[Guest]

OS: WindowsXP Pro SP2 with all the updates
MB: Asus A8N-SLI Premium
Proc: AMD 64 X2 +3800
RAM: 1G, DDR400 PC3200
VGA: MSI-nVdia NX6800GS 256M, PCI Express
Primary IDE: HD WD 120G partitionned in C: [boot NTFS] Windows XP 80G , D:
[FAT32] Swap for Linux 10G, the rest is unallocated yet,waiting for Linux
(maybe)

The Problem

New HD: SATA2 WD 250G, 16MB installed in 1st SATA slot ( MB have 2 SATA
controllers with 4 SATA slots each and with 2 RAID controllers) Anyway, I
installed the HD using Disk management console > Dinamic Disk>Single Volume
on Single HD (whole disk 232GB)>Format NTFS > became F: > after 1st reboot in
My Computer I see F: and H: identical Volumes pointing for the same HD

I'm confused, please Help

Unless you have a good reason for the new HD being Dynamic, convert it
to Basic.
