How to repair damaged jpg?

[mlv]

Hi

While batchconverting in xnview (1.70.2) I accidententally deleted my original jpg's.
I recovered them with an undeleting program, but they are now inaccessible by xnview or several other viewers.
They still have a jpg extension but according to the program EXIF the files start with (by example) 0x85 0xa0 and so is not a jpg.

Anybody a brilliant idea how to repair this.

Can you hex edit the file and just change the first 2 values? Not sure if that would work or not...

unfortunately it changes nothing

When searching the internet for keywords "JPG repair damaged file header" you will get good hits with valuable hints.

I've only read a very small bit of the info found. One of the hits which I find good is in Google answers. In the discussion also a software named "Pixrecovery" is mentioned which is intended for repairing JPG files. The link is http://www.officerecovery.com/pixrecovery/, there's a demo version, the software is not free.

Let us know how you go...
