Hello,

I have a Seagate SATA drive ST380013AS on my P4P800-D.
http://www.seagate.com/cda/products/discsales/marketing/detail/0,1081,587,00.html
It is my boot drive.

When I check under a diagnostic tool (aida32, http://aida32.org/), it shows
Max. UDMA transfer mode UDMA 6 (ATA-133)
Active UDMA transfer mode UDMA 5 (ATA-100).

Is there anything I can do to get the active transfer rate to
be the same as the max?

Thanks,

Navid

I have the same thing with my 160gb Maxtor SATA drive. I got the bright
idea to run various Sandra tests confirming this, and the even brighter idea
to see if a bios update would help. The Asus site implies that an update to
Bios 1014 will help disk drive speed issues. Well, it just about ruined my
system.

If you choose to flash upgrade your bios to 1014, I suggest you keep an
eagle eye on the performance of your system, and check the performance and
error logs under administrative tools. You might have to flash back to an
earlier bios (I'm using 1012 now) and/or remove the cmos battery and short
the cmos jumpers.

If it were me, I'd just say 133/ UDMA5 beats the hell out of a dead system
and leave well enough alone!

Ken,

I flashed my bios to 1014 the day it came out and fortunately, still have
not
noticed any problems.

I once saw a post somewhere that suggested that setting up RAID with a SATA
would allow the SATA disk to offer its full potential on P4P800.
But, I have not been able to find any other references.
Any truth to that?

Regards,
Navid
 
The UMDA 6 prob is a Windows prob.

Well with XP it is. As it doesnt know
what UDMA 6 is! It's not a BIOS problem.

I did read once, that Microsoft may (when I dont
know), do an update, which will fix this so
devices that are UMDA 6 will read as UDMA 6
in Windows.

I can't speak to the Windows aspect of this problem, but I did reflash to
the 1014 bios (for excitement, I guess my stable system has become a tad
boring!). My expectation was that I'd have to take out the CMOS battery and
short the jumpers afterwards, but that hopefully the bios would take.

As it turns out, I've not had a problem after the flashing, which I did
about 25 or 26 hours ago. The bios screens, however, when it comes to my
SATA-150 drive, give UDMA-5 as the highest (manual) level I can set it at;
there is no option for UDMA 6. The level automatically set was UDMA-5,
also.

So at least as far as the Asus P4P800 Deluxe Bios, latest version, 1014, is
concerned, there is no such thing as UDMA-6. And this, of course, is way
before Windoze boots up.

Interesting. I have an A7N8X D with a Maxtor DiamondMax Plus D740X
that shows up in WinXP and AIDA32 as UDMA 6. The bios settings only
offer auto or manual with no options for PIO settings. I also have a
SATA drive that shows up in AIDA32 as UDMA 6 but in this case the
active UDMA mode is 0 and not 6.
