There was a thread on this about a year ago. I think Civileme and Sridhar were discussing it. A search in the archives might be useful. Also most HOWTOs you find might make it look more complicated than it is. I do believe diskdrake will do the whole thing for you nowdays. If it works out OK for you, I might take my own advice and put that old hard drive to use :-) derek
