Badly corrupted MicroSD Card

Hello

I have a SanDisk Ultra 128gb MicroSD card that has become badly corrupted. I used it with my phone and it has over 3 years of photos stored onto it that I have not backed up anywhere else. The card became very corrupted, and I am struggling to get data off of it. This is the output I got from the command prompt when trying to scan it:

The type of the file system is exFAT.
Windows is verifying files and folders...
Corruption was found while examining the volume bitmap.
The disk does not have enough space to replace bad clusters
detected in file \Download of name 1.
Corruption was found while examining files in directory \ (18).
I cannot move, copy, or delete anything on the card. I am still able to see the file directory and files, however. I've tried backing up the card using Windows pre-installed backup software, that failed. I tried using imaging software to create an image of the card, this also failed. I've tried using data recovery software Recuva, this was able to recover some files, but mostly failed. I have only been semi-successful in copying small batches of files from the card.

The biggest problem I'm having with the card is that it will not stay connected to the computer. Many processes I have tried have all failed because the card ejects itself from the computer while the processes are running. Recuva can't scan past 955 files before the card ejects itself. It does this also while I am trying to copy things in small batches.

I can also not reformat the card. This has failed both on my phone and on the computer.

I am desperate to recover these photos, is there anything that can still be done? So far I am at a roadblock with this, and it seems that there is almost nothing that can be done, though I'm hoping I'm wrong.

I appreciate any input I receive.
 
I absolutely hate reading posts such as yours but beating you up for not backing up data won't make you feel any worse.

I suggest taking the strain off the card for a few days and go back in to try to take small bites at any one time. Also, the card might feel more at home in a Linux system.

I have to say I don't see a decent result but I have my fingners crossed for you.
 
I haven''t used it but it's unlikely RealBeast would recommend something if it goes against what you seek to achieve.

However, reading the link, I remembered the possibility of your problem being Write Protect. Can you check that and undo it if it is in that state?

There's a Windows Registry tweak that can help but I'm in a Linux machine at the moment so I can't find the key.

No, but it also may just not work.

I've used it on a number of occasions on external/internal HDDs but not on a microSDcard and it worked well in most instances. It is somewhat encouraging that Recuva even recognized the card. GLTU

Is there write protection written into the card? If so then i'll try this.

Okay, I will try this.

Thanks to everyone for your helpful replies!

Okay,

I tried using the EaseUS Partition Master and followed the guide. I can't check the partition, strangely that option isn't available for the card.

When attempting to format it, it unmounted itself again. This has been the biggest problem - the card will not stay mounted in any operation I have tried.

I also tried removing Write Protecting by editing the registry key. This also hasn't changed the state of my card.

The files are still present on the card.

Does anyone have any ideas?
