Transfer Length
The Transfer Length field specifies the number of contiguous logical blocks of data that shall be transferred to the drive's
cache memory.
0
The contiguous logical blocks up to and including the last logical block of the logical unit shall be transferred to the
drive's cache memory.
Any value other than 0 indicates the number of logical blocks that shall be transferred. The drive may elect to not transfer
logical blocks that already are contained in the cache memory.
If the Immed bit is zero and the specified logical blocks were successfully transferred to the cache memory, the drive shall
return Condition Met status. If the Link bit (see Control Bytes in Section 11.2.1.6) is one, the drive shall return Intermediate–
Condition Met status.
If Immed is one and the unlocked cache memory has sufficient capacity to accept all of the specified logical blocks, the
drive shall return Condition Met status. If the Link bit is one, the drive shall return Intermediate–Condition Met status.
If Immed is one, and the unlocked cache memory does not have sufficient capacity to accept all of the specified logical
blocks, the drive shall return Good status. The drive shall transfer to cache memory as many logical blocks as will fit. If the
Link bit is one, the drive shall return Intermediate status.
