I believe Photoshop beta corrupted TWO SD cards while in the middle of editing.

Now both sd cards are unreadable and I can not even figure out a fix. I just removed the beta version. But really need to get the pics off both of those sd cards and they are corrupted and my compture will not read them.

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

I'd be interested in your workflow?  It sounds like you were working directly from the SD cards, which is not best practice.

Sandisk used to have a card recovery program, and it got me out of trouble at least once.  I suspect you'd have trouble tracking that down nowadays, but a quick search found this review of alternative recovery apps   If you do decide to go with Recuva, be very careful when installing it.  Read every step of the install process because IME anything that comes from the CC Cleaner site will try to install other apps at the same time.  So do your homework.  I suppose it comes down to how much you want those images.

BTW  it always used to be a good idea to format data cards in the camera, and not in a card reader using your computer.  Obviously don't format the cards till you have got the data off, if that's what you decide to do.

I was working from the sd card. I have never had a problem with that until
now. I have only ever formatted in my camera. I didn't even know you could
format on the computer. I can see the files on the camera so I just ordered
the cord to see if I can retrieve them that way. Thanks for responding.

Debra, you are asking for trouble working that way.  What is the connection between camera and computer?  USB C is probably the safest.  USB-A not so much so.  

Where did you obtain the cable, and how long have you been using it?  Those cables tend to be thin and are inevitably flexed when in use which can lead to beakdown of conductors — especially close to the plugs.  Even with strain relief the excessive flexing will eventually cause the cable to fail.  

What is the socet at the camera end, and does it have a cover?  Perhaps a good illustration of why those systems are unreliable is phone charging.  Have you ever had to clean the socket in your phone because the cable was not making a good contact?  Have you ever had to move the cable a wee bit to make the phone start charging?  Now think of that exact same system, but this time transferring gigerbytes of data, and ask yourself is this really a reliable system.

How do you organise the files when processing them?  Is it Lightroom, Bridge, Finder or File Explorer?  You surely want that to happen at NVMe drive speed and not SD card speed?

I can remember when Windows used to think that the drive the file you were working on was also used as a sort of scratch space.  When you consider that this would have been the earliest, dog slow USB cards and connections, it's now wonder things would suddenly becaome VERY slow.

So please rethink your workflow.  Move all image files to a computer drive, and work on them there.

This is what I am using in my Canon R7.  That's about what the early SSDs could manage. 

This what I upload the image files to using a Sandisk USB-C  card reader.

That's 250MB/s compared to just under 7000MB/s

I think some of the SD cards can manage 300MB/s — I am a bit out of touch, but I don't think by much.
