What about setting FUA on the next command after an error ?

Would this work or may the disk really keep stale data around ?

I don't have a recent SCSI spec at hand, but is there a command
we can send after an error to force a cache flush & invalidate
or will it only flush dirty datas to platter and not invalidate ?

Ben.
