I don't know if it is already notified, but I've got an 2,5" HD 500gb hard disk in a 2,5" case. I did two (primary) partitions one of 16GB and another partition with the rest of the space for data (so in computer management --> disk management the disk is recognized as a basic disk). I used a nlite source and created, with the winsetupfromusb, an installation in the first partition of the disk, booted from the usb and all the installation went fine, first boot, second boot... all fine. Then it happens that this installation of windows xp recognizes this disk as removable media (my latop, work computer still recognize it as a basic disk) so the second partition dissapears (only for this windows xp installation) and there is no way AFAIK to change it. In the end I reinstalled using the normal nlited CD installation (wich recognizes the HD as a basic disk).
