Plextor PX-760 - Set the PX-760 SA DMA Jumper (if Needed)

Section 3. Installing the PX-760SA Internal SATA Drive
PX-760 Installation and Users Manual 41
If your drive came pre-installed, some or all of the items above may
have been installed and may not be separately available. See the Plextor
web site for locations to purchase additional or replacement accessories.
Set the PX-760SA DMA Jumper (If Needed)
Your PX-760SA ships from the factory with no DMA jumper installed.
(The pins are empty.) The empty pins mean the drive is set to Ultra
DMA. This setting should work in most cases, so you don’t have to do
anything more.
With some personal computers that do not have an embedded non-RAID
Serial ATA chipset, the computer may “hang” or crash with the PX-
760SA installed. If this happens, change the PX-760SA to multiword
DMA mode by installing the spare jumper across the two DMA jumper
pins.

from Ultra DMA (default) to multiword DMA
Adding the jumper also configures the PX-760SA for self-test. See
“
Using the PX-760SA Self-Test Diagnostics” on page 68 for more
details.
