How do I install n Advanced Format Drive on my pc?

First of all, if yours is a reasonably new motherboard you don't have to worry about jumpers. But your 'old' Dell needs to have SATA ports. If not you have bought the wrong one & need to exchange it for an IDE drive.Partitions are areas you can divide the hard disc up into during Windows installation if you so wish. Not compulsory. Software you will need are the Motherboard drivers. You might have to try & download that from Dell. If your Dell has a dedicated video card you will need the drivers for that as well. You will need to get all of those drivers before you start. And you will need a genuine copy of Windows XP. If you have everything you need start your installation with the Windows OS disc. You will be prompted at the correct time to use the others.
