If these are corrupt then individual files are corrupt. With the image you can then see if you can carve files like I do in the video. The more often a specific area of NAND was programmed/erased the more fragile and susceptible to data bleeding it is.Īnyway, wise is to image the drive, again as u/DR-Throwaway2021 already suggested. Although individual files look corrupt, this is a result of the file allocation tables being corrupt, data bleeding happened in those areas possibly as a result of these being often updated in combination with poor wear-leveling. This video was about a USB flash drive that had been kept in a drawer for several years, it was okay when it was put there. Since file system meta structures can fall victim to this 'data bleeding' too I occasionally see the photos themselves being okay but appearing to be corrupt due to file system errors. So this can cause individual photos to 'corrupt'. One flipped bit is all that's needed to corrupt a JPEG file and CR2 RAW data is in effect stored as (lossless) JPEG too. Not accusing you slacking but these things may be hard to diagnose.Īs u/DR-Throwaway2021 these drives (assuming USB flash drive) 'bleed data' eventually leading to bit-flips.
