I formatted it but realized it immediately and so put it aside and not used it again so far.ThanksDid you format, or just erase?
If formatted, you likely will have a more difficult time of trying to recover anything. With a simple erase, you often just wipe entries from the 'directory' tables of the media, but with format, it can often happen that the full disk is overwritten or "zero'ed" out....with data physically overwritten.
I know this is largely how regular hard drives work...not sure with memory cards like CF ones, but I think this is likely how they work too...if formatted, you may be SOL on this one....
Erased files can usually be resurrected, as that it is only their catalog entry of where on the disk the data/file is located...the data is actually still there. Not so much with most formatting actions.
Thanks!PhotoRec, https://www.cgsecurity.org/wiki/PhotoRec , it's free and as powerful as it gets, along with the even grander Test Disk.
I once recovered files for a woman off a reformatted and used SD card, it recovered images years old from two older cameras as well as all her current 'lost' images.
HiThe terms format or erase confuse people, some software, like the lexar card software uses erase to write all zeros to the card which basically makes files unrecoverable unless you are NSA. It takes a very long time to run. Format will let you recover files but you may lose the original file name. A low level format is more serious, the data is there, but the indexes to the files are gone.
There are lots of software recovery programs, Lexar software is no longer available for download after selling the business to a Chinese company, but Sandisk Rescue Pro deluxe is very good and available here. It works for various card brands.

I have a stack of free keys for it that come when I purchase a Sandisk Card(free for 1 year). Beware of sites trying to fool you about this, get it from the official site. you can link to it from the Sandisk site. Its available for windows or mac.
Send me a message and I'll photocopy the key card and send it to you. It has a unique serial number and can only be used once. The key is for Sandisk Rescue Pro Deluxe.
Thanks for your diligence and effort!I did one more try with both cr3 and jpg files written to the same card, then formatted. This time, it found 2 jpg files, apparently the one saved to jpg and the one embedded in the cr3 file. The card was first low level erased.
Its a 128 gb card, so I'm going to retry with a small card, since it takes a hour to search a large card.
UPDATE: Same results, does not find CR3 but finds the jpg thumbnail that is embedded in the .cr3 file and it finds the full jpeg file.
The .cr3 is in the family of .mov files and they have been mentioned in the PhotoRec forums. https://forum.cgsecurity.org/phpBB3/viewtopic.php?f=7&t=8364One final try with Rescue Pro Deluxe using the recover all files option. It did find the .cr3 file and the embedded jpg, but could not recognize the cr3 and gave it a m4v extension and my pc called it a pdf file. I changed the extension to .cr3 and opened it in lightroom and it was the correct image.
The software needs a update. I'll send them a message.
