I have seen some cool formulas based on disk geometry but I never seem to remember them when I need them.:-( You might try something like dd if=/dev/ad0 of=/dev/ad1 bs=8192 Hopefully someone will give you a better number. ed Quoting kjerste soderberg <kjerstes@yahoo.com>: | sanity check, pls tell me if this is right | | In short; booting off of ad0 and want to clone ad1 | ad1 is blank and is IDENTICAL (SAME SIZE & GEOMETRY & | MFR ) drive as ad0 | | can I be root and do? | | dd if=/dev/ad0 of=/dev/ad1 | | running FBSD 4.3-REL | | tried it and it seeems to just sit there forever, dd | never comes back, the red LED drive light lights up | and stays lit BUT no activity on it, I mean it doesn't | hang or anything & I can ctrl-C out of it but it | doesn't work??
