I read about using fsck to repair the superblock, so I unmounted /dev/sdb and got this:
[EMAIL PROTECTED]:~$ sudo fsck -r -t ext3 /dev/sdb fsck 1.40.8 (13-Mar-2008) e2fsck 1.40.8 (13-Mar-2008) fsck.ext3: Superblock invalid, trying backup blocks... fsck.ext3: Bad magic number in super-block while trying to open /dev/sdb The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> That didn't help so I've created question #42774 -- error on booting up mounting an external usb-drive https://bugs.launchpad.net/bugs/97206 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
