Fake memory cards

Not a week goes by where I am not confronted with loss of digital photos caused by fake memory cards. The sad news is that as these photos were never actually saved to the card they can’t be repaired nor recovered by tools like JPEG-Repair or JPEG Recovery LAB. A 32 GB card that you… 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.

Diagnostics of damaged and corrupt JPEGs

Not all corrupt JPEGs can be repaired. In fact, a large number of damaged JPEG files I receive on a daily basis can not. So I spend a fair amount of time on files that I nor anyone else can repair. About 90% of these non repairable files suffer from one of the following issues:… Read More »

Windows Photo Viewer: File appears to be damaged, corrupted or is too large The first thing you need to check is if other photo viewers can actually open the file.
