Byte 1 If the disable page out (DPO) bit is 1, the cached data that
the drive receives during this command has the lowest
priority for being retained in the cache. If the DPO is 0, the
cached data has the highest priority for being retained in
the cache.
If the forced unit access (FUA) bit is 1, the drive must access
the disc to write the data sent by the initiator, even if the
data can be stored in the cache. If the FUA bit is 0, the drive
can write the data to the cache or the disc.
Bytes 2–5 The
logical block address specifies the logical block where
the write operation begins.
Bytes 7–8 The transfer length specifies the number of contiguous
logical blocks of data to be transferred. A transfer length of
0 means that no logical blocks are to be transferred; this is
not an error.
3.6.4 Seek (10) command (2B
H
)
The Seek (10) command requests that the drive seek to the specified
logical block address. This command is the same as the Seek (6)
command, except that the CDB includes a 4-byte logical block address.
The Seek (6) command is described in Section 3.4.8. on page 47.
