Following up on the thread about dumb mistakes, this past Friday I negligently formatted the wrong SD card and lost a whole week of bif photos. However, for something different, I am going to post a few pictures in the Nudity section.

Hopefully, you haven't used that card yet and will investigate image recovery software to see how many (if not all) images can recovered.

Hopefully, too, you'll look at your workflow and overall camera behavior. There's no reason to recover / mass delete images until you've (a) unloaded the images, (b) backed-up the images and (c) visually confirmed the successful completion of both items a & b.

You forgot to review the contents before deleting.
Oops.

Good point, make that item (d) review the images on the card again before actually deleting.

I had two of the same kind of cards, and put the wrong one in the camera and reformatted. Stupid, negligent mistake. If I had just deleted the images, they would be recoverable with available software, but since the card was reformatted, I don't think they are..

WAIT! Don't use that reformated SD Card

Quick Plan of Action to Recover Deleted Photos from SD Card

Stop using the SD card!!!
This is important because overwriting the data will make it harder to recover deleted files from it. ...
Scan the SD card with the free trial versions of SD card recovery software. ...
Recover the photos from SD card. ...
Backup the recovered files.

I've been there, done that and gracefully recovered with the help of a downloaded Data Recovery app... Trial Version no charge :)

Any programmer will tell you that "Delete" and or "Format" only toggles a bit or so in the file (not the entire file!).
Too many years writing code... Thank goodness I don't do that madness anymore :)

After using it the first time, I never format an SD card. When I get lots of pictures on it, I'll delete them using the computer, after LR imports them.

If you formatted in the camera, open your browser to google and try: how to recover images from formatted card

Don't buy anything until you've tried all the free ideas in the results set.

I'm not sure what the "format" actually does to the card. I doubt it writes all 1s or 0s to each cell. (A low-level format may do that.) Maybe it just wipes the file allocation table (FAT). Recovery software may be worth a try.

I only format a card when it is new, and that's just for kicks & giggles.
My camera will take a "new" card and do to it what it needs to do. The "unformatted" cards work just fine in my camera. The camera senses what folders are "missing" and creates them.

It doesn't take away the data - just the information on how the data is stored.

Thought so.
Wipes (resets) the FAT table.

The writing of 1s and 0s is only possible with a third party formatting utility, like the free SD Formatter https://www.sdcard.org/downloads/formatter/

Typical devices like cameras will use a quick format which only installs a new File Allocation Table. The files remain on the medium but cannot be accessed without software that is designed to do recover them.

I use SD Formatter regularly to keep the "housekeeping and security stuff" on the cards in order.

My card workflow is simple, and since 2000 I have never lost a file due to overwriting. When I get back from a shoot, or at the end of the day, I will copy the files to my computer (added to my Lightroom catalog), verify that all the files are in the folder, then the backup program I use creates a backup overnight to an external drive. So the following morning I have three copies - on the card(s), the computer and the external drive. When I am done editing my images, which usually happens later that morning, I format the card(s) using SD Formatter.

My workflow is simpler: Stuff the card in the camera, use it, save images to computer, back those images up, delete images on card via computer.
Repeat as needed.
Has worked great for over twenty years.

Installs a new FAT Table? Are you sure it doesn't simply clear the existing table?
Brings up an interesting question: Are the FAT Tables "one size"? or are they expandable with an end of table marker. How would it know how large a "table" to install?
100 files? 1,000 files? And space to accommodate segmented file information?
