ATA Command Description
This command is effectively a NOP command and only implemented for backward compatibility with earlier
SanDisk SDP series products. The Sector Count Register will always be returned with an 00H indicating Wear
Level is not needed.
5.1.24. Write Buffer—E8H
The Write Buffer command enables the host to overwrite contents of the CompactFlash Memory Card’s sector
buffer with any data pattern desired. This command has the same protocol as the Write Sector(s) command and
transfers 512 bytes.
5.1.25. Write Long Sector—32H, 33H
This command is provided for compatibility purposes and is similar to the Write Sector(s) command except that it
writes 516 bytes instead of 512 bytes. Only single sector Write Long operations are supported. The transfer consists
of 512 bytes of data transferred in word mode followed by 4 bytes of ECC transferred in byte mode. Because of the
unique nature of the solid-state CompactFlash Memory Card, the four bytes of ECC transferred by the host cannot
be used by the CompactFlash Card. The CompactFlash Card discards these four bytes and writes the sector with
valid ECC fields. This command has the same protocol as the Write Sector(s) command.
