    I'm installating WHS 2011 on hardware that previously ran WHS 1.0.  All data has been migrated to another storage medium so I can perform a clean install.

    I first installed WHS on a 400GB drive with other drive trays disengaged.  I then shut down, engaged 4 drive trays with 1TB drives. WHS 1.0 had been installed on one of those 1TB drives, so I configured the BIOS to boot from the new "0" drive (400GB).  Upon viewing the attached drives, I see that one 1TB drive has a 20GB partiion on it from the old WHS 1.0 installation.  I am trying to wipe that drive clean and remove the old partitions, but the disk management utility in WHS won't seemly touch that old partition.

    Any suggestions what I am missing?  Probably something obvious.  Thanks!

    Nothing obvious I can think of. So, you can't delete the 20GB partition with WHS2011? Under these circumstances I would disconnect all drives other than the problem one and boot from one of the Linux distribution disks and do it from there - faiing that try a Windows installation disk in the same way.

    Disk Management won't touch that partition because it's recognized as a system or boot partition. You should be able to get rid of everything on that disk using the diskpart command line tool, however. I will note that doing so is unsupported, as is everything done through the server desktop rather than the dashboard. And you do this at your own risk; the diskpart command has no safety net or undo, so if you clean the wrong disk you're screwed.

    To do so:

    • Start an elevated command prompt.
    • Type diskpart and press Enter.
    • Type list disk and press Enter.
    • Type sel disk # (replacing # with the appropriate disk number) and press Enter.
    • Type list part and press Enter. You should see two partitions: one 20 GB, one (disk - 20) GB.
    • Type clean and press Enter.

    You can learn more about the diskpart utility here.

    I'm not on the WHS team, I just post a lot. :)

    Makes perfect sense.  Since I have no data at risk and the worst case would be a fresh reinstall of WHS, there's not need for a safety net in my case.  Thanks!  John
