Okay, a simple "yes" would've worked... ;-)

Not surprised...

Hmmm, bummer...

        Alright, thanks for the info, Eric. Well, I do have a (so far)
winning bid of $6.00 on a BA-350. I wonder if that's what it really is...
I'll see what I can find for SBBs for it ( has only 2 power supplies). If I
can't use it, no big loss.
        Alternatively, I've been thinking about just converting a PC case to
a drive tower, and just have a pile o' disks. And if I want some RAID, use
software RAID. Yes, this is personal use. I'd never suggest software RAID in
a business...
        It'd be a shame to see 7 good 1GB HDDs go to waste...
