SanDisk Ultra 32GB MicroSD HC I show as 31MB?



My SanDisk Ultra 32GB MicroSD HC I show as 31MB and sometimes refuse to be recognized. 

It was pulled from my Sony Android phone. 


Any idea how to repair it?


There's no hidden partition. 

Also tried to use FbinstTool to force format it and doesn't help.

If there is no important data, try to reformat again using command prompt.

If it is still not working, I would recommend to re-partition the drive. 

1.Right click on Computer

2.Select Manage>>Storage>Disk Management.

3.Find your drive. If it shows "Unallocated Space", right click and select "New Simple Volume" and create a new partition.

Incase you have important data in your MicroSD, still format the SD card and use a recovery software to retrieve them.
