larger card tends to be slow at single block write. The number of write transactions also affects the life time of the flash memory media. Therefore the application program should write the data in large block as possible. The ideal write chunk size and alighment is size of sector, and size of cluster is the best. Of course all layers between the application and the storage device must have consideration on multiple sector write, however most of open-source disk drivers lack it. Do not split a multiple sector write request into single sector write transactions or the write throughput gets poor. Note that FatFs module and its sample disk drivers supprt multiple sector read/write feature. </p>
+<h4>Forcing Memory Erase</h4>
+<p>When remove a file with <tt>f_remove()</tt> function, the data clusters occupied by the file are marked 'free' on the FAT. But the data sectors containing the file data are not that applied any process, so that the file data left occupies a part of the flash memory array as 'live block'. If the file data is forced erased on removing the file, those data blocks will be turned in to the free block pool. This may skip internal block erase operation to the data block on next write operation. As the result the write performance might be improved. FatFs can manage this feature by setting <tt>_USE_ERASE</tt> to 1. Note that this is an expectation of internal process of the flash memory storage and not that always effective. Also <tt>f_remove()</tt> function will take a time when remove a large file. Most applications will not need this feature.</p>

+<h3>Critical Section</h3>
+<p>If a write operation to the FAT volume is interrupted due to any accidental failure, such as sudden blackout, incorrect disk removal and unrecoverable disk error, the FAT structure on the volume can be broken. Following images shows the critical section of the FatFs module.</p>
+<div class="lset">

+<br class="clr">
+<p>An interruption in the red section can cause a cross link; as a result, the object being changed can be lost. If an interruption in the yellow section is occured, there is one or more possibility listed below.</p>
+<ul>
+<li>The file data being rewrited is collapsed.</li>
+<li>The file being appended returns initial state.</li>
+<li>The file created as new is gone.</li>
+<li>The file created as new or overwritten remains but no content.</li>
+<li>Efficiency of disk use gets worse due to lost clusters.</li>
+</ul>
+<p>Each case does not affect the files that not opened in write mode. To minimize risk of data loss, the critical section can be minimized by minimizing the time that file is opened in write mode or using <tt>f_sync()</tt> function as shown in Figure 5.</p>

