Solaris disk wiping utility?
 
I'm used to using CBL Data Shredder on XP. Wondering if there's something comparable for Solaris.

dd can do the job.

something like:

dd of=/dev/rdsk/c0t4d0s0 if=/dev/zero

that will overwite every single block

obviously this isn't the same as strong magnets or a good sledgehammer.

a lump hammer was very enjoyable once :-)

My friend with the downstairs apartment under a faulty hot tub assures me that brominated water can be highly effective.

I like to be able to use the drives again, or even sell them. :) However, next time I need to completely destroy a drive I'll look for an apartment under a faulty hot tub! :) :)

trust me the hammer is the most fun.

dd wont cause any damage.

If you want a similar technique that the one used by data shredder, you can try that:

Code:
for i in 1 2 3 4 5 # increase for more security
do
  echo pass $i
  dd if=/dev/urandom of=/dev/rdsk/<your partition or slice here> bs=1024
done
and be patient ...

Well, when we actually want to completely destroy a drive (for example, a failed drive), we have a decent sized press out in our maintenance department that does a good job... :)

I like jlliagre's script, I think that'll suit my needs in this particular case.

Thanks all!

Well, you could put it on a string around your neck and get in if you prefer, it's more scalable.
