What happens after a power failure or SCSI Device Reset during a write?
On a SCSI Device Reset command, all data in the drive s cache is written to the media. This may result in a partial block on media, especially with very large blocks (e.g., 10 MB). A power failure will clear the drive and cache without completing the write, since there is no battery back-up within the DLT drive. A Write Filemarks, Count=0 synchronizes the media with the cache. The data in cache is written to media along with any filemarks. A bus Reset before the Write Filemarks command completes will not interrupt the synchronization. A power failure will.
