I've been asked to repurpose 2 Seagate drives that came out of HP printers. When mounted to PCs they are IDed as "HP Secure Hard Disk". They cannot be accessed in Windows Explorer for the typical format. I tried DBAN and it reported error "Could not access sector ####" (starting from 0 and ran though all sectors). I then tried ActiveKillDisk and while it progressed 0-100% it returned the same error.
I'm going to try SDelete next, but not feeling confident it will work.
Is there any software that will allow you to wipe these drives?
Would HP Disk Sanitizer work? I've never used it.
