Finally I think I found where the problem is.

Vista thinks disk 0 is a removable drive so I cannot extend any partition on
disk 0 by joining it to unallocated space on disk 1.

Now, if I'm right, the question is WHY it thinks so and HOW can I revert
this ?

motherboard: asus p5rd1-vm
controller: integrated ULI M1573 southbridge, 4xsata with raid 0, 1,
0+1, jobd

ULI's manual doesn't report hotswap capabilities and I did not use raid (I
have only one sata disk, disk 0).

mmmmmmmmm .....
