I'm rather dissappointed in the 3ware utility, it alternately claims both drives are ok(./tw_cli info c1 is different from ./tw_cli info c1 u0) I was relying on that too much, and ignored the possiblity of two drive failure. Looks like both drives would have failed at exactly the same time, which sounds like a power spike. I just got a report that another Windows98 workstation is randomly rebooting after an hour of uptime at the same facility, so I'm suspecting hardware failure like you did. I'll see what's up when I get there. Powermax will tell me what's up. Luckily the damage is contained to the data drive, I will be able to copy everything over to a new set of drives and not lose anything that's not trivially replaceable.
