Move Medium Command (A7H) - Seagate Ultra160 Product Manual

SCSI Interface Product Manual, Rev. B
block descriptor. A NUMBER OF BLOCKS field value of zero indicates that all of the remaining logical
blocks of the logical unit have the medium characteristics specified by the block descriptor.
b. For drives that have capacity programming capability, these bytes do not report back the drive capacity
on some models. These bytes are always zero on those models. Some models do report drive capac-
ity in bytes 0, 1, 2, and 3, so those bytes will be nonzero. See individual drive's Product Manual, Vol-
ume 1, for the drive of interest.
[7] The BLOCK LENGTH, as defined after a format function, specifies the length in bytes of each logical
block described by the block descriptor. Default is 512 if no MODE SELECT command is received before
the format command. The usual valid values are 256 through 4096. Some drive products can format down
to 180 bytes per sector. Some products can only format an even numbered value of bytes per sector (180
- 4096).
[8] When used with the MODE SENSE command, a DPO-FUA bit of zero indicates that the target does not
contain a cache memory or does not support the DPO and FUA bits. A DPO-FUA bit of one indicates that
the target supports the DPO and FUA bits.
