USB drive not showing up in file explorer

Hi 

The laptop makes usual ding noise when the USB drive is added but there is no option to open the files from File Explorer.

I've done some research and tried various things - restart, uninstalling drivers etc and have found myself on the Event Viewer page for the USB drive. 

The following is displayed:

Device settings for USBSTOR\Disk&Ven_SanDisk&Prod_Cruzer_Blade&Rev_1.00\04016924101322110935&0 were not migrated from previous OS installation due to partial or ambiguous device match.

I'm thinking this is the problem?? But how do I fix it? 

Many thanks in advance for any help
