USB drive duplicating is usually a lot slower than with drives attached to an IDE or SATA channel.why did you create a bootable cd to perform this? could I not install both harddrives as USB (via an external case or adapter) and then clone while in Windows? or does it have to be performed in DOS?
Booting from a CD means you get 100% of the system's power. Plus, some -such as the older version of Norton Ghost I use - do run from a version of DOS.
