Hi,
Some brave soul was successful in installing and running a 200GB Western Digital.
He only got access to 137GB of 200 because of the UTV limitation.
That equals a max of 110hrs compared to the 120GB 105hrs...
Kind of expensive but possible as long as the drive supports Security.

Other users have tried other drives like the 160 and 180GB in the past...
Those too should work (at 137GB) as long as they support security.
A 200GB might be better suited for your PC and your UTV happier with a 120GB...
Later,
David T.
