If you don't unmount the 160 GB hard drive and remove the fstab entry,
the only thing that will happen after you replace it with the new 500
GB HDD will be that at boot time you will see an error regarding the
fact that the system cannot find the hard drive designated by the UUID
that the small HDD had.

Of course, that's not a problem. Once it boots up, just replace the
old UUID with the one for the 500 GB HDD. Supposing this new hard
drive is already formatted and it already has 1 partition which is
seen as /dev/sdc1, run

sudo vol_id -u /dev/sdc1

and you'll get the new UUID that you need to replace in /etc/fstab.
Then (if the file system on this hard drive is the same as the one the
old one had) run sudo mount -a and you're done.

However, if the new drive is not formatted and partitioned, you need
to do that first before editing fstab.
