Surely it tells you that /dev/sdb1 was
not found in /etc/fstab? If it was found, there shouldn't be a problem.
It therefore sounds like you're trying to mount the device without specifying a mount point (i.e. the directory you want to mount to). Try running "mount /dev/sdb1 /some/directory", e.g. if you wanted to mount to /mnt/external, you'd issue
# mount /dev/sdb1 /mnt/external.
The directory you want to mount to must exist first, so if it does not, create it with mkdir.
You may need to specify the filesystem type (NTFS, FAT, etc), which you would do with
# mount -t ntfs /dev/sdb1 /mnt/external for NTFS and
# mount -t vfat /dev/sdb1 /mnt/external for FAT.
You can add a line to your /etc/fstab so that you can mount the device by just issuing
# mount /dev/sdb1.
This pages explains some stuff about fstab.
SuSE may have some kind of graphical tools to mount stuff, but I've never used SuSE so don't know about these (and the terminal stuff will be common to all distros).
