Best method is a drive duplicator. I had to use a drive duplicator to duplicate scsi drives before for operating systems that were unable to have clone software added to.
Its costly, but my employer fetched the bill for this at my last job and it works perfect. It comes with adapters for pin conversions too and cables. BUT its expensive at $495
http://www.digital-loggers.com/sdiprop.htmlThere are cheaper methods to doing this but more involved and not as guaranteed to work as flawlessly as the duplicator. A linux based system could DD one drive to the other, and on newegg you can get 50 to 68 pin converters etc.
