While trying to mount my hard drive to copy all the necessary data from my broken drive to this one, I got an error saying:

# mount -t ntfs /dev/sda1 /mnt/dominik/
fuse: mount failed: Device or resource busy

This is my fdisk -l if that helps.

# fdisk -l
Disk /dev/sda: 640.1 GB, 640135028736 bytes
255 heads, 63 sectors/track, 77825 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x70000000
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1       77826   625130496    7  HPFS/NTFS

And just to let you know I can see this partition in Computer but when I try to access it I get this error

I suspect that /dev/sda1 is already mounted under /media/ACER. Nautilus automatically mounts partitions when selecting it on the left side. You cannot mount a partition multiple times (leaving out --bind mounts).

Try doing mount -l to see what is already mounted – Col Aug 14 '11 at 14:49
Acer is /dev/sdb1 - it's a different hard drive. – Patryk Aug 14 '11 at 14:53
So what is the solution to this issue?? You did not tell! – Hanynowsky Nov 13 '11 at 2:14
@Mediterran81 The solution is using the old mount point OR unmounting the old one. If you open a terminal you can get a list of mounted filesystems by running mount without arguments. – Lekensteyn Nov 13 '11 at 10:02
Ok, thanks, that is logical. It just happened I did not understand why the system was unable to overwrite infos about the same mounting point. Actually, I uncommented the line corresponding to the External Drive that matters, in fstab file (using dynamic mounting instead of static one) and everything is back to normal! Thanks for the confirmation :) – Hanynowsky Nov 14 '11 at 0:12

Solve for me :

sudo apt-get purge multipath-tools

say yes


sudo reboot

If you had the USB drive connected before you booted try disconnecting it and reconnecting to the booted system and it should auto mount.
