I have used DBAN for a long time but on my new systems it does not work. No HDD is found. I also tried the Ultimate Boot CD and all the wipe utils can not find the drive. It is obviously there since I use the system daily. I ran scandisk to make sure there were no drive errors. I made sure none of the hdd security was enabled. I have a dell lattitude D830 with a 100gb 7200rpm drive. Any ideas what the deal is ?
