Hi!

First of all, sorry for my english! Then ...

I'm not able to expand a disk partition joining it to a new disk under Vista HOME PREMIUM.

environment:

disk 0 : sata, ~400 gb, volume C, volume D

disk 1 : pata, ~300 gb EMPTY

disk 2 : pata, ~120 gb, volume E

- disk 0, 1, 2 are all basic disks
- C is a primary, boot/system partition and holds pagefile, hibernate, etc.etc.
- both D and E are primary partition
- C, D, E are ntfs created by vista


My problem is that :

I'm able to extend volume E using empty space on disk 1 BUT

I'm NOT able to extend volume D using empty space on disk 1 (the option "extend" is grayed out)


So it seems to be possible to join a partition to unallocated space belonging to another physical disk.

I wonder why I can join E: to disk 1 but I can't join D: to disk 1.


Many thanks to everybody.

Luca.

I presume that disk C: is your boot volume - as such you cannot extend it. Here's a link that describes this: http://technet2.microsoft.com/WindowsServe...3.mspx?mfr=true

Yes, C is my boot and system volume.
But I don't want to extend C.

I want to extend D !!!



technet says:

- You can extend a volume only if it does not have a file system or if it is formatted using the NTFS file system.


and D is ntfs

- You can extend simple or extended volumes that are not system or boot volumes

D is simple, is not system, is not boot

- You cannot extend a system volume, boot volume, striped volume, mirrored volume, or RAID-5 volume.

perhaps this is the point!

D belongs to disk 0 which is SATA attached to ULI raid controller.

BUT I obviously didn't create a raid-5!!! disk 0 is the only disk attached to this controller.

Sorry! I misread the post.

I'd try shrinking it the partition on Disk 1 and then try to extend D: to the unallocated space (inferred from this link: http://technet2.microsoft.com/WindowsServe...3.mspx?mfr=true )

Other than that, I'm at a loss. The only other thing that I can think of is that the "extending" pertains only to the disk itself and not the partitions (as if were only capable of reading from the MBR). If that's the case, then it'd be treating the D: as a part of the boot volume and wouldn't allow it (but this is just speculation on my part).

I tried but it didn't work (not enougth free space to shrink).

But 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).

Thought the same at first.
But seems very strange that all technet articles state about VOLUMEs' requisites regarding boot/system, not about disks's.



Never mind.
Thanks to have taken time to answer me.
