The concept is if you have two HDDs installed, say as /dev/hda and /dev/hdb, then you can open /dev/hda and copy what you find in that 'file' over to /dev/hdb. This makes a perfect duplicate because what is 'in' /dev/hda is every sector on that hard drive. You can practise dd with a floppy or usb memory stick, for example dd if=/dev/fd0 of=/tmp/test-image bs=512 count=2880 should copy your whole floppy to /tmp/test-image. dd if=/tmp/test-image of=/dev/fd0 bs=512 count=2880 will put the image on a new floppy. I imaged a cdrom a while back, and I did not give a blocksize or block count, since I did not know how to compute it (the cdrom was half full). What happened was it copied it to a file fine and gave an IO error at the very end, when it couldn't get any more sectors. The output file was complete. This was like dd if=/dev/cdrom of=/tmp/myimage So I think you will be able to get away with dd if=/dev/hda of=/dev/hdb to transfer the contents of /dev/hda to /dev/hdb - -Andy - -- Automatic actions for USB cameras, cardreaders, memory sticks, MP3 players http://warmcat.com/usbautocam -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFAfv4wjKeDCxMJCTIRAtCqAJ0e3gD7iwsPaQEtjRfAeh+1W+gPNgCfaakb NgmW0uuIi/xUWAv9MHevGY8= =bhk9 -----END PGP SIGNATURE-----
