use fdisk /dev/hda
then an 'n' will start the process to create the new partition
pressing enter a couple times will accept the default start and stop
'w' will write the table.
A reboot will activate the new partition,
then format it and mount it somewhere you choose
Yes, from your listing above the new one should get the name hda6.

If your system is fragile enough that adding another hard disk will
break it then you have no business running it as a server.
fdisk can be risky if not done right. Running a server without enough
confidence in the hardware to be able to add devices as needed is IMHO
even more risky because you can never make changes when needed, but only
when replacing hardware.
If the system is powered down and does not come back then by your
approach you need a new server instead of fixing the problem. That is
like saying you need to buy a $25,000 car because replacing a $75 tire
is risky. Or like saying that you cannot change oil in your car because
it might get damaged.
Life is full of risks, and IMO adding a hard drive is not dangerous
enough to worry about in the slightest.
