I had some hard drive troubles a few months ago after my power supply died and it turned out to be a pretty easy (yet time consuming) fix thanks to the help from people on these forums. So now that it's happened again I thought I'd come asking for help again. Here's the situation. I installed my new Radeon 9800 Pro today and as soon as I started up a game it killed my power supply. I went and bought a nice 500w power supply that ought to be able to handle everything. I have power and everything again, however the power supply took down all 4 of my hard drives on its way down. When I first started the computer after installing the new psu it didn't detect any hard drives. I managed to boot up to my windows xp installation disc and luckily it still detected the two partitions on my primary drive. I installed windows into a different directory on the primary partition. That has allowed me to at least get back into windows. Everything on my C: And D: partitions work fine once I'm in windows, however there are still problems during bootup. When booting up I have to go into my BIOS each time and auto detect the drive, it tries to auto detect during bootup on its own, but it is never successful. When I manually tell it to auto detect from within the BIOS it doens't detect it as a hard drive like it usually would. It detects its as "user" with the values entered in for me. Other hard drives do the same thing with the "user" values, but once I'm in windows there is no sign of those drives. Not even using the drive restorer program I used to recover all of my files last time something like this happened. A friend suggested flashing the most recent BIOS, which I did. It didn't really do much help though. ANY other suggestions would be greatly appreciated, thanks.
