It is not *usually* a good idea - more often you need to enable it.
But Control Panel - System - Hardware - Device Manager and in IDE
ATA/ATAPI Device Controllers, look for either Primary Channel or
Secondary, depending on where your drive is connected; double click, and
in the Advanced page - Transfer pane for the device, select PIO only.
Do *not* put Primary - Device 0 into PIO; that is the main Hard drive
and doing so will slow it down.
More to the point, have your hard disk well defragmented so that the
heads do not waste time dancing around to find bits of files.
