Your trying to mount an Logical Volume as an Partition.

Did you do this manually? Post the command string you used.

Have a look at this guide:

Yes, it was done manually using mount command.

Since you haven't posted any info as asked, its not easy to guide you any further...

As there is no further info here could I take on this thread. I have just loaded Suse 11.1 and it won't mount my external hard drive. There are 4 partitions and formated NTFS. I really need to get to that information urgently. My Windows just kept collapsing which was a WinXP 32bit on a new 64bit comp and it just seemed to be stable. Suse at this present time seems to be the only stable Linux OS I have had on here.

Thats besides the point really I am rambling. I have tried to access a root file fstab as I was told to do in Dolphiine but it just won't allow me to adjust or add to the script.
/dev/sdg4/media/disk ntfs-3g force 0 0
Have you any advice how else I can tackle this as everything else seems to be brilliant - touch wood. Which is not what I normally say!!

External dirves do not require fstab entries to mount. This is done by hal/udev/desktop. The external partitions should mount in /media directory. Have a look with Dolphin.

Additionally, from a console, type 'mount' to see all mounted partitions (including the hal-mounted ones).

I agree that you should not need a fstab entry for an external drive. Though, you might need to force a partition that was not unmounted cleanly, as HAL may refuse to do this on its own. This can be done at the command line. To list available partitions, use fdisk (as the superuser/root)...

fdisk -l

(that's FDISK -L in lower case)
After you know what partition you are trying to mount, you can use ntfs-3g to gain access to the drive (this is what mount should be calling anyway).
Simply type mount to see if it's already mounted and where. If not, then try this...

mkdir /media/ntfs1

ntfs-3g /dev/(device) /media/ntfs1 -o force,rw,umask=0

That should give you full access to that partition... repeat with other partitions as necessary. Remember to manually umount the partitions before unplugging the drive.

You posted exactly the same Guide as I did..
Kinda pointless
