The SYNCHRONIZE CACHE command ensures that logical blocks in the cache have their most recent data value
recorded on the media.
- Logical Block Address is to specify where the operation is to begin.
- Immed (immediate) must be zero. An immediate bit of zero indicates that the status shall not be returned until
the operation has completed. If the Immed bit is set to one, the drive returns a Check Condition status. The
sense key shall be set to Illegal Request and the additional sense code shall be set to Invalid Field in CDB.
- Number of Blocks specifies the total number of contiguous logical blocks within the range. Number of Blocks
of zero indicates that all remaining logical blocks on the logical unit shall be within the range.
