Toshiba hd in Sony laptop-very low uncached speed

whoops · 10-05-2006, 08:32 AM

I have a very slow start up. I ran the tests from PCpitstop and they indicated poor disk performance. When going to the details of the poor performance, uncached speed of 2/mbs when it should be 20/mbs. They said causes might be disk driver, disk interface, or the physical disk itself. I tried their suggestions for fixing, but disk performance is still poor.

Well, by very slow startup, it could be the drive structure itself. The cache on laptops are uusually 8MB seek for fast ones, 4MB seek for medium and 2MB seek for standard ones. the speed of the IDE (IDE/66, 100 or 133) will tell the entire difference. Although, it could be due to a defrag. Try defragmenting the drive.

Definitely defragment the drive as it will help performance (make sure to do it in Safe Mode for better results).

Check the Properties of the hard drive in the Device Manager (Control Panel -> System -> Hardware tab). Enable write caching if you can and if it's not already enabled, and set the optimization to Optimized for Performance in the Policies tab.

By the way, is it running in DMA or PIO mode?

When you moved the drive over to the Sony laptop, did you reinstall Windows?
