secondary hard drive sometimes mounted to wrong location?

  • 772

So i edited the /etc/fstab file, and added this line

/dev/sdb1       /media/additionaldrive1 ext4 defaults   0       2

and most times, my hard drive is there waiting for me in the right location. but sometimes, and I'm not sure if i'ts at boot up, or sometimes afterwards, since I generally don't need to the use the drive immediately after boot up, I find the drive not at /media/addtionaldrive1, but at some seemingly random address of "62ae4915-ee29-414e-a684-fc700064d952"

This is annoying as it breaks file references to that drive (it has my virtual machine images). Any idea what the problem is? Reboot generally solves, it's not a very nice solution though.

edit:here is the fstab file:

proc            /proc           proc    nodev,noexec,nosuid 0       0
/dev/sda1       /               ext4    errors=remount-ro 0       1
/dev/sda5       none            swap    sw              0       0
/dev/sdb1       /media/additionaldrive1 ext4 defaults   0       2
mount

    You can prevent this from happening by using UUID in place of device paths.

    Your fstab should look something like

        # /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    nodev,noexec,nosuid 0       0
# / was on /dev/sda1 during installation
UUID=60db2d35-5065-476c-9396-92e8754dd613 /               ext4    errors=remount-ro 0       1
# /home was on /dev/sda3 during installation
UUID=66d44124-3c90-4e42-8d1a-eb8f84350b4b /home           ext4    defaults        0       2
# swap was on /dev/sda2 during installation
UUID=4bd642b2-bff1-42cf-a013-f30c592cadc9 none            swap    sw              0       0
