If both disks are same (or nearly simmilar) size you can easily clone them using RAWDISK: device under MorphOS 2.2+
To clone whole disk attached as ide.device unit 1 to ide.device unit 2 you whould need to type something like this:
cp RAWDISK:devices/ide.device/1/rawdisk RAWDISK:devices/ide.device/2/rawdisk
(note that the cp command from MOS SDK is used instead of copy command, which sadly won't work with rawdisk)
You can also clone selected partitions (note that you would need to create them first on the target disk). Note that not all filesystems will work on cloned partitions (SFS won't - it would need to be 'repaired' with SFSDoctor to work again on cloned drive, as some partition offsets will change).
Simmilar things you can do under Linux by playing with /dev/hdaX device files.
WARNING - playing with RAWDISK and/or /dev/hd* devices is dangerous and it is extremly easy to kill you data by accident (wrong partition numer or so), so please think twice before enterring all these commands.
