View Full Version : [lubuntu] failure to mount USB drives

April 7th, 2011, 01:40 AM
I'm having a moderate annoyance with a USB thumb drive. It fails to mount automatically, so every time I want to use it I have to go through the command line and do that manually. I have another external hard drive which mounts automatically just fine -- it's particular to this thumb drive.

When I try to use the Disk Utility and hit the "Mount" button, I get the following error message:

Error mounting: mount exited with exit code 1: helper failed with:
mount: according to mtab, /dev/sda1 is already mounted on /
mount failed

If it helps, here's my fstab file:

# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
/dev/sdb1 / ext4 errors=remount-ro 0 1
# swap was on /dev/sdb5 during installation
UUID=36d9165e-2290-4df0-9672-b962682d563c none swap sw 0 0

The thumb drive is associated with sdb1. My first guess is to delete that line -- maybe fstab is directing it to the wrong mount point. I'm hesitant to monkey around with fstab though, is this what I should be doing?

Try this:

cd /media
sudo mkdir Windows (or whatever you want it to be called)
sudo umount /dev/sdb1
sudo mount.ntfs-3g /dev/sdb1 /media/Windows

Saw the above fix on another thread:


There have been a few people getting your problem sorted out this way...seems its trying to mount over your OS drive /sda1.

Hope it helps
