after I installed some programs on the usb, I was not allowed to unmount, so I just unplugged the usb stick.
I just read this: Failure to unmount before disconnecting the device can result in loss of data and/or a corrupted file system. There are no exceptions to this rule. Be safe - unmount your drives before disconnecting them! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/68824 Title: Ubuntu destroys filesystem on attached USB harddrive!
