Try re-installing your USB drivers and re-connecting you pen drive. Do you eject your pen drive properly each time you connect it? Have you tried the Pend drive in another machine or another USB port?

Thnk u for the reply
I do eject my pen drive properly (safely remove ) , like i said 2 of the ports are bad... the same pen drive works on the third USB

will come back to u as soon as i uninstall the drivers... most probably tomorrow
