i had the exact same thing happen to my asus netbook at the beginning of may - and I thought it was weird that it happened right after a windows update. called up my geek squad friend, and he said some stuff about a certain windows update causing issues, but I didnt really get what he said. but to fix my drive, he unplugged it from my netbook and hooked it up into his own desktop tower and got it running (though I dont know if it took any special work), copied all my files out for me onto one of my externals, and then formatted the drive and reinstalled windows for me. it was TOTALLY fine after that. (well, except for having to re-do all my passwords for email accounts, shopping sites and such cause I had everything set to "remember my password for this site" hehe. THAT was a pain). so if youve got a friend with a little savvy and a copy of windows, have him do that.
