The chinese stuff has been liberated from other sources so support will be spotty. You should be able to buy a HD with the operating system on it. That op system will be locked to the SN of the HD.

Best way to run this is to get a 2nd HD carrier and swap out as this will keep your regular lap top OS clean.

And what ever you do, never let that computer hook to the internet when it is using the DAS HD ( even through a wi fi that auto connects ) it will phone home and be bricked remotely.
