First timer here, so please bear with me. Any help you can offer is MUCH appreciated!

Some of the files on my SD card have changed file extensions and appear corrupted (the modified dates are wonky and the file sizes are off). For example, a file that was formerly IMG_3324.JPG is now MG_3324J.PG, and I can't open, copy, or rename the file. When I try, I receive Error 0x80070570: The file or directory is corrupted and unreadable.

I have gone into Properties>Tools>Check. I receive the following: "We found errors on this drive. To prevent data loss, repair this drive now." However, when I click Repair Drive, I just receive the error, "There was a problem scanning and repairing this drive..."

Most of the files on the SD card are readable and work just fine. I was able to copy them to another location; however, there are about 60 or so corrupted files that I would like to repair (I don't want to lose the pictures!).

Also, any ideas what causes these errors? I want to make sure I don't repeat this in the future :-/

I'm running Windows 10, and the SD card is a Dane-Elec Proline 4GB card.

You can try running an elevated CMD or Powershell window (WindosKey+X) and typing CHKDSK <sd-card-drive-letter>: /F ; but, there is a reasonable chance that the SD card has failed in which case, that won't be able to fix it and you need to buy another SD card.

When I run chkdsk, the output is below.

Does this mean I can't recover those files? Are there other things I can try? I really really don't want to lose them. Any ideas what causes this?

Thanks in advance!

You can try a data recovery tool that is designed to find JPG images by their signature (its at the beginning of each JPG); but, if that doesn't do it, you should format the sdcard and move on.
http://www.datarescue.com/photorescue/ (Use the wizard and its a free trial that you only need to buy if it does what you need)
