5.6.5 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 Writ e 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 t o

format is taken from the Sec Cnt register (0=256). The use of this command is not recommended.
