Windows 7: diskpart script hangs at "select disk"

Hi. most of the machines I deploy have two disks. I am using a diskpart script to clean and format the disks/partitions. Well, I need to be able to deploy onto a machine that only has one disk. Since the "select" command doesn't have the "noerr" option the script fails on the single disk machine. Is there a way I can modify the script so that it will work on both configurations? Here is my simple script:

select volume 0
remove noerr
select disk 1
clean
select disk 0
clean
select disk 1
create partition primary
select partition 1
format FS=NTFS label=Voyager-1.0 quick
active
assign letter=c
select disk 0
create partition primary
select partition 1
format fs=ntfs label=DATA quick
assign letter=d
exit

Thanks in advance,
Rob

Am I right to assume that you are trying to partition a single disk into 2 partitions? And for this single hd machine, are you running diskpart from a bootable media?

Thanks for the quick reply. To answer your question...
The script I posted basically partitions two disks with one partition each. The first disk is the system drive (c) and the second disk is a data drive.

On the laptop there will only be one disk and it needs to be a single partiton (c).

The problem is when my script tries to select the second disk and there isn't one on the laptop the script will hang. If I could use "noerr" on the select command I think it would be fine. I am PXE booting into winpe and the script is being called from the bootstrap.ini file. I think there needs to be some logic in the script that detects the number of disks first, but unfortunately I'm not a very good scripter and am not sure how to approach it. I was hoping there was a simple way to add the logic into the batch file posted rather than try and write a .vbs script. I'm decent with powershell but winpe doesn't have it and adding it is an extra step in addition to writing the actual script. I hope this makes sense. Thanks again.
