Recover Canon CR2 RAW photos

Recover Canon CR2 RAW photos. Canon CR2 raw files contain unprocessed raw sensor data. Depending on the camera’s resolution they tend to be quite large and due to typical usage patterns (preview photo > dismiss/delete file > shoot new file etc.) the files become easily fragmented. Shoot video too? Then fragmentation is very likely to… Read More »

MP4 video recovery observations

MP4 Video recovery and corrupt video 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.… Read More »

Photo recovery: Easeus Data Recovery vs JPEG Recovery LAB

The corrupt JPEGs that weren’t corrupt

Often I am asked to repair JPEGs that can be opened but don’t display correctly. Many of those look okay for some part, but turn into a grey area at some point. Repairing these files (or recovering them as we’ll see) isn’t always straight forward and sometimes requires some detective work. Half grey photos In… Read More »

Corrupt CR2 and NEF files due to file fragmentation

As a result fragmented files recovered by such tools will be corrupt. In such cases JPEG Recovery LAB can help you recover fragmented files. However, recovered files may… Read More »

Corruption can be caused by a few different things, IF we assume the software didn’t make errors like guessing the wrong file system. Parts of the file were overwritten after deletion. Overwritten data can not be recovered. File occupied… Read More »

Chkdsk turned all JPEGs into .CHK files

The other week I received a SD memory card on which chkdsk was automatically run. Chkdsk turned all JPEGs into .CHK files. When Chkdsk removes certain files from the file system, it saves the content of the clusters that belong to the file in .CHK files. They are typically written to a folder called ‘FOUND.000’. As… Read More »

Why photo recovery and undelete software recover corrupt jpeg files.

In this post I will try to explain why most tools fail recovering fragmented digital photos and instead recover corrupt JPEG files. If half the data is missing due to file fragmentation I can not repair the JPEG (see: JPEG Repair Service). It is better to have a tool that can recover fragmented files directly. Why… Read More »

For my JPEG Repair Service I am often asked to repair JPEGs that only partially display. The bottom half of JPEG is missing or greyed out, solid grey. I some times can repair this and I some times can not. It all depends on if there is data present I can work with. Fact is  that the image… Read More »
