I have just encountered this problem recently. Whenever I try to open my Flash Drives on my laptop, it tells me that "The drive is not formatted and that I need to format" when I do click on format, it says "format cannot be completed" I am honestly lost, this has never happened to me, I have memory sticks of 64mb all the way to 2GB and all of them cannot be opened on my labtop, but on all other computers they do. But the weird thing is that my wireless mouse works, I can still use the printer and the light on the Cruzer lights up. I have searched these forums and tried many of the tips that where given and yet my laptop still cant seem to let me get into my flash drives. Please Help.
