Hi John, I used True Crypt last year for an External Disk and it seemed to work well. I read in the docs that it does not / cannot slow the machine down even by less than 1%. They actually said it as a 0% performance hit. Do you know how / why that is ? thanks Mark On 1 October 2011 21:13, jwcolby <jwcolby at colbyconsulting.com> wrote: > The last iteration with my laptop I used Windows Bit locker to perform a > whole disk encryption.
