|What is it that makes you think your HDD is Failing? Have you run the Manufacturer's Diagnostic Software?|
When you buy a New HDD you get software that allows you to install the new Drive as a Slave Drive and transfer your current set up to it before you install the NEW HDD as your Primary HDD.
No need for Restore CDs unless you think you have Virus/Trojan Problem. Or you just want to do a Clean install on the New HDD.
There is nothing to learn from someone who already agrees with you.
