I've got my new hard drive up and running, which is obvious, and used Symantec's Ghost 9 product as a backup, and was able to fully restore my drive in about an hour with 27 Gb's of information on it. A terrific product, never thought I'd need to use it for real, but glad I did.
With the old drive, after the DBAN ran, and said it was successful, I pulled the DBAN disk out of the CD drive, and tried to boot the hard drive, but, as I recall, got only a black screen, directing me to use F12, which of course took me to the blue screen with the BIOS, etc. I never tried to boot it with the hard drive completely out of the computer, so I didn't make that test, but I'm satisfied with what I saw, coupled with your expert advice, to feel confident that the drive is clean. I called, and emailed Dell, and they tell me that they clean all the return drives, and then physically destroy them. However, when it comes to private information, you can only trust yourself.
As an aside, I couldn't produce the DBAN disk from the Eraser product. I had to go to the DBAN site direct, where it was done with no problem. FYI, it took about 3 1/2 hours to clean a 160 Gb drive, using the default program, the suggested program.
Anyway, I really appreciate all your help. You provide a very important service, especially with these types of products, where they are a bit more technical than usual, and, done wrong, can not only leave a disk with private information still on it, but also destroy one in error.
Again, thanks for your help, Regards, Bill
