SATA Stuck At Ultra DMA 5

[Greg]

I have two SATA hard drives and they both show up in Windows XP Pro (SP1) as
Ultra DMA 5, even though they are set in the BIOS for Ultra DMA 6. The
motherboard I have is Asus P4G800-V (Intel 865 Chipset). Any one know what
the problem is?

Have you checked for new SATA drivers? How about the latest Intel INF
Installation Utility?

 

[Greg]

I've downloaded the latest INF from Intel as well as tried the latest from
Asus (was probably the same though) but it didn't make any difference. Not
sure about SATA drivers... I never saw any on the Asus Web site or Intels.
I didn't need to provide SATA drivers when I installed Windows XP, but I had
read that other people did need to.

When you look in the XP device manager, are you looking under IDE ATA/ATAPI
Controllers? If so, that may be the wrong place, or maybe you are looking
at some other evice.

I have a ZIP and a DVD reader, which do show PIO and DMA mode 2,
respectively. But my two Seagate SATA/150 disks do NOT show under any IDE
controller. Further, if I examine the disks themselves, they each are
listed as Promise 1+0 Stripe/RAID0 SCSI Disk Device, since I am using a
Promise SATA controller and have the disks in separate RAID arrays.

I am looking under IDE ATA/ATAPI. Why would that be the wrong place?

 

[Greg]

Also when I boot both SATA drives show up on the screen as only Ultra DMA
Mode 5 (I set it in the BIOS from auto to Mode 6 but didn't make a
difference).

what you set in the bios doesn't effect XP. UDMA 5 is correct for SATA on
an 865/875 motherboard. no worries...
