"Please enter a disk into the drive" This is the message I get whenever I insert my transcend 1 gb pen drive into the usb socket. Can the Pen drive be reformatted and usable?

Can the Pen drive be reformatted and usable?
Yes, if it isn't damaged. Try the drive in another machine first too.

Hi even I am facing the same problem, I was copying onto my pen drive some data and all of sudden power went off and when I started the machine back from that time my pendrive is giving the error "Please insert a disk into drive f:"
Please help
