+<dl class="ret">\r
+<dt>STA_NOINIT</dt>\r
+<dd>Indicates that the device is not initialized. This flag is set on system reset, media removal or failure of <tt>disk_initialize()</tt> function. It is cleared on <tt>disk_initialize()</tt> function succeeded. Media change that occurs asynchronously must be captured and reflect it to the status flags, or auto-mount feature will not work correctly. When media change detection feature is not supported, application program needs to de-initialize the file system object with <tt>f_mount()</tt> function after the media change.</dd>\r
+<dt>STA_NODISK</dt>\r
+<dd>Indicates that no medium in the drive. This is always cleared on fixed disk drive. Note that FatFs does not refer this flag.</dd>\r
+<dt>STA_PROTECT</dt>\r
+<dd>Indicates that the medium is write protected. This is always cleared on the drives without write protect feature. Not valid while no medium in the drive.</dd>\r
