SD card - no partition found

#1 Post by totallybree » 12 Sep 2017, 18:07

Hi there!

I'm trying to a recover an SD card that was in my phone that just suddenly stopped working. When I run testdisk, there's no partition found. I've tried Deeper Scan and got the same. When I tried Advanced, I just see a message that says no partition available. Can anyone help? Here's what I see on the log:

The log goes on like this forever.

I'd really appreciate any help! Thanks!

CRC errors are hardware errors. You need to contact a data recovery company.
