I'm using a NCR 53c810 PCI card, it's been pretty good up to know.  I've
been considering swapping it for an adaptec 2940 though, see if that
changes anything.  I'm almost done installing 1.2.1, so I'll just see if
problems persist.  If they do, maybe I'll try the adaptec.

Thanks, I'm glad to here you agree that it doesn't sound like a failing
drive.  I don't want to have to buy another 4 Gig again <grin>.
