How to fix and open recovered photos?
Unfortunately it is a common problem that you are unable to open recovered photos after using file recovery, undelete or photo recovery software on a SD card. In this post I will make some assumptions: Photos are on a memory card and therefor: File system is a variation of FAT (FAT32, exFAT) File type is… Read More »

The volume does not contain a recognized file system – RAW file system
The error ‘The volume does not contain a recognized file system’ CHKDSK error message, is what I’d call a ‘catch-all’ error message. It is very generic and it can have multiple causes, but in essence Windows and chkdsk have trouble determining the file system on a volume whether this is on a hard disk or… Read More »

Bottom half of JPEG is missing or grey or solid color
There’s basically three things that can be wrong if a JPEG opens but is partially grey:
1. File is too small. Let’s an average JPEG shot with same camera and settings is 4 MB and the ones that are damaged are like 1 MB or 2 MB. Then probably half the data is simply missing. These files can not be repaired.
2. Normal file size. Either part of the file does not contain image data or file does contain image data but is interrupted by some invalid data.
If part of the file does not contain image data then this is sometimes easy to spot using a hex editor. All of a sudden ‘random’ binary data stops and changes to FF FF FF or 00 00 00 etc.. Repair: Impossible.
In case the data is however is there but it is interrupted repair is often possible. JPG-Repair tries to detect and will try to get rid of the invalid data, however this does not always work. Current version detects invalid JPEG markers, common damage due to bad sectors and some type of corruption I observed a few times with images shot with certain Samsung phones.

Shoot video too? Then fragmentation is very likely to… Read More »

MP4 video recovery observations
I recently did a MP4 video recovery from a memory card (SD). It contained combined JPEG photo and MP4 video data, shot with a Canon EOS 600 D. Previous recovery attempts done by the customer resulted in the majority of the files being corrupt. All MP4 video was unplayable. Most recovered MP4 videos were tiny… Read More »
