How to upgrade your hard disk
Whenever in the future you'll find your computer “C” drive is getting full then your PC will be performing slowly. So time is the time to upgrade your hard disk.
This article explains how to upgrade a 160 GByte Hitachi hard disk drive to a 1.5 Tbyte Seagate disk drive, without having to reinstall my operating system, software, or having to back-up any data. The new disk has been organized so that I can install Windows 7 on a second disk partition at a later date.
The easiest way to upgrade the old hard disk drive is to clone it. You will need a hard disk caddy, which allows you to use a hard disk as an external drive. The first step is to install the new disk in a USB or Sata hard disk caddy, which is then plugged into your PC's USB port as an external hard disk drive.
Seagate provides a version of the Acronis disk cloning utility called DiscWizard, which can clone your old hard disk onto a new Seagate hard disk drive. Seagate DiscWizard gives you the option to clone your hard disk or add a new disk drive. We are going to select the "Clone Disc" option. After select “clone disk” option Seagate DiscKeeper offers either a manual or automatic mode for cloning your old hard disk drive. Seagate DiscWizard recreates disk partitions from your old hard disk onto the new drive, now the software will need to reboot your PC.
Now DiscWizard reboots the PC and copies all data from the old 160 GByte hard disk onto the new Seagate 1.5 Tbyte disk drive. Once the process completed, you needed to reboot your PC. The operating system installed a device driver for the new hard disk.
