Hi Dan,
That's a doozy of a first post! ;^) Welcome to Linux!
Personally, I'd forget about the auto-mount issue until you can be sure the
disk is manually mountable and what filesystem (if any) is on the drive. (Walk
before we run.)
You already know that the drive is 'dev/sdb[1]'. Aside: If you're comfortable
with the command-line and its utilities, this is something you can also
discover with an 'fdisk -l' command to list all devices. But be _very_ careful
with 'fdisk' commands (usually used to manipulate the partition table,
possibly corrupting a drive if you get careless!) -- that's an 'ell' not a
'one'!
If the device exists and has a valid filesystem, it should be mount-able (as
'root' user, of course):
mount /dev/sdb1 /mnt
If that fails, try it without the "1". This will attempt to mount a drive
without partitions but with a filesystem (rarer, but possible):
mount /dev/sdb /mnt
If that fails, I suspect there is no filesystem on the drive and you'll need to
cross that bridge next.
If either of those 'mount' commands _succeeds_, you should be able to
determine the filesystem used on the drive like this:
df -hT
That's a 'disk-freespace' command, with the 'h'uman-readable and 'T'ype of
filesystem options.
If these are new drives, they might have no filesystem at all, in which case
you'll want to format the drive(s). If they already have a filesystem (like
NTFS), you'll probably still want to re-format them. By the way, I agree with
the others who suggest use of a filesystem besides NTFS. I cannot recall the
size limitations (e.g. 2TB?) of the various filesystems, but it might need
consideration too.
If you cannot get things working, please be sure to share the output of
any/all of these commands with the folks on this list in your next post.
Hope this helps a bit, initially....
Regards,
Bill Marr
