Format Track

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 SecCnt register (0=256). The use of this command

is not recommended.
