Sata and gdisk

[pgwood]

Gday
Has anyone tried to gdisk a Sata drive from a dos boot floppy ? Mine just freezes as though it can't see the drive , but fdisk doesn't have a problem seeing the drives....? Maybe I need to use something other than gdisk.
I need to delete partitions and create on the fly from DOS only. (Blow it away , create a sized partition etc and clone)
Any help or clues appreciated...

Forgot to mention -- Tried it from a floppy and it works, try it over a dos network connection and gdisk dies.......
yet it works on all other disks we deal with..wtf.
Basically , I want to blow away (delete partitions)on a 120Gb SATA disk, create a primary (50%), and extended. But I need to do this in a batch file (thus a dos command line utility). The reason for this is to engineer out human error.

Fixed --- gdisk /I and ghost -fni
