I have three HDs in my computer ASUS P4C800-E Deluxe.
All Seagate 120GB HD0 + HD1 8MB cache and HD2 have 2MB cache.
Two (HD0 + HD1 8MB cache) connected to first IDE-port (Intel)
with cable select. The third (HD2 2MB cache) connected to the
Promise controller also with cable select.
The "problem" is that the two disks connected to the Intel
controller only use Ultra DMA-2 and the third connected
to the Promise controller use Ultra DMA-5 !
That is what DTemp report from S.M.A.R.T.
Se details here

How to change to Ultra DMA-5 for my first two drives?
I use Windows 2000 professional.

Can you change their DMA in the Device Manager?

If the asus mb is only mode 4 capable and you use mode 5 drives then it may
be defaulting to the lower mode 2

in this case you need the hard drive utility from seagate to let you report
the mode 5 drives as mode 4 to the bios!

if it IS the case that your mb IS mode 5 capapble then the utility still
might solve the problem
 
Just thought of something else

You ARE using 80 wire ide cables arent you?

40 wire cables will only allow you to run at ata33 (mode 2)

Yes. I even tried the working cable from my disk
that are in UDMA 5 mode now.
I'm going to interhange the disks and try every combibnations.

Now it's done. All 3 disk and both cables can do UDMA 5.
The problem is in the software or the primary IDE port.
I don't know where to search.
 
WD DLG which is WD's diagnostic. You might have to change
the firmware to the UDMA that matches your ports. Use the
bootable floppy from WD.

It's an installation for drives and does not seems work only
for change from UDMA 2 to UDMA 5 on an existing working drive.

Isnt that what you want to do? Change your mode 2 drives to mode 5?

I thought your 2 drives were working and it was just the fact that they were
in mode 2 and you wanted them in mode 5?
 
To compare with others you can go to my site under comp/bench & there
you have also Sandra2001pro (stripped) DL to bench your HD setup to
get that index (you can see my bench of my old drive there too). Than
TELL me here the result in points you have got; I am very interested
in this result ; please do it for me .. :-) Thanks! (do that w/o any
background applications running if possible)...

Buffered read and write are a lot faster on the Promise controller!
The 8 MB cache make the drive a little faster.

If all 3 HDs are same capacity & RPMs what are index bench results;
just curious to see real life differences between UDMA modes
on those 3 HDs ...

Yes all 3 drives are this:
HD1 Seagate Barracuda V 7200rpm, 120GB, 8MB cache.
HD2 Seagate Barracuda V 7200rpm, 120GB, 8MB cache.
HD3 Seagate Barracuda V 7200rpm, 120GB, 2MB cache.


-------------------------------
The first results is like this:

IDE master IDE slave IDE (one drive present)
Intel ICH5R Intel ICH5R Promise 378
HD1 8MB HD2 8MB HD3 2MB

30 MB/s 30 MB/s 1200 MB/s Buffered read
27 MB/s 29 MB/s 36 MB/s Sequential read
5 MB/s 7 MB/s 6 MB/s Random read
30 MB/s 30 MB/s 1240 MB/s Buffered write
29 MB/s 29 MB/s 35 MB/s Sequential write
8 MB/s 7 MB/s 8 MB/s Random write
9 ms 8 ms 9 ms Average access time


-------------------------------
When swap HD2 and HD3:

IDE master IDE slave IDE (one drive present)
Intel ICH5R Intel ICH5R Promise 378
HD1 8MB HD3 2MB HD2 8MB

30 MB/s 30 MB/s 1550 MB/s Buffered read
27 MB/s 28 MB/s 38 MB/s Sequential read
5 MB/s 6 MB/s 7 MB/s Random read
30 MB/s 30 MB/s 1740 MB/s Buffered write
29 MB/s 29 MB/s 37 MB/s Sequential write
8 MB/s 7 MB/s 8 MB/s Random write
9 ms 9 ms 8 ms Average access time


I made 2 test runs on every combination.
There was minor differences.

Yes, but that program from Seagate can't do that.
 
When I make changes in BIOS to "comatibility mode"
the Intel ICH5R change to Ultra DMA 5 for Primary IDE !
(but then the secondary IDE don't work and my CD unit is unusable)
I think all this this is att BIOS problem.


New tests:

All 3 drives are this:
HD1 Seagate Barracuda V 7200rpm, 120GB, 8MB cache.
HD2 Seagate Barracuda V 7200rpm, 120GB, 8MB cache.
HD3 Seagate Barracuda V 7200rpm, 120GB, 2MB cache.


-------------------------------
The results is like this with UDMA5 on all ports.

Primary Primary Extra IDE port
IDE master IDE slave IDE (one drive present)
Intel ICH5R Intel ICH5R Promise 378
HD1 8MB HD2 8MB HD3 2MB

84 MB/s 82 MB/s 1633 MB/s Buffered read

My computer:
ASUS P4C800-E Deluxe
Intel Pentium 4 Northwood 3.2 GHz
1024 MB ECC memory (2x512)
The Promise controller are on the motherboard.
BIOS version 1016
 
are you 100% sure that the ide cable is connected with the blue end in the
m/board?
few have found that if it's the wrong way then the attached drives run in
udma2.
cheers

If I change to "compatibility mode" in BIOS it work with UDMA5
for my both drives on the primary IDE channel, but then my
CD player on secondary IDE channel disappear.
I think this is a problem in BIOS.
I'm going to flash a newer BIOS version some day.
 
Ken If you are using the ide controller from Intel, try to remove it and
install the standard ide controller provided from M$. See if that has any
effect.

Thanks. I would try every tips (but it would take time).
 
If u have more than 1 device per ide channel u cant have dma 5.
Its as simple as that.

I don't think that's right.
Yes I have 2 identical devices on the same IDE cable.
With only 1 device I also only get UDMA2.
If I configure BIOS for "compatibility mode" i got UDMA5
with both devices connected, how do you explain that?
UDMA5 with 2 hard disk on the same cable works!

Ide is restricted in many ways, but its cheap.
I can only guess that another controller might help you best here.
Anything else is just a waste of time.

No I don't think so. I have some BIOS problem or driver problem
with my old Windows 2000.
