I am looking for options regarding recovering deleted files (don't recall if corrupted applied).
Filesystem for the corrupted files are VFAT-formatted on a USB, though I run a Linux system (but can use Windows if necessary). The original files were created using Windows.
The corrupted files I have found (so far) are images from a scanner using "pictures" setting on the scanner to scan the images. Many images are not corrupted, but some are. Part of the image is present, but most of it is covered in a 'grey' color which looks like a piece of dark grey paper, but it is definitely not.
