Use dd and write /dev/zero to the entire disk

For the OP who isn't a sun user.

dd -if /dev/zero -of /dev/dsk/c0t0d0s3

-if = input file
-of = output file
/dev/dsk/ c0 controller 0
t0 target 0
d0 disk 0
s3 slice 3

Adjust the numbers as needed, use 'format' to see what disks
are recognized by the system. Normally Slice-3 is the entire disk

Right. S2 is the third 'slice'. Thanks for the correction.
