￿Erase Sector(s) - C0h

This command is used to pre-erase and condition data sectors in advance of a Write without Erase or Write Multiple without Erase command. There is no data transfer associated with this command but a Write Fault error status can occur.

￿Flush Cache – E7h

This command causes the card to complete writing data from its cache. The card returns status with RDY=1 and DSC=1 after the data in the write cache buffer is written to the media. If the Compact Flash Storage Card does not support the Flush Cache command, the Compact Flash Storage Card shall return command aborted.

￿Format Track - 50h

This command writes the desired head and cylinder of the selected drive with a vendor unique data pattern (typically FFh or 00h). To remain host backward compatible, the CompactFlash Storage Card expects a sector buffer of data from the host to follow the command with the same protocol as the Write Sector(s) command although the information in the buffer is not used by the CompactFlash Storage Card. If LBA=1 then the number of sectors to format is taken from the Sec Cnt register (0=256). The use of this command is not recommended.
