The company I work for is selling part of it's IS infrastructure to the highest commercial bidder. This could well turn out to be a competitor and so to 'tick' the risk-assessments etc. I have to come up with a way of formatting the server HDs beyond all economical data recovery.
Are there any tools that would do this? Preferrably free-ware, but would consider paying for a tool if it's the only option.
Or, is replacing all server HDs the only way to truly 'tick' the box?
