Thanks. Actually the system is on UPS. It's in a server room with a huge UPS, and got hit with the rolling brown-out on Saturday. The UPS, however, only ran 12 minutes!

I'll give SpinRite a try. The drives seem fine, I just don't see why the partition map disappears even after I install new ones. Unfortunately, I'm not in the same locality as the 4500. Do you know if SpinRite can be booted from grub, or even a USB key? (I know, look in the docs...).

Also, Adaptec used to have the latest O/S for these for free with registration.
Now that Overland Storage has taken over -- and dropped the products -- I can't seem to find any upgades. Any ideas? I'm more interested in getting the drives working again at this point, though, so just an aside.

Thanks again.
