Ubuntu – Ubuntu 12.04 stopped suddenly to recognize all usb storage.


Storage gets listed in lsub but is not mounted by nautilus. I tried 2 different devices: a usb stick and an external HDD. usb mouse on same port works fine. is there anyway to force mount it?

my /etc/fstab file,

# <file system> <mount point> <type> <options> <dump> <pass> 
proc /proc proc nodev,noexec,nosuid 0 0 
# / was on /dev/sda6 during installation 
UUID=f1fd50a1-7a61-413c-9332-4bf94cb3321c / ext4 errors=remount-ro 0 1 
# swap was on /dev/sda7 during installation 
UUID=4d1ab5a9-4477-4222-b6d0-cdc5818fc55e none swap sw 0 0

I'm not sure why Nautilus isn't showing the drives. It looks like they're showing up as sdb, so you can attempt to force mount the partitions by using sdb1, sdb2, etc. Assuming you're mounting the first partition, first make a folder somewhere (I'll use /mnt/sdb1 for this example), then run:

sudo mount /dev/sdb1 /mnt/sdb1

Then cd into /mnt/sdb1 and see if the files are showing up. Any error you get will help you diagnose the real problem. I would normally guess here that the filesystem might be corrupt, but that's unlikely to be true for two separate drives.
