5.1.4

Format Track–50H

This command writes the desired head and cylinder of the selected drive with

an FFh pattern. To remain host backward compatible, the 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 card does not use the

information in the buffer. If LBA=1 then the number of sectors to format is

taken from the Sec Cnt register (0=256).

Note: The Format Track command in Table 41 is no longer recommended. The

command is supported to guarantee backward compatibility.

5.1.5

Identify Device–ECH

The Identify Drive command enables the host to receive parameter

information from a 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 “0”.