+<h4>Description</h4>
+<p>The FatFs module requires only five device independent commands described below.</p>
+<table class="lst">
+<caption>Standard ioctl command used by FatFs</caption>
+<tr><th>Command</th><th>Description</th></tr>
+<tr><td>CTRL_SYNC</td><td>Make sure that the device has finished pending write process. If the disk I/O module has a write back cache, the dirty buffers must be written back to the media immediately. Nothing to do for this command if each write operation to the media is completed within the <tt>disk_write()</tt> function. Required at <tt>_FS_READONLY == 0</tt>.</td></tr>
+<tr><td>GET_SECTOR_COUNT</td><td>Returns number of available sectors on the drive into the <tt>DWORD</tt> variable pointed by <tt class="arg">buff</tt>. This command is used by only <tt>f_mkfs()</tt> and <tt>f_fdisk()</tt> function to determine the volume/partition size to be created. Required at <tt>_USE_MKFS == 1</tt> or <tt>_MULTI_PARTITION == 1</tt>.</td></tr>
+<tr><td>GET_SECTOR_SIZE</td><td>Returns sector size of the media into the <tt>WORD</tt> variable pointed by <tt class="arg">buff</tt>. Valid return values of this command are 512, 1024, 2048 or 4096. This command is required at variable sector size configuration, <tt>_MAX_SS &gt; _MIN_SS</tt>. Never used at fixed sector size configuration, <tt>_MAX_SS == _MIN_SS</tt>, and it must work at that sector size.</td></tr>
+<tr><td>GET_BLOCK_SIZE</td><td>Returns erase block size of the flash memory in unit of sector into the <tt>DWORD</tt> variable pointed by <tt class="arg">buff</tt>. The allowable value is from 1 to 32768 in power of 2. Return 1 if the erase block size is unknown or disk media. This command is used by only <tt>f_mkfs()</tt> function and it attempts to align data area to the erase block boundary. Required at <tt>_USE_MKFS == 1</tt>.</td></tr>
+<tr><td>CTRL_ERASE_SECTOR</td><td>Informs device that the data on the block of sectors specified by a <tt>DWORD</tt> array {&lt;start sector&gt;, &lt;end sector&gt;} pointed by <tt class="arg">buff</tt> is no longer needed and may be erased. The device would force erased the memory block. This is a command similar to Trim command of ATA device. When this feature is not supported or not a flash memory media, nothing to do for this command. The FatFs does not check the result code and the file function is not affected even if the sectors ware not erased well. This command is called on removing a cluster chain and <tt>f_mkfs()</tt> function. Required at <tt>_USE_ERASE == 1</tt>.</td></tr>
+</table>
+
+<p>FatFs never uses any device dependent command and user defined command. Following table shows an example of non-standard commands usable for some applications.</p>
+<table class="lst">
+<caption>Example of optional ioctl command</caption>
+<tr><th>Command</th><th>Description</th></tr>
+<tr><td>CTRL_FORMAT</td><td>Create a physical format on the media. If <tt class="arg">buff</tt> is not null, it is pointer to the call-back function for progress notification.</td></tr>
+<tr><td>CTRL_POWER_IDLE</td><td>Put the device idle state. <tt>STA_NOINIT</tt> in status flag may not be set if the device would go active state by generic read/write function.</td></tr>
+<tr><td>CTRL_POWER_OFF</td><td>Put the device off state. Shut-down the power to the device and deinitialize the device interface if needed. <tt>STA_NOINIT</tt> in status flag must be set. The device goes active state by <tt>disk_initialize()</tt> function.</td></tr>
+<tr><td>CTRL_LOCK</td><td>Lock media eject mechanism.</td></tr>
+<tr><td>CTRL_UNLOCK</td><td>Unlock media eject mechanism.</td></tr>
+<tr><td>CTRL_EJECT</td><td>Eject media cartridge. <tt>STA_NOINIT</tt> and <tt>STA_NODISK</tt> in status flag are set after the function succeeded.</td></tr>
+<tr><td>MMC_GET_TYPE</td><td>Get card type. The type flags, bit0:MMCv3, bit1:SDv1, bit2:SDv2+ and bit3:LBA, is stored to a BYTE variable pointed by <tt class="arg">buff</tt>. (MMC/SDC specific command)</td></tr>
+<tr><td>MMC_GET_CSD</td><td>Get CSD register into a 16-byte buffer pointed by <tt class="arg">buff</tt>. (MMC/SDC specific command)</td></tr>
+<tr><td>MMC_GET_CID</td><td>Get CID register into a 16-byte buffer pointed by <tt class="arg">buff</tt>. (MMC/SDC specific command)</td></tr>
+<tr><td>MMC_GET_OCR</td><td>Get OCR register into a 4-byte buffer pointed by <tt class="arg">buff</tt>. (MMC/SDC specific command)</td></tr>
+<tr><td>MMC_GET_SDSTAT</td><td>Get SDSTATUS register into a 64-byte buffer pointed by <tt class="arg">buff</tt>. (SDC specific command)</td></tr>
+<tr><td>ATA_GET_REV</td><td>Get the revision string into a 16-byte buffer pointed by <tt class="arg">buff</tt>. (ATA/CFC specific command)</td></tr>
+<tr><td>ATA_GET_MODEL</td><td>Get the model string into a 40-byte buffer pointed by <tt class="arg">buff</tt>. (ATA/CFC specific command)</td></tr>
+<tr><td>ATA_GET_SN</td><td>Get the serial number string into a 20-byte buffer pointed by <tt class="arg">buff</tt>. (ATA/CFC specific command)</td></tr>

+<h4>Description</h4>
+<p>The memory address specified by <tt class="arg">buff</tt> is not that always aligned to word boundary because the type of argument is defined as <tt>BYTE*</tt>. The misaligned read/write request can occure at <a href="appnote.html#fs1">direct transfer</a>. If the bus architecture, especially DMA controller, does not allow misaligned memory access, it should be solved in this function. There are some workarounds described below to avoid this issue.</p>
+<ul>
+<li>Convert word transfer to byte transfer in this function. - Recommended.</li>
+<li>For <tt>f_read()</tt>, avoid long read request that includes a whole of sector. - Direct transfer will never occure.</li>
+<li>For <tt>f_read(fp, buff, btr, &amp;br)</tt>, make sure that <tt>(((UINT)buff &amp; 3) == (f_tell(fp) &amp; 3))</tt> is true. - Word aligned direct transfer is guaranteed.</li>
+</ul>
+<p>Generally, a multiple sector transfer request must not be split into single sector transactions to the storage device, or you will not get good read throughput.</p>

