I tried turning off the PC and restating - same situation. However, once it is frozen, it remains locked until a power cycle or hardware reset.' I read this article and specifically this line: 'The drive can be frozen by the BIOS, the OS, or possibly a software application. Running all these tools from the UBCD 5.1.1 SEATools tells me that the drive is Security Freeze Locked.

Boot & Nuke kept erroring out when I tried to wipe the drive. I put it into my utility computer (HP a1310n) on which I do this kind of thing. I really don't know why that would be since I don't think they are stored on the same sectors internally, it could be a coincidence.So, all I wanted to do was take this drive out of an old computer and wipe it using Darik's Boot & Nuke. I should add that a majority of the files that went bad were at the bottom of my folder list, which is listed alphabetically. What would be the best way to test this drive because clearly the s.m.a.r.t status shows no issues. I have backed up what I could onto a new drive, but am wondering if this drive is shot or not? I would never use it for important data again, but maybe for some type of redundant drive. The 4tb drive shows a completely healthy s.m.a.r.t status via crystal disk check. They worked fine again for a year but now cannot be salvaged, even after using iso buster. Many of these files were salvaged from another hard drive that became raw and had to be reformatted and recovered via easeus recovery software. They show in the folder and mount via virtual clone drive, but none of the software programs (vlc, powerdvd, make mkv) recognizes them.

I have a 4tb Seagate drive that suddenly has about 50 bd iso files not playing.
