Where have my photos gone? Help please!
Discussion
I took a friend to Mercedes world in Weybridge today and took about 20 pictures with my Canon 400D before the battery ran out and so I swapped to my backup 300D and probably took another 20 or so. I've just got back and all pictures have gone. There are about 140 photos still on one card from before but none of the ones I took today are there. The other card from the 300D is blank. I had viewed the photos on both cameras before coming home.
Somebody please, tell me what I'm doing wrong. I'm fairly sure I didn't turn off the cameras while the CF cards were being written to.

Are you looking at the card via a card-reader or on a camera ?
Are there multiple folders on the card ?
What make is the card ?
The camera should be saving the images to the card as it takes them, i.e. about 1 second after pressing the shutter. Unless you were shooting bursts of multiple images, i would imagine it would be hard to turn off the camera before it had chance to write them !
Hope you manage to find them

Both cards are 2 gig sandisk cf. I have found a piece of software that has managed to recover the pictures but I still wonder why both cards corrupted in the first place.
But how were you reading the cards in the first place?I have a Canon Pro1 and a 400D which both use CF cards. I often use Zoombrowser asa quick viewer to see what there is before the first download. The version of Zoombrowser I am using - not the original release version with the PRo1 - understands both the Pro1 .crw files and the 400D .cr2 files.
If I put a card with 400D images in the Pro1 it thinks it is empty, which is not unreasonable. It won't know about the cr2 format.
If I put the card in a card reader everything is (usually) accessible.
I think it would be wise to avoid using a card 'live' across two cameras for a number of reasons, not the least of which is how the folder and file numbering defaults are set up and what other 'system' rules are set that might be different from body to body.
Sharing the cards between bodies with formatting after download and before use should be fine.
You should be able to work without image loss, as you have found, but absent some exhaustive testing there will always be some element of risk at the back of your mind.
Others may have more suggestions.

I am using just a cheap USB card reader. The recovery software I downloaded managed to extract 600+ photos from one of the cards, most of those which had been deleted on purpose. It's nice to know I can recover any pictures accidentally deleted.
However, the pictures I took yesterday were mostly corrupted but I did mange to retrieve a few.
That's probably good advice regarding the formatting and I have now reformatted the cards. Hopefully, this will clear any problematic areas.
