I _really_ need your help !

The hard disk where I put my archive of thousands of pictures that I've
taken, recently acted up. The entire FAT screwed, and all the picture
files that are stored in it, CAN NOT be retrieved !!

I ran chkdsk on the drive and it ended up with thousands of thousands
of file****.chk files under several FOUND.00x directories.

The picture files include TIFF files - (*.tif or *.tiff), JPEG files -
(*.jpg or *.jpe or *.jpeg), bitmap files - (*.bmp), and some GIF files.

Now I am getting _REALLY_ desperate !!!

Is there any program or utility that can automatically scan these
"*.chk" files, identify them, and then convert the files back into
their original format, such as *.JPG or *.TIF or *.BMP ?

I fully understand that some of the files are gone forever, but I need
to find a way to rescue as many of them as possible.

Can you help, please ?

If you know of any utility, be it freeware, shareware, or
commercial_ware, that can scan the *.chk files, or even scanning the
disk itself, and then retrieve whatever picture file it finds, please
tell me where and/or how to obtain/buy/download that utility.

I am using Windows, but I can use DOS or Linux to access the disk.

Please, please help !!!

Thank you.

I'm sure there might be a Windows tool to help out but none I can
think of at the moment.
Regarding Linux there are two command line tools you can probably
use, file(1) and identify(1).

file relies on a good magic file (say /etc/magic) to work
properly. In XP I have Services For Unix and just tried its file
utility on a couple of image files. Both png and bmp came up as
just "data" because the magic file isn't well-populated.
Results were better in Linux.

identify, part of the ImageMagick package, is a much better utility.

You could probably do a simple shell deal on the .chk files and
output the results to a text file to see what might be retrievable.
Something like:

for files in *.chk; do
  identify $files > fiximages.txt
done

or something to that effect.
I'm sure others can give info on what to do after that using
the shell to copy/rename a bunch of properly identified files
to images.
It'll take some time but a lot faster than trying to ID each
one individually.

Maybe post to one of the Linux newsgroups or comp.unix.shell(s).

I'm copying the thing that you've posted, and once I'm offline, I'll
boot up Linux and try your way.

Thanks !!

If you think each CHK file is one image (that's quite possible for a large
partition) then this image utility has an 'identify and rename' function:

See if this tool will help you

Or look into SpinRite.  Do a google on that one.

Yes, I did, but for those thousands of pictures that causes my head to
suffer massive hairloss, not yet backuped.
spamharvestor@gmail.com - 28 Sep 2005 04:40 GMT
These are recent photos, the oldest was about 4 week old.

I do burn the pictures onto the discs, however, I often collected
enough, as in hundreds-of-megabytes, before I do the burning. These
recent photos aren't yet sufficient to fill a CD.

I know, it's my fault !!

But anyway, thank you and all for your help !!!!!

I hope that you will now use multisession when burning so you can top up
cd's.

Easy. Format the dodgy disk and then just restore the pix from your backup.
What's a backup, I'm sure I hear you asking ... begging ... imploring ...
wishing.....

If you have more than a hundred pictures without secure copies thereof then
you are, at best, a fool.
If you have, as you say, thousands, then words fail me.
spamharvestor@gmail.com - 28 Sep 2005 04:04 GMT
Yes, I have backups, but those thousands of files on my disk are not
yet backuped !

Oooooooops !

and that's why I'm tearing my hair out, bunch by bunch right now !!

Try this to identify files based on their content (similar principle as
Limux' file) :

Or via a web-interface, one file at a time :

Greetings,

I have used a program that works pretty well in finding and recapturing
images that might have been deleted, sent to the trash or lost on a HD.
Take a look at Image Recall. It should be on the web.

http://www.imagerecall.com/

You can download a test version that might save you.  I like the
program and have saved many a card and in one instance not too
different from yours - content on a HD.

Not a suggestion of Kodak

Talk to you soon.

Hello all,

First of all, I need to thank all of you who have helped me so much !

My disk conked, and thousands of the picture files in it got trapped in
it. So I asked for help here and you guys have been so generous and
kind-heartedly helped me finding ways to retrieve the files.

Thanks again !!

Now, I need your help again. But this time, it's a little bit
different. You see, many of the "retrieved files" dug out with ZAR
(zero assumption recovery), chkdsk, unchk and so on, have file size in
the tens of megabyte.

For example, here is one *.chk file with 35,079,680 bytes, and upon
checking I found out that it was supposed to be a JPEG file. Using
graphic software, I got the information below:

    Packed Size:    35,079,680 bytes    (33.4 MB)
    Unpacked Size:    471,600 bytes    (460 KB)
    Compression:    -7338 percent

This shows one thing - a JPEG file that was 471,600 bytes in length
which is carrying an excess of 34,582,080 of junk bytes, and in order
to get the original file back, I have to find a way to get rid of all
the excess "fat".

    That's a lot of "fat" to be trimmed - from 33.4 MB back to 460 KB !

This is just one example, and there are more than 60 thousands of such
files, all waiting to be slimmed down.

    There lies my problem !

The thought of manually slimming down 60+ thousands of files is a task
too daunting for me to venture.

    So far, I've done 400 of them manually, but that is but a little drop
in the bucket !

Therefore, I need you help. I need to know if there is any utlity that
can retrieve the "true" picture file, whether they be JPEG, GIF, PNG,
BMP or TIFF. I really am looking for a utility that can automate the
process I mention above - to get rid of the "excess bytes" so to return
the picture file to its original size.

I don't care if the utility is a shareware, freeware or commercial
ware, as long as it can help me.

If you know of such utility that can do that, especially if it can do
batch process of thousands of file in one go, please tell me.

I appreciate all your help so far, and I apologize for needing more of
you assistance.

Anyway, many thanks to all of you !!!
