As I said earlier, I wanted to do a test run with the other laptop. I ran into a lot of problems trying to do that. I have a copy of DBan I used a long time ago on a CD. I've used it many times.
However, the other laptop won't boot from the CD/DVR drive. It doesn't show in the boot menu, with or without DBan in it.
So I tried to use a flash drive. None of the programs I tried to use recognized the USB when I tried to format it, GParted was one of them.
I went round and round trying to figure out why and what to do. Then my wireless stopped working. I had cords all over the place because I was going back forth between laptops. Every time I did, I had to stand up and sit back down several times.
I really want to wipe the drive. To do it, I'm going to have to do so on Last Option, but Last Option doesn't have a CD drive, at all. So I can't use my copy of DBAN on a CD.
On Last Option Gparted, Disk Utility and Disks all recognize the USB stick. I reformatted as Fat 32 so I could burn DBan to a the flash drive so I can wipe the disk. I'm not going to bother with a DOD wipe or moving the HDD. I can do it later if it comes to it.
While I'm at it, I'm also going to burn LM 21.3 to a flash drive.
