I use the Lexor 8G flash drive. Had it for quite a while and at some point swapped it from my Toshiba laptop to a MAC. It worked fine. But now when I plug it back into my Toshiba it just flashes and is inaccessible. The MAC is with my EX and I'll never see it again (or her).I have information that is important to me on the drive. How can I retrieve it?
