I too purchased File Scavanager and think I've gotten my money back several times over. It has recovered content from crashed drives, reformatted memory cards, etc.

One quirk I've noticed though is that Canon Raw (.CR2) files recovered from a formatted card show up with a .TIF extension. The file size is about right (21MB), and LightRoom seeems to be able to recover them, but it does seem a bit weird that the extension is off. Maybe it's guessing an extension in these cases?

Way back when, Canon's "Raw" format was TIFF. Perhaps it retains much of the header structure from those days.

I will be trying out as many of these as need be when I get back home. Shot the first half of a wedding on my card and only 195 photos are on the card. It looks like the last file that was saved is corrupt, I can only see half of the photo no matter where I view it. From speaking with some people it sounds like that one corrupt file may be preventing me from seeing the rest.

Here is my thread explaining what happened and how:

If anyone else can offer any help at all I will love you forever!

Read through all the posts and tried several programs......perhaps there is a newer program out that might help.

I reformatted my Sandisk and used the card for more images.......RAW format...and so far the programs for recovery are only finding the new images......anyone know of a program that might recover images from previous format?

Thanks for any help!!

The action of reusing the card should probably not have been done because the possibility of an over write situation is high making some images unrecoverable.

Avira Unerase Personal is also a good & lightweight data recovery software, moreover it's free AFAIK.

Hopefully I am posting in the right spot..
Have Canon 6D, used a Lexar Pro 1000x 16gb card while in Florida this past week. Shot pics, reviewed them on camera...looked great. Drive home to VB, turn on camera..Bamm..Cannot read card.
Have downloaded most of the links here, have tried the tape on the write lock slot on side of card....nada.
Windows says the directory name is invalid.
I have gotten it to come up and say the card needs to be formatted.
Tried that with windows and SDformatter. No luck. Says it cannot format.
Have gone through CMD to release or clear the write protect and in DOS it says its clear....But try it in windows and it says still write protected.
Run everything as Administrator...No luck.
Tried ZAR-X, Rescue Pro, DDR Memory Card Recovery etc.
Just cant get past the write protect issue to try anything else.
Any suggestions would be appreciated!

I needed to recover files from a CF card for a Canon 7D Mk II that I had prematurely formatted.

Image Rescue 5 and Recuva all managed the jpg's, but not the CR2
PhotoRec successfully recovered everything.

I did not loose or delete files but can’t open them, on my camera it comes up with a ? But I see the metadata, it’s a raw canon file any ideas? Canon told me I used a larger sd card than the size recommend and that is why. These are of the bride with her family at her wedding so if I can’t open I am gonna have to photoshop something
HELP Dana
***************
Dear Dana Coplin,

Thank you for contacting Canon product support. My name is Mariah and I'd be happy to assist you. I understand you are unable to view or edit the last 30 CR2 images out of the 350 images.

Based on the information provided, it sounds like the memory card had issue writing the data to the memory card. Can you please confirm the following in your response to this email to further isolate the issue.

1. What kind of memory card did you use? It is recommended to use between a Class 6 to 10 memory card with the minimum writing speed of 90 MB/s (size 16 GB and higher). micro SD HC 10 128GB

2. Did you format the memory card in-camera before use (note formatting the card will erase all previous data recorded on the memory card)? yes

3. To confirm, you are unable to view the last 30 images in-camera upon review? yes, unable to view they come up as a "?"

4. You mentioned you exported the images to your Mac computer, did you use Canon EOS Utility or a card reader to transfer the images? I did use the card slot on my iMac and tried by connecting my camera to the computer

5. Once the images were on your computer, you also mentioned you opened the images using Canon and Adobe editing software. Can you confirm the version of Canon Digital Photo Professional software you currently are running? 4.8.30.0

We look forward to your response.

Thank you for choosing Canon.

Sincerely,

Mariah
Technical Support Representative

Dear Dana Coplin,

Thank you for your reply.

It can use the card that you have inserted, but does not format the data on the card above 32GB and this is possibly where the corrupt files were stored.

Try using a card within the limitations of this camera and format the card before using it.

Please let us know if we can be of any further assistance.

Thank you for choosing Canon.

Sincerely,

Trevis
Technical Support Representative
