Memory stick not working

Try to connect it in a different USB port. Also connect it to a different PC. Check if that works - thanks!!

Thanks for your response its not working on any pc. I just tried other memory sticks and they are working fine. The memory stick is wobbly, i think its broken

So maybe its time to buy a new USB Flash Drive!!!

This is going to sound dumb, but i have very important documents i need to retrieve

Connect your USB drive to PC and see if it appears in BIOS.
Also check if it shows in Disk Management (Right Click on Computer >> Manage >> Disk Management)

It didn't show in disc management. I've opened it up and used a slim diary to wedge it. It was a contact problem, the soldering is broken. I've managed to copy the file i need. Thanks for your help and response, cos I was almost going bunkers

All is well that ends well. Good thing you got your files back!!!
