I recently purchased a Dell 5150C with a Samsung HD160JJ/P hard drive. When running the diagnostic program Sandrasoft a message comes up saying that the optimum speed is not being used. It shows UDMA 5 instead of UDMA7. The drive is supposed to be SATA and I beleive therefore should be using UDMA7. I have checked BIOS and everthing appears to be enabled correctly. Checked Samsung site and downloaded manual for drive. It mentions a limiting speed jumper for 1.5GB/S on 3GB/S products in rare occasions. Is this applicable to Dell computers interface? Any help would be appreciated!
on the hard drive itself there is sometimes a jumper to limit the speed to 1.5Gb/s. But as far as I know it still remains a SATA drive no matter what jumpers you have in place.
