After swapping the "suspect" drive around in an attempt to get the failure to move to the other disk in the pair I actually got a failure on the OTHER channel (in other words, the problem followed the DISK) That got followed up with a soak test with DOS-based diags, which eventually spat out a hard failure code. It took some effort, since the problem doesn't appear on a quick test nor does it show up at the same block all the time - indeed, the block where it finally pukes is all over the place. Back to Maxtor it goes - it appears that FreeBSD's driver (and the bios, etc) is not at fault here, and was indeed reporting a "real" failure. I guess the mirroring code in 5.3-STABLE actually works :-> -- Karl Denninger (karl@denninger.net) Internet Consultant & Kids Rights Activist http://www.denninger.net My home on the net - links to everything I do! http://scubaforum.org Your UNCENSORED place to talk about DIVING! http://www.spamcuda.net SPAM FREE mailboxes - FREE FOR A LIMITED TIME! http://genesis3.blogspot.com Musings Of A Sentient Mind
