SD Card Corruption Recovery - Help!

I have had a SandDisk microSD card in my android phone for I don’t know how long. In fact, I’m certain it was in my previous phone before my current one - which I’ve had now for nearly 3 years.

A couple of weeks ago I had a notification on my phone saying the SD card was unsupported, my phone then advised that I formatted the card… Problem is, I don’t want to do that and it was working previously. So why is it unsupported all of a sudden?

I imagine it has somehow become corrupted and now unreadable.

I’ve only just had an opportunity to try to fix this, so the first thing I tried was an SD card repair app for android. I couldn’t proceed with this because when I tried to select the SD card through the app, my phone popped up saying I need to format it first.

So I removed it from my phone and put it into my laptop. It doesn’t appear in File Explorer.

After doing some Googling, I checked in Disk Management. Here, I can see the SD card and it already has a letter assigned to it. It still doesn’t appear in File Explorer. I even changed the assigned letter to see if that would fix it. It doesn’t.

My next step was to run chkdsk. If I specify the drive name that I can see in Disk Management, e.g “chkdsk t: /f” I get the error “Cannot open volume for direct access.” I have Googled this too, but can’t find a solution that works for me.

My last step was to download some data recovery software, with the intention of recovering the data from the card and then formatting it.

My problem now is, after trying 2 different programs (Disk Drill and EaseUS Data Recovery Wizard), neither of them ‘see’ the card - so I am unable to even recover what is on there before formatting it.

So, before I resign myself to losing whatever I have saved on there, I was hoping someone may have some sort of solution. At this point, I’d just like to recover the files from the card and format it.

Any ideas how?
