You'd be surprised.
I've encountered two different systems in the past 4 months using hardware
RAID where the controller/firmware/driver apparently dropped the ball during
a drive failure/replacement. These were new systems from big name vendors
and had the latest drivers and firmware applied. These days, the only array
controllers I trust are made by Compaq (and I've done some pretty abusive
things to them without any corruption of data at all).

Hmmmmmm.... that is a good point. The assumption was that any failure
that required restoring from tape would have destroyed the logs as well --
i.e., something like a complete disk failure. A failure such as you
describe is perhaps not very likely, but certainly possible.
I will move to have circular logging disabled on any Exchange system we
maintain.
Thanks for the advice!
