Widnows XP / Server 2003 does not allow upgrading from basic to dynamic disks on a laptop, reason being in laptops there is usually one hdd and if there are two, one of them is removable and usually far from the pc enough time to make dynamic disks useless.

I have two hdd on a laptop of mine, I put a screw to lock the removable bay of the second one, and I want dynamic disks and raid 1. The option to configure dynamic disks is grayed, and I can't find any ref, official or non official, to what reg key should be modified to make the OS believe it is ok to upgrade to dynamic, or even it is not running on a laptop.

Does anyone happen to know anything about it? Does anyone know how does Windows Server know it is installed on a laptop pc, in the first place? There must be a reg key, but as usual it is going to be a major search effort to find out.

Thank you in advance