+<h4>Description</h4>
+<p>The <tt>f_fdisk()</tt> function creates a partition table into the MBR of the physical drive. The partitioning rule is in generic FDISK format, so that it can create upto four primary partitions. Logical volumes in the extended partition is not supported. The <tt class="arg">part[]</tt> with four items specifies how to divide the physical drive. The first item specifies the size of first primary partition and fourth item specifies the fourth primary partition. If the value is less than or equal to 100, it specifies percentage of the partition in the entire disk space. If it is larger than 100, it specifies the partition size in unit of sector.</p>

+<title>FatFs - Path Names</title>
+</head>
+
+<body>
+<h1>Path Names</h1>
+
+<div class="para" id="nam">
+<h3>Format of the path names</h3>
+<p>The format of path name on the FatFs module is similer to the filename specs of DOS/Windos as follows:</p>
+<pre>"[<em>drive</em>:][/]<em>directory</em>/<em>file</em>"</pre>
+<p>The FatFs module supports long file name (LFN) and 8.3 format file name (SFN). The LFN can be used when LFN feature is enabled (<tt>_USE_LFN &gt; 0</tt>). The sub directories are separated with a \ or / in the same way as DOS/Windows API. Duplicated separators are skipped and ignored. Only a difference is that the logical drive is specified in a numeral with a colon. When drive number is omitted, the drive number is assumed as <em>default drive</em> (drive 0 or current drive).</p>
+<p>Control characters (<tt>'\0'</tt> to <tt>'\x1F'</tt>) are recognized as end of the path name. Leading/embedded spaces in the path name are valid as a part of the name at LFN configuration but they are recognized as end of the path name at non-LFN configuration. Trailing spaces and dots are ignored.</p>
+<p>In default configuration (<tt>_FS_RPATH == 0</tt>), it does not have a concept of current directory like OS oriented file system. All objects on the volume are always specified in full path name that follows from the root directory. Dot directory names are not allowed. Heading separator is ignored and it can be exist or omitted. The default drive is fixed to drive 0.</p>
+<p>When relative path feature is enabled (<tt>_FS_RPATH == 1</tt>), specified path is followed from the root directory if a heading separator is exist. If not, it is followed from the current directory of the drive set with <a href="chdir.html">f_chdir</a> function. Dot names are also allowed for the path name. The default drive is the current drive set with <a href="chdrive.html">f_chdrive</a> function.</p>
+<table class="lst2">
+<tr><td>Path name</td><td>_FS_RPATH == 0</td><td>_FS_RPATH == 1</td></tr>
+<tr class="lst3"><td>file.txt</td><td>A file in the root directory of the drive 0</td><td>A file in the current directory of the current drive</td></tr>
+<tr><td>/file.txt</td><td>A file in the root directory of the drive 0</td><td>A file in the root directory of the current drive</td></tr>
+<tr><td></td><td>The root directory of the drive 0</td><td>The current directory of the current drive</td></tr>
+<tr><td>/</td><td>The root directory of the drive 0</td><td>The root directory of the current drive</td></tr>
+<tr><td>2:</td><td>The root directory of the drive 2</td><td>The current directory of the drive 2</td></tr>
+<tr><td>2:/</td><td>The root directory of the drive 2</td><td>The root directory of the drive 2</td></tr>
+<tr><td>2:file.txt</td><td>A file in the root directory of the drive 2</td><td>A file in the current directory of the drive 2</td></tr>
+<tr><td>../file.txt</td><td>Invalid name</td><td>A file in the parent directory</td></tr>
+<tr><td>.</td><td>Invalid name</td><td>This directory</td></tr>
+<tr><td>..</td><td>Invalid name</td><td>Parent directory of the current directory</td></tr>
+<tr><td>dir1/..</td><td>Invalid name</td><td>The current directory</td></tr>
+<tr><td>/..</td><td>Invalid name</td><td>The root directory (sticks the top level)</td></tr>
+</table>
+<p>When option <tt>_STR_VOLUME_ID</tt> is specified, also pre-defined strings can be used as drive identifier in the path name instead of a numeral.</p>
+</div>
+
+<p><br></p>
+<div class="para" id="uni">
+<h3>Unicode API</h3>
+<p>The path names are input/output in either ANSI/OEM code (SBCS/DBCS) or Unicode depends on the configuration options. The type of arguments which specify the file names are defined as <tt>TCHAR</tt>. It is an alias of <tt>char</tt> in default. The code set used to the file name string is ANSI/OEM specifid by <tt>_CODE_PAGE</tt>. When <tt>_LFN_UNICODE</tt> is set to 1, the type of the <tt>TCHAR</tt> is switched to <tt>WCHAR</tt> to support Unicode (UTF-16 encoding). In this case, the LFN feature is fully supported and the Unicode specific characters, such as ✝☪✡☸☭, can also be used for the path name. It also affects data types and encoding of the string I/O functions. To define literal strings, <tt>_T(s)</tt> and <tt>_TEXT(s)</tt> macro are available to select either ANSI/OEM or Unicode automatically. The code shown below is an example to define the literal strings.</p>
+<pre>
+ f_open(fp, "filename.txt", FA_READ);      <span class="c">/* ANSI/OEM string */</span>
+ f_open(fp, L"filename.txt", FA_READ);     <span class="c">/* Unicode string */</span>
+ f_open(fp, _T("filename.txt"), FA_READ);  <span class="c">/* Changed by configuration */</span>
+</pre>
+</div>
+
+<p><br></p>
+<div class="para" id="vol">
+<h3>Volume Management</h3>
+<p>The FatFs module needs dynamic work area called <em>file system object</em> for each volume (logical drive). It is registered to the FatFs module by <tt>f_mount()</tt> function. By default, each logical drive is bound to the physical drive with the same drive number and an FAT volume on the drive is serched by auto detect feature. It loads boot sectors and checks it if it is an FAT boot sector in order of sector 0 as SFD format, 1st partition, 2nd partition, 3rd partition and 4th partition as FDISK format.</p>
+<p>When <tt>_MULTI_PARTITION == 1</tt> is specified by configuration option, each individual logical drive is bound to the partition on the physical drive specified by volume management table. The volume management table must be defined by user to resolve relationship between logical drives and partitions. Following code is an example of a volume management table.</p>
+<pre>
+Example: Logical drive 0-2 are tied to three pri-partitions on the physical drive 0 (fixed disk)
+         Logical drive 3 is tied to an FAT volume on the physical drive 1 (removable disk)
+
+PARTITION VolToPart[] = {
+    {0, 1},     <span class="c">/* Logical drive 0 ==> Physical drive 0, 1st partition */</span>
+    {0, 2},     <span class="c">/* Logical drive 1 ==> Physical drive 0, 2nd partition */</span>
+    {0, 3},     <span class="c">/* Logical drive 2 ==> Physical drive 0, 3rd partition */</span>
+    {1, 0}      <span class="c">/* Logical drive 3 ==> Physical drive 1 (auto detection) */</span>
+};
+
+<img src="../img/f7.png" width="828" height="288" alt="relationship between logical drive and physical drive">
+</pre>
+<p>There are some considerations on using <tt>_MULTI_PARTITION</tt> configuration.</p>
+<ul>
+<li>Only four primary partitions can be specified. Logical partition is not supported.</li>
+<li>The physical drive that has two or more mounted partitions must be non-removable. Media change while a system operation is prohibited.</li>

