Thanks for the info Bruce, I will certainly check out those various
options for the next time I need to do this. Fortunately my last
attempt using 'dd if=/dev/rwd0d of=/dev/rwd1d bs=64k' with a 3.0
NetBSD install IOS image CD worked well.

         There exists dedicated software that is designed to do a
 bit-for-bit copy under such conditions. One of my favorites, mainly
 because it'll do a lot more than just copy, is SCSI Mechanic (yes, it'll
 work on IDE drives as well). Details on such may be found here:

         I've run it under Windows 2000 without any problems. If the OS
 can see the drives, SM should be able to work with them. File system and
 format are utterly irrelevant if you don't need to actually access the
 disks through Windows.
         Just as a recent example, I've used SM to make image file copies
 of the hard drives from several Telenex serial data analyzers, built in
 the mid-90's. They use a highly-customized Unix variant for their
 operating system. SM under W2K had no trouble at all creating bit-for-bit
 image files, or backup copies to another drive.
         There are other ways besides SM. I also own a dedicated
 hardware-level drive duplicator, and there are other software packages as
 well. Some examples are:

         http://www.acronis.com/homecomputing/products/trueimage/ (though
 I will freely admit I'm not a big fan of Acronis products).
         There is a big list of free utilities at this link:
