ATA Command Description
5.1.4. Format Track—50H
NOTE: The Format Track command in Table 5-6 is no longer recommended. The command is supported to
This command writes the desired head and cylinder of the selected drive with an FFh pattern. To remain host
backward compatible, the CompactFlash Memory 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 Card. If LBA=1 then the number of sectors to format is taken from the Sec Cnt register
(0=256).
5.1.5. Identify Drive—ECH
The Identify Drive command enables the host to receive parameter information from the CompactFlash Memory
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 5-8. All reserved bits or words are zero. Table 5-8 is the definition
for each field in the Identify Drive Information.
