RPM on RAID Drives
- Hello all,
Four 500GB drives in RAID 5 array. Presently set-up as one big C: drive.
Windows XP x64
Goal: separate partitions for Windows XP, Windows XP x64 and data.
I cannot get RPM to run on this machine. Is there a version that will
run under my OS? Will it work with my disk set-up? I have also tried
Acronis and Norton partition managers with no luck.

failed, so I would have to guess. Please correct me where I am wrong.
You have some unnamed RAID board with 4 drives attached, to a net total
of 1.35 TiB, and no other disk in sight.
Since you are under the 2 TiB barrier (and using an OS which AFAIK
cannot boot from anything else than MBR partition scheme), you
partionned it using Windows with MBR scheme.
You do not have activated BIOS support for the RAID board, so you used
the "scsi" 32-bit driver for your board, renammed to NTBOOTDD.SYS, in
order to boot the system, and you are using the scsi() syntax within the
> Is there a version that will run under my OS?No. RPM runs under a (private) 32-bit extender on top of BIOS or DOS,
excluding any other alternative.
Note it is not usually a problem, since you are not expected to surf the
web or building a spreasheet at the same time you are changing the
partitions of your hard disk. :-)
> Will it work with my disk set-up?If you are in the very setups I described above, no (unless of course
you have knowingly disabled the BIOS support, in which case it is as
easy as re-enabling it): RPM needs BIOS support to access the disk.
In a similar case, I had success with Microsoft's diskpart running on
top of Windows PE (or BartPE, or whatever similar tool) with the very
same specific drivers you use to access the array. Very rough, but it is
able to do most tasks you may perform with RPM, just that you do not
have the level of control RPM is giving you.
> I have also tried Acronis and Norton partition managers with no luck.It is not the place to discuss these tools here (and I am not fluent
with them either), but I would have expected success with them.
Furthermore, since they are commercial tools with respectable companies
behind them, I am surprised their support gave up.

What you are really asking for is to be able to resize (shrink) your
existing C: volume, in order to create two new volumes (for another
Windows and "datas"), ain't you?
And of course the present big volume is formatted as NTFS...
So what you are asking for is a tool to shrink a NTFS volume.
Of course RPM is completely unable to deal with such a task, first
because it does not known anything about NTFS, and second because it is
not the right tool to use to shrink a volume.
Of course there are ample material covering this on the web, but it
should suffice to say that this is a task that can be done with the
diskpart version included with Windows PE 2.x (freely available from
Microsoft if I understand correctly the licensing conditions, seek about
Hope it helps,
