You could try this ...I have a 64gb usb stick which was only sowing as 32gb. I followed some advice from google to fix this problem & now the usb drive (f) is showing as "the directory name is invalid" I`ve tried changing the directory name but nothing happened. Have i killed this usb?
Plug in the usb
Open 'This PC' to see all your drives
Make the 'This PC' window smaller on your desktop screen so you can see other files
Then drag a photo or some small file across to the usb drive
This should copy the file to the usb so then have a look and see if it is there.
If it is you could then try a 'format' on the usb drive and probably have the option to rename the drive.
