I have a pair of IDE hard drives and I want to do a
raw copy from one
to the other. I've tried a couple of different approaches so far
without much luck.
My first experiment was with linux where I created a
PC linux boot CD
and hooked my two drives up planning to just dd from one drive's raw
device to the other. [...trouble...]
Can't help here; I don't know Linux.
My second attempt was with a NetBSD 3.0 install CD,
exiting to the
shell and trying dd from rwd0a to rwd1a. I know that back in the
dark ages, this was possible, but apparently in these modern times
things have changed. When I try to do this I receive a read only
error on the /dev/rwd1a device.
This is because the partition table you have on wd1 makes wd1a contain
the disk label; it's refusing to let you casually overwrite the label.
You can avoid this by using wd0d and wd1d, assuming you want to copy
the whole disk, or by using disklabel -W to enable overwriting the
label on wd1.
