Hard disk drive recovery
When you replace the original hard disk drive, the preinstalled VAIO Recovery Wizard utility program cannot restore the drive partitions, operating system, or original software programs. Before replacing the hard disk drive, create a VAIO Recovery Media Kit or purchase a kit from Sony.
Your VAIO® computer is not supplied with System or Application Recovery CDs. Use the VAIO Recovery Wizard utility to recover your computer's operating system and preinstalled software programs.
For more information about the VAIO Recovery Wizard utility program:
Click Start from the Windows® taskbar, and then click Help and Support.
From the VAIO Help and Support Center, click VAIO Recovery Options.
Hope that helps,
