Worked great for me, too!

I had a 10GB disk that dual boots Win98 and Red Hat Linux 8.0 using grub.
- I attached the new 20GB hard drive as the slave on the secondary IDE bu=
s,=20
temporarily taking the place of my ZIP drive.
- I booted from the CD with my Red Hat System Administrator's Survival CD=
=2E=20
(I'm sure any CD bootable Linux would have been fine.)
- I issued the command "dd if=3D/dev/hda of=3D/dev/hdd" You'll note I fo=
rgot the=20
"bs=3D512" and that worried me but I figured I would just let it run anyw=
ay.
- When it completed in about 40 minutes (I think? Maybe less. Should ha=
ve=20
timed it.), I reconnected the ZIP drive and connected the new 20GB drive =
in=20
place of the original boot drive.
- It boots like nothing happened! All is normal.

Now I need to learn how to use the parted utility to partition all that b=
lank=20
space!
