This is not a good sign. ls should never return "I/O error"; that usually
means either filesystem problems or hardware problems. After you see
something like that, you should always do "dmesg | tail -n 30" and see if
anything in the output from dmesg has anything like "sdX: unrecoverable error
reading sector 131072".

Not really. As root, you need to create a dir in /mnt/backup/ which is owned
by your user.

When you mount a filesystem on a dir, the mountpoint may or may not change
ownership. Take a look:

workstation:~$ ls -l /mnt
drwxr-xr-x 2 root root 4096 May 9 15:37 bigred
workstation:~$ mount /mnt/bigred
workstation:~$ ls -l /mnt
drwxrwxrwx 8 mhgraham mhgraham 4096 Dec 31 1969 bigred

...bigred is a FAT32 filesystem on a USB device. FAT32 doesn't have
permissions, so they're faked at mount time with a umask of 000 and ownership
of me. If this were an ext3 device, the / of the device would be owned by
root:root by default.

Are you sure this disk is OK?

Check the output of dmesg and see what's going on.

ls -l output is: 1 char for filetype, 9 chars for permissions
(user,group,other), link count (the number of things that are in a directory,
or 1 for non-directories that don't have hard links), user who owns the file,
group who owns the file, size of the file, date, filename.
