There are a few reasons for that Virus, Pc usb port fault or the pen drive itself scan the drive with a updated AV and check it in another PC see if it works else RMA

Mithun_mrg is exactly right. Check that pendrive in a virus free pc. Then make sure you clean your pc before plugging the pendrive again.
