Sorry!
Well,the short answer is no. You do not mention the size of your HDD,but I suspect it is a lot bigger than on your old machine,and herin lies the rub! I presume you are talking about a free space wipe,and if it`s any consolation,it takes about 2.5hrs to do one pass on my 160gb HDD with a 3.0gb processor.
Not an awful incentive to be security concious is it,when experts suggest a minimum of 3-5 passes of random data to ensure reasonable security,but people seem to want even bigger HDDs these days.The only sure answer,as always, is to not put anything really vital on the HDD in the first place!So scribble those Swiss bank account numbers on a piece of paper,and keep on your person at all times!
