CR2 File header problem

[RvG]

Hi,
I see some usefull tips here, but so far none of the ones I tried fixed the issue I have. I photographed a show yesturday and at the end my camera froze. After 10 minuted I had to restart is by removing the SD card. Now I find that quite some images (not all) are corrupted (I get a file format error with the exiftool). How can I figure out whether this can be repaired and if zo, how can it be done?
Kind regards and thanks in advance!

The best thing to do is to look at the file in hex.  If it is full of binary zeros, or random, then you are out of luck.  Most times the corrupted images can't be recovered, but sometimes there is an embedded preview that may be extracted.  Search for "extract_preview" in this forum for a script to do this.
