Trying to recover images from SanDisk

I am desperately trying to recover images that have been deleted off of a SanDisk card. I formatted the card so I realize the chances are slim. I have no idea how the images were moved off of my Mac, but they were and LR5 cannot locate them. I had done a back up and have searched and searched, so I'm left to think that one of my kids may have wacked the keyboard and done something unintentionally.

So - on a separate Dell laptop I installed Recuva. I inserted 3 different SanDisk cards as I don't know which on these certain images were on. Two of them came up with nothing, the third told me that 455 files were found ( odd since I can only shoot 399 on the card ) These files were of "excellent" status except when I tried to recover them I get the message that "The volume for a file has been externally altered so that the opened file is no longer valid"

Is there anyone that can help me?

TIA K

Hi EastCocean, and welcome to the forum.

That error has appeared on here quite a number of times before and it seems to be some kind of issue with Windows rather than something caused by Recuva.

Even googling that error and researching through many of the hits, I can't find any one satisfactory explanation as to why it appears in your situation, and has appeared for others recovering files.

I could say it shows that the files, although displaying "excellent" in status, are still corrupted somehow, but I couldn't say that with any conviction as it's an error which appears in many different scenarios, and many having nothing to do with file recovery.

Some of the other guys have come across this before and may know something I don't and and may therefore have a more positive answer for you, but just in case they don't, I thought I would give you at least a reply if not the one you were hoping for.

All I can suggest is to try some other freeware recovery programs just to find out as to whether you'll get the same result.

Some alternatives mentioned in this previous post ...

... and in the meantime maybe one of the guys may have a better answer for you.
