[ubuntu netbook remix] Mounting Issues

[osieorb18]

I recently had an issue with my external hard drive after I shut down my netbook without unmounting it-- it wouldn't mount. To fix this I inserted this line:

/dev/sdb1 / ntfs-3g force 0 0

into my /etc/fstab file.
Now when I'm trying to mount my MicroSD card through a MicroSD to USB adapter, it says "You are not privileged to mount this volume." and when I try to mount it in terminal:

>> sudo mount /dev/sdb1
NTFS signature is missing.
Failed to mount '/dev/sdb1': Invalid argument
The device '/dev/sdb1' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?

I've also been having to mount the external hard drive as root using 'sudo mount /dev/sdb1' if I want to mount it.

What do I do to get drives to automount again?

Well, the MicroSD card is likely a FAT32 partition. Since the /dev assignment varies between plugins and reboots, it's being assigned to /dev/sdb1, whereupon your system wants to mount it as NTFS.

Instead, mount by Label or UUID.

You should mount partition in /media/mount_point or any other location instead of /.

sudo mkdir /media/sdb1

Mount partition at /media/sdb1 instead of /.
