Inplace recovery options? #46

Open DeveeiveD opened 1 year ago

DeveeiveD commented 1 year ago

This tool is exactly what I was looking for, however I'm curious why some in-place means of recovery are N/A. In my case I've got a drive which I used along with paragon apfs, obviously 3rd party apfs adapter blahh, blahhh..

Well so I have a peculiar situation, when I mount ext apfs drive with paragon apfs once on windows and plug it back into osx, drive works. As soon as I replug in osx, it fails with spaceman errors and zeroed-out block error. I'm like uber certain this issues could be fixed by simply resetting space manager or something or relinking blocks (I'm assuming failed writes at some point in the past), however I see that the only solution is decent knowledge of apfs and hex editor.... (esp funny when all validations in drat are OK)

Like I think it would be nice to be able to mod mappings, unless I'm crazy, but saving a snapshot (of few MBs) of block device should be enough for safety and that would be useful in the sense tht one wouldn't have to offload terrabytes of data Xd

Yeah, that's right, I want to implement this eventually, it's just quite the task to generalise. I'll leave this issue open to track progress on this feature, thanks for opening it!
