It might also help to switch to the debugging output console window (it's been years since I've run through the install process, so I don't know whether it's alt-f2 or f3 or what). You might see some diagnostics that'll help. > If it helps, I'm running an Asus P2B-DS motherboard, BIOS 1009 (latest) which > incorporates the adaptec SCSI bios v2.11 for the onboard 7890 chipset. Maybe > there's a wierdity with this setup and those drives? Nah, shouldn't be. The 7890 trouble was fixed before 3.2.

Yeah, it would be nice to figure out what's going on. My theory probably isn't it. > Thanks for the reply--I'll try doing the above tonight when I get home and > will report back. Cool, thanks.
