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.

Identify Drive
The Identify Drive command enables the host to receive parameter information from the
CompactFlash Storage Card. This command has the same protocol as the Read Sector(s)
command. The parameter words in the buffer have the arrangement and meanings defined in
Table . All reserved bits or words are zero. Table 40 is the definition for each field in the
Identify Drive Information.
