Then reviewing in post, corrupt RAWs, 2000+ of them. I'm fuming.

Not Pro-grade, at all.

Guess I need to go back to my Sony Toughs, never had a problem with em. Just 128GB came be limiting.

Are you on Linux now? Have you tried reading the card in a Windows or Mac computer and/or a different card reader? I am trying to figure out how you had so many corrupted files , but the camera never threw up a write error.

As a general, I never leave that many photos sitting on a single card.

MacOS shows the previews don't exist for those files; I checked.

I would try a different reader

Thanks, will try.

Edit: Although one of the movies is still "toast", the 2000 files from the 8th of this month, are now showing up with previews on MacOS... Used a different reader. Transferring and crossing fingers...

Nope, they're gone. Good idea though. I'm double grumpy though, they were from my kids field trip to the museum, with my Rokinon 21mm... Ugh. Those really came out good, but never made it obviously.

Weirder...

I'm able to process the RAWs, in camera to JPEG...

?

What gives...

Re: Weirder...

What about transferring the images using wifi or connecting the camera using usb?

Re: Weirder...

Might it be possible to put the problematic card in a twin card camera and synch to a fresh card?

Nothing.

I figured out why I could in-camera process that one; using the other reader I was able to "save" around 1500 shots. Around 450 still remain corrupt which reflects both in camera and transferred along with the movie casualty. The one I converted was one the "saved" shots using the other reader; I just didn't realize the number of shots corrupt shrank as there was still a ton corrupt.

At this point it becomes data recovery to attempt to save the remainder which there's a couple options at my disposal for that...

Actually data cloning from bad to good donor is one means of data recovery. File type scanning is another.

Dang!  Think it's just bad luck?  Or something more ominous?

Which card was it exactly?

Best of luck trying to recover!  The one time I accidentally formatted a card with images left on it, I used Sandisk's Rescue Pro, but I know nothing beyond that.

My thinking was that if PC operating systems are having trouble, but the canon camera operating system is still able to access and edit the files, then it could be used to do the cloning, or at least a file synch operation onto a fresh card which might be recognised by your desktop computer.

Good luck with recovering the data!

Good question and to your point I broke my golden rule of cards: test them first. I didn't run a full zero of the card this round.

Actually data cloning from bad to good donor is one means of data recovery. File type scanning is another.

They're complementary, really.

Step 1 is cloning (or imaging = cloning to file, which I prefer in case of data recovery from memory cards). You clone using a good quality card reader preferably. Depending on physical state of the card you may be able to do this using file recovery software like R-Studio or DMDE. If state is bad (many bad sectors, drive dropping from OS repeatedly) you better use ddrescue.

Then step 2 is put 'patient drive' aside and do file recovery from the 'disk' image using file recovery software.

Depending in state of file system, you do file system based or 'raw' recovery. File system based is always preferred as file system allows us to resolve cluster chains for non contiguous files (for non deleted / lost due to formatting files) and produces original filenames + folder structure.

If file system based recovery produces corrupt files, try raw (signature based recovery) as seemingly corrupt files may be product of corrupt file system. Raw recovery scans for start and end of a file. Fragmented files can not be recovered this way.

But it is of course possible files themselves are corrupt, in which case corrupt files are all that you'll be able to recover. Depending on actual damage it may or may not be possible to repair files.

My personal goto tool for this type of recovery is DMDE, it's my 'daily driver'. Often it is good enough to clone (but I am using professional hardware to handle instability issues), do filesystem based recovery and do basic raw recovery of non fragmented files. I m using pro version of DMDE, but free demo is generous and allows you to recover 4000 files per folder/session).
