corryguard I honestly don’t think disk imaging is something you need to worry about in your case. From what you described this sounds like a simple in-camera delete. That’s a pretty clean recovery scenario.
If you go with Disk Drill, just select the SD card from the list of devices adn click Search for Lost Data. You’ll usually see two scan types: Universal Scan and Advanced Camera Recovery.
Since this is a Nikon card, I’d go with Advanced Camera Recovery (its specifically designed for camera media and handles the way cameras write files a bit better). Let the scan finish, preview what it finds, and recover the files to your PC (again not back to the card, this might be important!.)
Now, about disk imaging. people often recommend it in data recovery because
(1) If the card is physically failing, repeated scans can stress it.
(2 ) If you mess something up, you still have the original untouched.
(3) It lets you try multiple tools safely on a copy.
That’s all valid advice in complicated or unstable cases. But in your situation imaging is probably overkill IMO. It adds complexity you don’t really need right now.