+<h4>Description</h4>
+<p>The <tt>f_lseek()</tt> function moves the file read/write pointer of an open file. The offset can be specified in only origin from top of the file. When an offset beyond the file size is specified at write mode, the file size is expanded to the specified offset. The file data in the expanded area is undefined because no data is written to the file. This is suitable to pre-allocate a cluster chain quickly, for fast write operation. After the <tt>f_lseek()</tt> function succeeded, the current read/write pointer should be checked in order to make sure the read/write pointer has been moved correctry. In case of the current read/write pointer is not the expected value, either of followings has been occured.</p>
+<ul>
+<li>End of file. The specified <tt class="arg">ofs</tt> was clipped at end of the file because the file has been opened in read-only mode.</li>
+<li>Disk full. There is insufficient free space on the volume to expand the file.</li>
+</ul>
+<p>Fast seek feature is enabled when <tt>_USE_FASTSEEK</tt> is set to 1 and the member <tt>cltbl</tt> in the file object is not NULL. This feature enables fast backward/long seek operations without FAT access by using CLMT (cluster link map table). The fast seek feature is also applied to <tt>f_read()/f_write()</tt> function, however, the file size cannot be expanded by <tt>f_write()/f_lseek()</tt> function.</p>
+<p>The CLMT must be created in the user defined <tt>DWORD</tt> array prior to use the fast seek feature. To create the CLMT, set address of the <tt>DWORD</tt> array to the member <tt>cltbl</tt> in the file object, set the array size in unit of items into the first item and call the <tt>f_lseek()</tt> function with <tt class="arg">ofs</tt><tt> = CREATE_LINKMAP</tt>. After the function succeeded and CLMT is created, no FAT access is occured at subsequent <tt>f_read()/f_write()/f_lseek()</tt> function to the file. If the function failed with <tt>FR_NOT_ENOUGH_CORE</tt>, the given array size is insufficient for the file and number of items required is returned into the first item of the array. The required array size is (number of fragments + 1) * 2 items. For example, when the file is fragmented in 5, 12 items will be required for the CLMT.</p>

