Comment 140 for bug 84603

So it would appear that this is, in fact a hardware issue (at least in my case). Like I said, my mem, mobo, proc, and HDD's all were good. The one thing I never considered: power supply.

It would appear that one of my drives was consistently receiving too little power. It just occured to me out of the blue when I was sitting there dealing with this problem and heard what I thought were my fans spinning down, then back up again, within 2 seconds.

I had been using a splitter that splits one Molex 4-pin adapter into 2 SATA power adapter. I changed the wire configurations around so that each 4-pin Molex was only allocated one HDD per. Since then I show 2 days of system uptime with no recurrence of this problem.

I've since ordered a new power supply, as this one is most certainly about to die.

Thanks for the responses, everyone. Sorry to waste time and effort!
