recover corrupt files...

| tim harrison 2006-01-10, 8:04 pm |
| ....not sure where to go to ask this question, but my old friends at psp may
be able to help. i have about a hundred or so jpg's burned to cd at a photo
express-type place from an sd card used in a digital camera whilst on
holidays many moons ago. i have been unable to view ANY of the photos (there
were also some mp4's taken form the card...sigh...) using any of the
software i currently own. psp tells me "the specified file cannot be
identified as a supported type". macromedia fireworks tells me "could not
open the file. unknown file type." windows picture and fax viewer just
refuses to do anything at all. i've also used photorescue pro to no avail.
has anyone got any clue what my next step should/could/would be to recover
these files. puh-lease!!!
cheers for now

You might want to try IrfanView. It is an excellent free viewer that opens
roughly about a gazillion different file types. www.irfanview.com

Just a thought: you KNOW the files are JPG but some photo services burn
your photos to CD and also change their extension to some special
proprietary extension recognized only by the freebie viewer program they
include on the CD.
I once ran into such a case, and merely copied the files to my HD, then
renamed them all with the .JPG extension... they worked perfectly after
that simple step. Another idea would be to examine one photo file in a hex
editor and verify that you can see the letters JFIF near the top... that
would mean the file was indeed in proper JPG format. I think your photo
service would NOT have messed with the file format, only the extension.
Suggest you take a very close look at your CD :^)

Sometimes JPGs are written with a lot of junk in the file header that
can stop other programs from opening them correctly. The extra stuff can
be cleaned out using the freeware JPEG Cleaner from
http://www.rainbow-software.org/pro...#JPG%20Cleaner. This is a
lossless process that doesn't recompress the file, just re-writes a copy
with a standard JPG header. Probably a good idea to copy the JPG to your
hard drive, and make sure they're not set to read only, before running
JPEG Cleaner.

| hmmm - i just downloaded a freeware hex editor, and opened one of the jpg's
(all the files already have the jpg extension). every entry is "00". i have
no idea what that means, but i'm guessing it's not good. there's no writing
anywhere. i should say all the programs i've tried to open any of these
files in all "see" the .jpg (windows explorer lists file sizes for each
which would be about right) in the directory, but fail each and every time
to open them..grrrrr.....
cheers for now

If each .jpg file contains nothing but 00 entries, and even your JPEG
cleaner failed to help, it sounds very much as if each .jpg file is empty,
i.e. no proper header or image content at all.
I just looked at one of my own plain .jpg files in hex and in the top line
of 16 characters I clearly see "JFIF" in the middle of that line. My
digital camera .jpg files instead say "EXIF" there and below I can clearly
see the camera's Exif data recorded. The bulk of any .jpg is filled with
various characters... certainly not the 00 you are finding.
I assume the CD in question is not dirty or scratched, and other CDs with
JPEG images read OK? I don't recall if you were able to copy the files to
your HD.

| yeah - copied to harddrive with no worries. cd drive works fine too with
other disks. methinks the images in question were hosed during transfer from
stick to cd, or during the photo kiosk's burning the disk. bugger. but
thanks for all the help to everyone.

That sounds about right... avoid such kiosks in future, and simply buy a
bigger memory card.

You could try IsoBuster to recover the files.
http://smart-projects.net/
It's possible the burn process created the corrupt/proprietary
files but also created a 'hidden' file system with the real
files. IsoBuster will let you view any file system on the disc.
Is the kiosk that burnt the disc worth calling?
