nacoly's solution is easier.  And doesn't require loosing all the files on the drive.

Re: SanDisk Extreme USB 3.0 (64GB) Flash Drive not working

My sandisk ultra usb 3.0 screws up my excel save function. After saving a file to my sandisk I cannot then save the same file to my computer. Gives some unhelpful message. Any ideas?

"Any ideas?"

 

Save the file to the computer 1st than save it to the flash drive.  Smiley Wink

I have  SanDisk Extreme USB 3.0 (64GB)  but when i connect it to my PC it says 31.9 free of 31.9 so what happened to the other 32gb?

Is this a new drive?  If so I would say it's a counterfeit.

Counterfeits come in wrappers also.  That's how they look real.

 

Have you looked at the drive using Disk Management?
