Thanks for the reply. (I'm a colleague of Toby's). Yes we are using the sstk but also other utilities. We've managed to get this working by using diskpart to create the drive, then format it and then using gdisk32 (partition utility comes with ghost) to reinitialise the master boot record (gdisk32 1 /mbr). We then run an unattended windows installation and the server reboots to continue the installation correctly rather than hanging at "booting to C drive". Just going to see if I can some how get rid of the need to reboot between creating the array with cpqacu.exe and doing the disk partitioning part. Thanks Neil
