I have bought a removable hard drive enclosure and a 1TB hard drive to fit in it. Its pretty cool; it has a little handle at the front of the caddy that allows you to take out the hard drive and stick into another caddy - or swap it for another hard drive, whatever you choose.
The manual talks about converting your dynamic disk to a basic disk if you want the ability to be able to use the "Swap Manager" software (some 3rd party software to allow swapping out of hard drives).
Can anyone explain to what the pros and cons are of having a basic vs dynamic HD?
