[VU+ Duo4K] Lost all recordings

[BrianTheTechieSnail]

I don't think Vix can do a low-level format, it only seems to do an initialize which clears the FATs or whatever the equivalent is in the linux file system. Personally I would not trust the disk, I would install a replacement disk and format the replaced disk appropriately.

What convinces you that the disk failed rather than the box crashing and writing garbage over some important data structures?

Update from me, I did a full scan with testdisk and it took about 8 days on my 2tb disk. It recovered a list of filesystems but each one was corrupt and so it could not be loaded. The disk itself seems ok and passes diskcheck without errors. So I ahve lost my data. It sounds like Vix cannot programtically do this so I can only presume the disk itself has an issue. I'm still going to use the disk but backup anything I want to keep and see how it goes.

Is this testdisk from CGSecurity? Did is say anything about the drives health or about SMART information?
