Thanks for the many responses....

Original Query:

I am tasked with ensuring no data is left on a large number of disks on 
servers we are returning on lease expiration. I have done some preliminary 
searching for techniques or tools for this task without success. 
What say my brothers/sisters at arms on this subject? 


dd if=/dev/random of=/dev/rdsk/<spanning partition of whtever disk)
or if-/dev/null

format - analyze - write/compare/purge/verify

Some suggested newfs but as documented in this sunmanagers archive article
newfs does very little to remove data (should have checked here first - Tim
