On many Unix systems it is not necessary to use dd at all - you can
just copy the data to the disk using "cp".
For example, to copy a plain disk image to disk on a sun4, (where
/dev/rfd0c is the raw block device associated with the 3.5" drive,)
you can use
cp <image> /dev/rfd0c
or even
cat <image> > /dev/rfd0c
and if you have a compressed disk image, you can just use
zcat <image.Z> > /dev/rfd0c
If you have to use 'dd', then it is probably best to select a 9K block
size for 3.5" disks: use
dd bs=9k if=<image> of=/dev/rfd0c
or
dd bs=9k < <image> > /dev/rfd0c
Try using cp or cat first - it's probably the easiest way.
