Yes, everything is up to date, BIOS, Drivers, and WinXP SP2 (Home and
Professional). I'm a stickler that way.

As I also noted before, my 200Gb and 240Gb work, but not the 400+
Gigabyte drives. Oddly, a hard drive information program I used
reported that the 200Gb and 240Gb drives didn't support 48bit data
transfer. I thought all hard drives over 137Gb required 48bit support?
