Alright, hopefully some answers can be found here. I've posted questions here before and everyone here has always helped. My wife has a HP DV2125nr. She bought it prior to Vista being released, but was able to get an upgrade disk for free from HP due to the purchase date. So, it's originally an XP install with a Vista upgrade. For the past couple of months (at least) we've been attempting to run a defrag and it states that we need to run a test on the disk first, so we set it to test at the next reboot. When CHKDSK comes up it gets to 3% and stops....no just slows down, but stops. I'm a techie myself, having built systems from scratch and beta tested Vista (and the upcoming SP1), and this one just has me stumped. I've run other diag programs within Windows on the drive and it tests fine, but CHKDSK failing is usually a sign of an issue. Geek Squad had it for a week and found nothing (no surprise), and HP states it out of warranty and won't do a thing. Any ideas?
