Boot Disk copy with dd command

I have my Primary master 60 Gig as a boot disk which has W98, W2000 and RedHat 8.0 installed on it.

On Primary slave, I have a 120 Gig hard drive and I would like to use 'dd' command to copy the 'entire' boot disk to this disk as a back up if the other disk failed.

Is it do-able ? Can I boot with my back-up assuming I switch (trading places) the disks. Both disks are jumpered to Cable-Select ?

i think it should be possible. anyway, i suggest using another tool like parted or something like that to simply copy the partition from one to the other disk.

make a partition with the ~same size on the 120G drive and ´cp /dev/source #minor #minor(dest)´ with parted.

sl mritch.
