aaaaaaggggggh, the disk now has only one RAW partition and I can't access it

Let's see what happens if I set all the partitions to primary, then restart

Same raw partition again, hmm...

What if I try the GPT write with sector size 512 again? and if the inaccessible E: and F: drives come up again I try intel on E: with the adjusted sector size?

augh, the E: drive is different this time it's 800MB, and there is no F: drive

I safely exited testdisk, let's see what I can do

I wonder what I should do about the bad GPT signature...

...another write error, and nothing's changed. I'm somehow in a worse situation than when I had the previous E: and F: drives...

One thing I noticed was that the analyse always paused a bit at cylinder 13 before give me the analyse messages.

Should I just give up and use PhotoRec?

I'm back, and I'm going to try advanced -> Boot -> List -> copy files

Don't forget to change sector size to 512...

Advanced: doesn't show boot option, but shows type option

Type: EFI and NTFS...

Boot: both sectors are bad, maybe I should do RebuildBS but I don't have any good drives to backup to...

Let's try list and copy first...

It seems to be working, but transferring my old accounts may be more complicated...
