What's the easiest way to wipe HDD label & Partition info off drive?

Question  What's the easiest way to wipe HDD label & Partition info off drive?
Hi,
  I'm experimenting with Irix OS installs...blanking the doot drive (ID1) enough to call it "empty" to try another install is seemly difficult.   I was hoping I could use what I do under linux and just DD the first 10MB or so of the drive to wipe all partitions and volume info so I could just re-FX everything. I'm afraid if I just mkfs on the root parittion that I'll still have old volhdr sash files stuff and such.  I'd rather the installer see the drive as blank...just easier.

Suggestions on how to do this without removing the drives. Can I just boot sash from CD and somehow run DD against partition 10?

OR can I reference the entire disk some other way from PROM miniroot to "blank" the used drive without low-level formatting it (I don't want this after I've already done it once on a disk during drive check-up).

Thanks!
