I have a few SD cards (4) that my computer will not recognize, as I download data from cards at the end of this field season.
Any suggestions as to why?
Is it possible that the battery issue I mention in my other post might have damaged the cards? All four of these units have at least one battery that now reads a err message in my charger (less than 0.02 volts). Of course I also have quite a number of other units with err reading batteries that don't have damaged SD cards...
Any suggestions as to how I might be able to get into them and get the data off of them, or are they trash now?
This post might help with pertinent background information on my situation.

All the cards I use are Sandisk Extreme 64 G cards, and all 1-2 yrs old.
They were all deployed last year (2021) with no issues.
All cards are set up the same.
All cards are reformatted prior to being loaded in ARU and deployed in the field.
The other ~50 cards are working/recognized fine.
We've seen issues with ADATA cards failing in the field, but not SanDisk Extreme cards. What issue does your computer report? The card may be readable but the file allocation table is corrupted and that's stopping it showing the listing of files. If that's the case, the files are probably recoverable.
