Why do you want to use DOS? You can delete/create/format partitions using the XP disk. Do you have a floppy drive? Boot off a WinME boot floppy, run FDISK from the A:> prompt, delete all partitions, then recreate new partitions. However, you will have to format using FAT32.

Another option would be to use the software available from the HDD manufacturer, or use a 3rd party partitioning/formatting tool. UBCD should have what you need:
The short answer is that you can't. DOS has too many limitations.
You would have to install DOS to do that, which is pointless. Windows has no DOS, only Command Prompt which is running within Windows. You can't format when Windows is running so that is no use.
Use the advice already given.
Always pop back and let us know the outcome - thanks
