I had Windows running on the hard drive before, but I tried switching motherboards and processors and that resulted in a huge mess, so I ended up just erasing the hard drive, which took quite a bit of effort. Now when I try to get Windows Set-up to recognize it so that I can format and install Windows on it, it says it can't find any hard drives. I've only had the hard drive for about 3 or 3 and a half monthes. Another thing to note is that my motherboard doesn't have SATA ports integrated, so I have a PCI card that has 1 internal and 1 external SATA ports. I did have Windows load the drivers for them at the beginning of setup. I have a K7VME motherboard with a AMD Athalon XP 2600 + processor, ATI Radeon 9500 Pro video card, Sound Blaster 5.1 Live sound card, the SATA PCI card, CD-ROM drive, Floppy Drive, 80 GB SATA hard drive. This has been stressing me out for a few days and I can't figure it out. If any of you can help me, it would be greatly appriciated. I'll try to help other people out aswell.
