I got a Precision 380 with the latest BIOS (A09) and installed a WDC WD2500SB drive, which is 250GB in size. I hit the 137GB barrier, which is utterly annoying. OS is XPSP3, but the drive is showing already in BIOS as having only 137GB. This drive has no 137GB clip set or any other obvious limitation. It is connected via cable select, but as far as I know this doesn't make a difference.
Any advice on what to tweak to get access to the full drive space?
