This is an odd one. I partially formated a SATA WD 160GB drive, ran out of time and had to shut it down. Took it home, and now XP install gives me the "Setup cannot access this disk" when you go to select your partition/create/delete etc (after the F8 screen). I can put the drive in my home system, partion and format it just fine, but as soon as I put it back in the tower it wont detect. I used the same SATA and power cables in both systems so i know the cabling is good and ive tried using different sata ports (there are 4) and the same thing happens. I tried to repair the MBR and that did nothing. Not sure what happened, but I dont want to assume the drive is dead as its brand new, and im thinking there is something ive missed.
