If you encounter frame dropping while recording digital video onto your hard 
disk drive, defragmentation may be necessary.

Deactivate your screen saver, if applicable.

From the Start menu, select Programs > Accessories > System Tools > Disk 
Defragmenter.

Run Disk Defragmenter.

Your VAIO computer includes a 4-pin i.LINK connector on the front of the 
system and a 6-pin i.LINK connector on the back of the system.

A 6-pin i.LINK connector can:

supply power from the computer to the connected device if the device is 
equipped with a 6-pin connector, and

supply 10V to 12V.

A 4-pin i.LINK connector cannot supply power to a connected device.

The following Sony i.LINK 400 Mbps cables are available and recommended for 
use with your computer: VMC-IL4415, VMC-IL4435, VMC-IL4615, VMC-
IL4635, VMC-IL6615, and VMC-IL6635. Sony computer supplies, accessories, 
and peripherals can be purchased from your dealer or by contacting Sony at http:/
/www.sony.com/accessories.

It may take more than a couple of hours to complete defragmentation, 
depending on the data capacity and utilization of your computer’s hard disk 
drive(s).
