Since few days am experimenting with few tools to clone my existing Mac disk to another of my USB backup drive (WD 250GB Passport) so that I can re-partition the existing primary disk to have a room for Bootcamp. This is needed because the OS am running is the image from Yahoo! which has lot of tools thats hard to reinstall back. So having a complete image makes the life much easier.
I found two nice tools which can actually clone the disk and moreover they are free.
I could not able to install SuperDuper! for some reason as the downloaded .dmg file is not mountable on 10.4.10, contacted the product support team, and a got a message that the downloaded file is corrupt. I did tried this with all other 3 browsers and from 4 different locations, nothing seemed to be working for me.
On the other hand I was able to install Carbon Copy Cloner without any problems and did a complete clone of the existing disk to USB disk using couple of clicks and it just took few hours to complete (~50GB). To test the backup disk how it really works, I rebooted the Macbook with this USB drive and the system seemed to be up and running from USB disk and behaves exactly as the primary hard drive except that it took little longer to boot.
Now, its time for me to play with the primary hard disk.
