inefficiently in small chunks rather than as a single

menu of most Windows installations.
• Check hard drive data rates: The Pinnacle video-
editing software has a built-in test that measures the
speed at which the capture drive transfers data. If the
drive is not running at optimum performance levels,
some video-editing operations may fail.
To run the hard drive data transfer rate test:

of the setup box, click the Test Data Rate button.
The hard drive test will run. On most systems, data
rates will be between 25,000 and 35,000 Kbytes/sec.
Note: If you make changes to the system that increase
the speed of the capture hard drive – such as enabling
DMA – you will need to run the hard drive data rate
test again so that the software will recognize the

Use Pinnacle’s PCI Performance Enhancer utility,
