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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/68824 Title: Ubuntu destroys filesystem on attached USB harddrive! Status in gnome-volume-manager: Invalid Status in linux package in Ubuntu: Incomplete Bug description: I already reported this bug # 68744 But instead of only mounting it multiple times ubuntu edgy has also destroyed the FAT32 filesystem on it, so that all my data are lost. It started to mount the drive over and over again, then I shutdown ubuntu which resulted in "I/O buffer error on /dev/sdb1" and a hangup on shutdown, and then windows checked the filesystem and most of my files were gone. Other linux systems also show the "multiple mount" bug. Please set this to "critical", because destroying data just by plugging in an USB drive (I didn´t change any data on it) isn´t acceptable at all.
