Where is that hard drive?

I don't understand why gparted wouldn't show anything but I'd use mount
anyway.

mount|grep sd

What is the output of "$ mount" ?

This should show up what filesystem it's mounted as which is where I'd
start. If it doesn't show up there, look in /etc/fstab to see a
reference for it in there.

If nothing shows up there, maybe it's not even a separate partition.
Maybe it's just a directory named sda5 in your /media directory?

eg you could type "$ sudo mkdir /media/sdxzy" which would create a
directory in your /media, but it isn't actually another disk/partition,
it's just a directory on your /dev/sda disk.

That's where I'd start anyway...

Not really.

If it's not mounted, and it doesn't appear in /etc/fstab, then it isn't
mounting automatically. If it isn't in any configs like samba or nfs
for sharing, then it must just be a deceptive directory name only.

Try renaming it, keep your system running and see if anything spacks
out. If it does, change it back and you know your culprit. If it
doesn't I'd guess it's redundant.

You aren't running any production type servers or anything on it? Just
a desktop type thing?

Execute:

cd /media/sda5
df .


You'll probably find that it's the same output as

cd /media/
df .

This will show you what file system the directory you are currently in
is mounted on. However, I'm guessing it's just a directory. That's all
mount points are. If you remove the external 300GB ext 3 backup device,
/media/sdd5 will still exist and you could potentially put files there. If
you then mounted your external 300GB ext 3 backup device, you would no
longer be able to access those files. While this sounds odd, it's amazingly
convenient.

When I began to run out of space on the hard disk in my web server, I added
another disk, copied all the files to it, and mounted it on /var/www

dweezil:~> df -k
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda1 13756872 10870008 2188040 84% /
tmpfs 193592 4 193588 1% /dev/shm
/dev/hdb1 10080488 5419548 4148872 57% /var/www

It's just like it's in the /var directory... only it isn't. Not physically.

Ah, then I think it's an empty directory. If you 'ls -l /dev/sd*' you
should see what is going on.

If the line starts with an l it's a link.
If it's a real device it will start with a b.
If it's a directory it will start with a d.
And so if it starts with a d it can be safely removed.
