Sorry, it's not a 650W, it's a 600W PSU, my mistake. No matter, that's just Zalman's conservative rating, another manufacturer, OCZ, repackages the same PSU and rates it at 700W. I did have a problem with low-quality PSU's in the past, I used to go for cheap 400W units based on price mostly, until I started noticing that certain instabilities were being caused. So I decided to properly invest in this one, this time. However, even still, a single 12V rail can only supply upto 18.5A, which is 222W. I think two of those rails are dedicated to the motherboard, and one for a high-end video card (don't have one of those), and the rest for anything else, which probably means the hard drives. Is 222W enough? I would've thought so. > So, you said that only one drive were disappearing or it's something random > and every drive disappears from time to time? It just happened once, it isn't a recurring thing (yet). But once is enough in this case. It's not supposed to do that at all, not unless the drive itself dies which didn't happen. Yousuf Khan

Thats also a classic with memory leak problems, they dont happen that often, only after quite a while after the reboot.

I have noted drives disappearing when there is a conflict with a network mapped drive, or a drive SUBST command. I am not sure if this will happen with an internal drive. Michael

Yes it can.

I'd have had to have actually tried to map a network drive at the time this internal drive disappeared. The internal drive just disappeared by itself, and as I said before there are entries in the Windows System log showing when it happened. It showed controller problems at the time, with no other details beyond that. Yousuf Khan |
