I think you should just be able to go ahead and put it in fstab. Whether 
it gets mounted or not at boot depends on the "noauto" keyword - see man 
fstab. If the drive isn't physically present, (but is "expected" in 
fstab) nothing bad will happen to the boot process, provided that you 
haven't got anything important (eg /home) mounted there.

As for hotswap, the important thing is that you can unmount the device. 
Once that's done, it should be easy - I *think* it's just a matter of 
using "eject", and unplugging it (provided both devices are SATA).
You should check this though.

P.S. Note that you can't unmount a device which is busy. So make sure no 
programs are accessing it, or have their current directory on it.

P.P.S. /media is usually reserved for "removable" media. It's a matter 
of taste, but you may prefer to use /mnt, or even something dedicated 
such as  /backup .
