I think it's called "dd". Google search for "tom's root boot" which is a startup disk that has it.

Yup, dd (disk dump) is the command. Read the man pages (man dd) for syntax/usage.

Benthemeek,

After re-reading your post, I don't think that dd is going to do the job for you. As far as I know, dd can't deal with the source and target location being the same, as diskcopy could.

Can you make a boot disk from the install CD? RedHat Linux can, using the program rawrite to transfer the file boot.img to a floppy.

dd can be used if you use the command twice.
First make a image file on harddisk and then copy the image file to a new disk.

dd if=/dev/fd0 bs=1440k of=/disk.img

This command will copy the floppy to a file
named disk.img in the root partition.

dd if=/disk.img of=/dev/fd0 bs=1440k

This will transfer the image to a disk in fd0
- unless you use supermount in which case you
will get an error . Need root privileges to
do it all .
