I built an Intel-based system that’s running on a Gigabyte 945P-S3 motherboard. I’m chugging on three SATA hard drives—a 120GB, 250GB, and 500GB. The processor is a Core 2 Duo E6300 running at 1.86GHz, along with 4GB of 667MHz memory and a GeForce 5800 Ultra Extreme 512MB graphics card.

So what’s my problem? The system runs OK with 64-bit Vista Ultimate SP1, but I have a problem with the 500GB drive disappearing. It doesn’t show up in any of the installed diagnostic programs, Windows disk management, or anywhere else. If I swap the power supply connector around, the drive will show up for a while, but then it disappears again. (The power supply is a Thermaltake 800W unit that’s about a year old, and it has swappable plug connectors.)

 Most times a reboot shows the disk in the BIOS as “BzBzBzBz...” What’s going on?
