Thanks. I've been having problems with the drives in my G5, and
wondered if the power supply might be a cause of the problem. It kinda
feels like a heat problem, in that after a while one or more drives
conks out (they're RAID Mirrored together in 2 pairs of 2). Right now I
have one RAID set with its primary drive up and its secondary drive
down, and the other RAID set appears to be in the opposite state, with
its primary drive down and its secondary drive up. Unfortunately, that
2nd RAID set is not showing up on the desktop or in "/volumes." I find
it strange that "RaidEye" tells me it can see that 2nd RAID partition
when Disk Utility can't see it.
I'll be playing with rotating drives once I get backup drives big enough
to hold everything. The new drives arrive tomorrow (and will go into my
external FW800 RAID Mirrored box.)
My G4 also has 4 drives in it with one drive not showing up, but I think
the problem there is a cable problem (data or power, maybe both.) It's
not a drive problem, since I swapped in a new working drive where the
problem was and I still get the same "I/O error" when I try to format it.

Yes. I have a 2GHz G5 with 4 internal drives and it works fine. Mine
was a home-made job. I looked into that bracket that you can buy, but
it was too expensive.
I bought a two port SATA card from OWC, then bought a molex to dual SATA
power plug and a dual molex plug off ebay for about $10 total . I use
the power going to the optical drive. I put the dual molex plug there
to split power between the optical drive and my two extra internals.
Then the dual SATA power plug obviously goes on the other molex plug.
The two drives are sitting vertically under the optical drive, right up
against the front grille of the machine. The "sides" of the drives are
right up against the grille, and I use screws to secure them to the
front. It actually doesn't look too bad. Then I put little rubber feet
on the "bottom" of the drives (almost on the floor of the inside of the
machine) to keep them from vibrating. I've used this setup for over a
year with no issues. The internal temperature of my machine is usually
right around 150F, which is within normal operating temperatures.

Does anyone know how to evaluate whether a power supply in a G5/2ghz DP
has enough "oomph" to handle 4 internal disk drives?
