jpg Header Corruption

Recommended Posts

:hello: all

I've just recently screwed a hard drive up, accidentally deleted a partition and tried to fix it with partition magic in a moment of panic :blushing: this only made matters worse as it then started to format :o not good! So i then decieded to actually look into what i'd done and see if there was a cure (should have done this in the first place) i managed to recover most of the stuff i needed using a proggy called getdataback

only thing is every last jpg and illustrator file (.ai) is corrupt, i think it may be the headers in the jpg's as for the .ai's have no idea, guessing it could be a similiar problem. But i'm pretty sure i can get these images (mostly iriplaceable photos) back as binarybiz's viryuallab offers an image preview tool, this shows the pictures! and their ok :thumbup

But if any one could shed any light on the situation before i go and blow yet more £££££'s on file recovery, would be very gratefully, especially relating to the illustrator files as these are pretty important projects i'm working on at th mo

Cheers in advance to anyone that's willing to help

If you want to figure out whether or not the file headers are intact, get a JPG file format specification and a hex editor. All JPG files begin with the bytes 255, 216, 255, 224, 0, 16, and then "JFIF".

.AI files are actually a text format, so corruption should be quite easy to spot. (At least for version 8.0 which I have...)

I accidentally came accross some softeare that seems to be doing the trick! whilst browsing the msfn forum's i spotted a post on defragmentation, and that O&O have a very good, tool, turns out they also have good hd recovery software too, i've got nearly all my jpg's back using this, and am now trying to get the .ai's back! :thumbup

I personally use FinalData Enterprise v2.0 to recover files. I even recovered images off my USB stick last night. Also, PerfectDisk is the best defragmenter. You can't really get better than that.
