Datasheet

 Security Freeze Lock – F5h
 Security Freeze Lock – F6h
 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.
