nacoly's solution is easier. And doesn't require loosing all the files on the drive.
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?
Save the file to the computer 1st than save it to the flash drive.
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?
Did you reformat it?
Yes when it showed as 31.9 and no change
Is this a new drive? If so I would say it's a counterfeit.
