I had a problem where a fresh install of Windows 10 trashed the file system on my external hard drive (NTFS). I used Recuva, and TestDisk, and a couple other tools to recover the files. The problem I'm seeing is that when I recover a file, there is about a 20% chance that there will be a random corruption in it. For instance, a JPG file may turn purple half-way through the image (which seems to indicate to me that only one or a few bytes were corrupted). Videos have garbage show up every 10 seconds or so.
What is strange is that if I recover the file again, it may be fine. Or it may have an error in another part of the file. I had another hard drive in this same enclosure before and never had a problem, so I don't think it's a problem with the enclosure, although I wasn't using it on Win 10.
Any ideas on what could be causing this? I thought about trying another enclosure but Windows already corrupted the file system (see link above) so I'm afraid swapping enclosures may risk additional damage. Has anyone seen this before?
