I connected a USB key (NTFS formatted) with data in it, on 12.04, after I disconnected it, I was no longer able to access the USB key neither from Windows nor from Ubuntu. The system asks me to format my USB key.
Just now I connected a hard drive NTFS formatted with data in it to 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?
