It does seem there's lots of cheap implementations, probably based on a few poor controller chips, that work fine for 99·99…% of transactions and that's probably okay if just accessing a few files but the number of sectors on a drive makes that 0·00…1% bite. What I've done in the past is take a digest of source with it not in the caddy, move it to the caddy, copy source to destination, flush any caches, compare the earlier digest to one of the destination. It needs careful tracking of what's being digested though to ensure it's the same both times, e.g. the destination drive might be bigger. -- Cheers, Ralph. -- Next meeting: BEC, Bournemouth, Tuesday, 2019-12-03 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk/ New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
