Sandisk Cruzer Edge memory stick error?

Sandisk Cruzer Edge memory stick error?

Hi I have a new Sandisk Cruzer Edge memory stick (8gb) and on first use it worked perfectly. The drive shows up on my computer as Removable Disk (G:)
However since the initial use of my memory stick I cannot read the files. I’ve tried plenty of different computers and I cannot copy any new files onto it either. When I try to do so an error message saying “cannot find the specified file. Make sure you specify the correct path and filename.”
I’ve tried dragging files, c&p them and saving directly from the program to the memory stick. None of these actions are working.
After a quick search on google i’ve found other people have had this issue, but I couldn’t find any solutions.

Anyone have any suggestions? Thanks for any help!
