How to clone the contents of one hard drive onto another

Can anyone recommend a different CD bootable utility I might try to clone a hard disk drive?

I've so far failed to perform the seemingly simple task of cloning the contents from a small hard disk drive onto a larger one.

Apparently Hitachi (target) doesn't offer a bootable utility for this. But, that's okay because Western Digital (source) does!

Western Digital Data Lifeguard Tools 11.2 for DOS (CD)

But, when I boot from its CD, it immediately reports that it now doesn't have a SATA CD driver?!?

blah blah blah

Well, there is a floppy version:

Western Digital Data Lifeguard Tools 11.2 for DOS (Floppy)

So, I pried a floppy diskette drive from an old computer, hooked it up, created the boot disk, rebooted the PC, and it failed too!

Starting Caldera DR-DOS...
Can't load BDOS kernel file: A:\IBMDOS.COM
System halted.

I reformatted to try again, but then I then couldn't create the disk.

The tab was closed. I toggled it and retried several times. I even tried different diskettes. Same error each time. I guess my ancient floppy diskette drive must be broken.

Update: I've salvaged a second floppy disk drive from an old computer. It also insists that the diskette's write-protect tab is open. Windows will format it, so it's Western Digital's issue.

Update: Perhaps it's a problem with Windows Vista. I was able to create the floppy diskette with Windows XP.
