 <tr><td>CTRL_SYNC</td><td>Makes sure that the device has finished pending write process. If the disk I/O layer or storage device has a write-back cache, the dirty cache data must be committed to media immediately. Nothing to do for this command if each write operation to the media is completed within the <tt>disk_write</tt> function.</td></tr>
 <tr><td>GET_SECTOR_COUNT</td><td>Retrieves number of available sectors, the largest allowable LBA + 1, on the drive into the <tt>LBA_t</tt> variable pointed by <tt class="arg">buff</tt>. This command is used by <tt>f_mkfs</tt> and <tt>f_fdisk</tt> function to determine the size of volume/partition to be created. It is required when <tt>FF_USE_MKFS == 1</tt>.</td></tr>
-<tr><td>GET_SECTOR_SIZE</td><td>Retrieves sector size used for read/write function into the <tt>WORD</tt> variable pointed by <tt class="arg">buff</tt>. Valid sector sizes are 512, 1024, 2048 and 4096. This command is required only if <tt>FF_MAX_SS &gt; FF_MIN_SS</tt>. When <tt>FF_MAX_SS == FF_MIN_SS</tt>, this command will be never used and the read/write function must work in <tt>FF_MAX_SS</tt> bytes/sector only.</td></tr>
+<tr><td>GET_SECTOR_SIZE</td><td>Retrieves sector size, minimum data unit for generic read/write, into the <tt>WORD</tt> variable pointed by <tt class="arg">buff</tt>. Valid sector sizes are 512, 1024, 2048 and 4096. This command is required only if <tt>FF_MAX_SS &gt; FF_MIN_SS</tt>. When <tt>FF_MAX_SS == FF_MIN_SS</tt>, this command will be never used and the read/write function must work in <tt>FF_MAX_SS</tt> bytes/sector.</td></tr>
 <tr><td>GET_BLOCK_SIZE</td><td>Retrieves erase block size of the flash memory media in unit of sector into the <tt>DWORD</tt> variable pointed by <tt class="arg">buff</tt>. The allowable value is 1 to 32768 in power of 2. Return 1 if the erase block size is unknown or non flash memory media. This command is used by only <tt>f_mkfs</tt> function and it attempts to align data area on the erase block boundary. It is required when <tt>FF_USE_MKFS == 1</tt>.</td></tr>
 <tr><td>CTRL_TRIM</td><td>Informs the device the data on the block of sectors is no longer needed and it can be erased. The sector block is specified in an <tt>LBA_t</tt> array {&lt;Start LBA&gt;, &lt;End LBA&gt;} pointed by <tt class="arg">buff</tt>. This is an identical command to Trim of ATA device. Nothing to do for this command if this funcion is not supported or not a flash memory device. FatFs does not check the result code and the file function is not affected even if the sector block was not erased well. This command is called on remove a cluster chain and in the <tt>f_mkfs</tt> function. It is required when <tt>FF_USE_TRIM == 1</tt>.</td></tr>
