SD card not read by PC

[Sandroid]

I see you tagged tracker-plus , if you have a Tracker+ you could try connecting to it with the Tracker itself.

• Keep the card in the Tracker+
• Connect your Tracker+ via USB to your PC
• Config → USB → Storage

If that works, i suggest you backup all your data first.

Then you can have a look here:

SD contents lost

Aww crap Hopefully you can get lucky trying one of these : On Mac: Try Disk Utility → First Aid (Official User Guide) or something like Disk Drill On Windows: Try chkdsk x: /f . Replace x: with your drive letter (ideally run as administrator) or something like Recuva
