There’s always a first time…
During my holiday trip I realized, something was wrong with my compact camera. Not that it showed any signs of a problem when taking shots. No, that would have been too profane. But when I tried to mount the SD card in my Linux laptop to send some of the pictures by mail, it showed this:
There was clearly something wrong and I immediately fired up
dd to make a backup of the card. That went fine, so the camera must have had a memory corruption when writing the FAT. Sadly, this happend when the holiday was almost over and the camera had taken some memorable shots by then.
fatcat: If both copies of the FAT are broken in exactly the same way they can’t perform their magic. But there is one tool which won’t let you down: PhotoRec.
photorec was able to recover every JPG, MOV and RAF on the card. The file dates (which I use for renaming my files for the archive) could subsequently be restored with
exiftool -r -overwrite_original '-FileModifyDate<DateTimeOriginal' recovered_dir.
All fine? Well, almost.
The compact camera is a Fuji F600EXR, so I almost always shoot in DR EXR mode (outside). The RAFs then contain two frames – the standard and the underexposed shot. But the recovered raw files were missing the latter one.
So I described my problem on the cgsecurity forum and Christophe Grenier was quick to ask for a sample. Within a few days he came up with a new version. The current
7.2-WIP is now able to recover multi-frame RAF raws.
Here’s a screenshot of a recovered raw in HDRMerge for you to enjoy:
It does not only prove the recovery of both frames but also that my fellow @heckflosse runs his own petrol station network in Sweden.
