VTOC ZFS back to UFS

I have reverted back to solaris 9 after testing out the new 06/06 version of solaris 10. A number of disks have zfs pool vtoc information, i want to clear this and have tried over writing with dd as well as fmthard to replace vtoc. but neither work!

other than running a format on the disk (which is 35mins times 9 disks!) and without reinstalling solaris 10, how to get i get slice 2 to begin at block 0 and end at the last block!

and where is clise 7? see below.

Current partition table (original):

Total disk sectors available: 71116541 + 16384 (reserved sectors)

Looks like an EFI label. (slice 8 reserved, no slice 7).Use 'format -e', and when you label the disk it should prompt for EFI or SMI label. You want the SMI label.-- Darren
