replace a 2-disk data (non-OS) RAID with a 3-disk RAID, so to
transition I actually had 7 (5 RAID + OS + a back-up IDE) drives
running, but ideally that would drop back to 4 or 5 when I'm done. The
largest supply I could get locally (Circuit City) is a 500W, so I'm
hoping that would be sufficient, and I could try to disable a few
components (the IDE, and possibly the optical) while building the
RAID.
the rest of the system is fairly standard by todays compents -- AMD
3800+, 3gb RAM, middle line video card, 1 optical drive, 2 case fans
could a low power state have caused the software issues (inability to
lauch several components), or likely I need to do a complete reinstall?
