Greetings all,

Just wanted to share something that happened to me yesterday and know somewhere, someday it may happen to you.

Went to an event yesterday and shot about 100 pics. Viewed a few in the camera's LCD, no problem. Got back to my computer, took the CF card out, put it in the USB card reader and the PC reported no files. ?? It seemed that the FAT somehow got corrupted. The camera was reporting the right number of images remaining, and the PC was reporting the card as having only about 1/2 it's full capcity. Been there before?

Here's what I did to recover ALL the images:

Put the CF card back in the camera and went to My Computer, found the removable drive (camera) selected Properties, Tools, Error-Checking. I got a warning that it did not have exclusive access to the drive and would I like to schedule a repair the next time the PC was restarted. YES!!!
Rebooted the PC with the camera on and in transfer mode. Scandisk ran, found the FAT error, corrected it and converted the files to lost clusters (or files?). After the PC was rebooted, I went to Windows Explorer, selected removable drive (camera) and found all the files (images) were there, but now renamed as FILE001.CHK, FILE002.CHK, etc. (Lost cluster files and may have been moved into a FOUND sub-folder on the card by the way)

It's OK - they can be converted back. Copy all the CHK files to a folder on your desktop. Go to the folder and double click one. A popup said it was a jpeg with an incorrect file extension - rename? YES!! Now I can view the image in my default image viewer. All the CHK file extensions will need to be renamed to .jpg. The EXIF data is still in place and all is well again. (Batch name utilities can help here).

Remember to put the card back in the camera and use your camera's format function to re-format the card.

Hope this helps anyone in that OH CRAP situation when you think all is lost - it isn't!

(This was done on a Windows 2000P PC if it makes any difference)
