as said in the title first of all i connected a usb key (ntfs formatted) with data in it, on ubuntu 12.04, after i disconnected it i was no more able to access the usb key neither from windows nor from ubuntu 12.04. The system asks me to format my usb key Just now i connected a hard drive ntfs formatted with data in it to ubuntu 12.04. I ejected correctly the hard drive and connected it to windows, and the system asks me to format my hard drive? same as the usb key Can someone help me please ? Would really appreciate!