When FDISK format is specified, a primary partition occupies the entire disk space is created and then an FAT volume is created on the partition. When SFD format is specified, the FAT volume starts from the first sector of the physical drive.</p>
+<p>If the logical drive has been bound to any partition (1-4) by multiple partition feature (<tt>_MULTI_PARTITION</tt>), the FAT volume is created into the specified partition. In this case, the second argument <tt class="arg">sfd</tt> is ignored. The physical drive must have been partitioned with <tt>f_fdisk()</tt> function or any other partitioning tool prior to use this function.</p>
+<p>Note that there are two partitioning rules, FDISK and SFD. The FDISK partitioning is usually used for harddisk, MMC, SDC, CFC and U Disk. It can divide a physical drive into one or more partitions with a partition table on the MBR. However Windows does not support multiple partition on the removable media. The SFD is non-partitioned method. The FAT volume starts from the first sector on the physical drive without partition table. It is usually used for floppy disk, Microdrive, optical disk and super-floppy media.</p>
+<p>The FAT sub-type, FAT12/FAT16/FAT32, is determined by number of clusters on the volume and nothing else, according to the FAT specification issued by Microsoft. Thus which FAT sub-type is selected, is depends on the volume size and the specified cluster size. The cluster size affects performance of the file system and large cluster increases the performance.</p>

+<h4>Description</h4>
+<p>The <tt>f_mount()</tt> function registers/unregisters a file system object used for the logical drive to the FatFs module as follows:</p>
+<ol>
+<li>Determines the logical drive which specified by <tt class="arg">path</tt>.</li>
+<li>Clears and unregisters the regsitered work area of the drive.</li>
+<li>Clears and registers the new work area to the drive if <tt class="arg">fs</tt> is not NULL.</li>
+<li>Performs volume mount process to the drive if forced mount is specified.</li>
+</ol>
+<p>The file system object is the work area needed for each logical drive. It must be given to the logical drive with this function prior to use any other file functions except for <tt>f_fdisk()</tt> function. To unregister a work area, specify a NULL to the <tt class="arg">fs</tt>, and then the work area can be discarded.</p>
+<p>If forced mount is not specified, this function always succeeds regardless of the physical drive status due to delayed mount feature. It only clears (de-initializes) the given work area and registers its address to the internal table. No activity of the physical drive in this function. It can also be used to force de-initialized the registered work area of a logical drive. The volume mount processes, initialize the corresponding physical drive, find the FAT volume in it and initialize the work area, is performed in the subsequent file access functions when either or both of following condition is true.</p>
+<ul>
+<li>File system object is not initialized. It is cleared by <tt>f_mount()</tt>.</li>
+<li>Physical drive is not initialized. It is de-initialized by system reset or media removal.</li>
+</ul>
+<p>If the function with forced mount failed, it means that the file system object is registered but the volume is currently not available. Mount process will also be attempted in subsequent file access functions.</p>
+<p>If implementation of the disk I/O layer lacks media change detection, application program needs to perform a <tt>f_mount()</tt> after each media change to force cleared the file system object.</p>

+<h4>Description</h4>
+<p>The <tt>f_sync()</tt> function performs the same process as <tt>f_close()</tt> function but the file is left opened and can continue read/write/seek operations to the file. This is suitable for the applications that open files for a long time in write mode, such as data logger. Performing <tt>f_sync()</tt> function of periodic or immediataly after <tt>f_write()</tt> function can minimize the risk of data loss due to a sudden blackout or an unintentional media removal. For more information, refer to <a href="appnote.html#critical">application note</a>.</p>
+<p>However there is no sense in <tt>f_sync()</tt> function immediataly before <tt>f_close()</tt> function because it performs <tt>f_sync()</tt> function in it. In other words, the differnce between those functions is that the file object is invalidated or not.</p>
