Hi, I can't mount my external hard drive anymore. I used to be able to mount it. I backed up my website files on this external hard drive.

Now for some reasons I am getting an error message when trying to mount but I do see the device being seen by ubuntu. Just won't mount.

I ran dmesg in the terminal and this is what I get :



[ 367.430226] JBD: no valid journal superblock found
[ 367.430249] EXT3-fs: error loading journal.
[ 752.919641] JBD: no valid journal superblock found
[ 752.919662] EXT3-fs: error loading journal.
[ 1166.500023] JBD: no valid journal superblock found

[ 1326.665064] JBD: no valid journal superblock found
[ 1326.665085] EXT3-fs: error loading journal.
[ 1361.178262] JBD: no valid journal superblock found
[ 1361.178286] EXT3-fs: error loading journal.
[ 1404.740989] JBD: no valid journal superblock found
[ 1404.741010] EXT3-fs: error loading journal.


I would get an error message when trying to mount the drive. It would say something along the lines like : mount: wrong fs type bad superblock on /dev/sdc5 missing codepage or helping program or other error then is says to type in dmesg in terminal for descriptive details to errors.

that is what I get. I think the permissions might be messed up or something not fully sure.

What should I do to fix this? I need to backup new work done on my site.

The external hard drive is a usb drive and has the file system of EX3 linux type.

if there are errors on the drive it will either not mount or will mount in readonly mode. if it's fat32 formatted, run dosfsck on it. i forget the exact option, i think it's something like
dosfsck /mnt/sdf1 -a

No it's not fat32 nore ntfs formated. It's formatted with linux file system the EX3 file system format.

do you think I can reformat the external hard drive? I mean I can do that and just back up what I have right now.

If that's the best method right now then how do I reformat it?

Do a fdsk?
