Can somebody help me go from DMA mode 6 to DMA mode 5?

Hey folks! I have been searching high and low for days now on a solution to my problem… and I just don’t know what to do! Perhaps an expert can help me out?

I just got a new HD that supports UDMA mode 6 (133mb/s) and installed it into my computer. My motherboard supports UDMA mode 6 as well, but when I boot up into Windows, my motherboard’s audio is all crackly and annoying! The problem wasn’t existent when I was using my old HD – which ran at UDMA 5 – so I presume it’s the mode 6 that’s causing me problems.

Here’s what I’ve done to solve the problem, but so far nothing has yeilded a solution:

[ul][li]I’ve updated my motherboard’s BIOS to the latest available.
[/li][li]I’ve installed all the latest motherboard drivers (including chipset, sound, and IDE) from my mobo manufacteror’s website
[/li][li]I’ve uninstalled and reinstalled all possible drivers for all possible devices
[/li][li]I’ve searched for (but not found) any drivers/utilities for my HD
[/li][/ul]

The only solution I can think of is to force my HD back to UDMA mode 5, but I can’t seem to find a way to do this. I can’t find any registry entries anywhere to revise… I can’t find any setting in my mobo’s BIOS… I can’t find anything to suggest that such an option is possible!

It’s GOT to be possible though, as my friend has a nVidia chipset on his mobo, and his IDE drivers support individual UDMA mode settings, as well as transfer rate tests.

So, does anybody happen to know of a way I can go back to UDMA mode 5? Is there a generic program I can use to attain such a result? Is there a hack, tool, anything!?!?

I know this question has probably never been asked before, so I don’t expect any answers from you guys… but please know that it would be REALLY appreciated if you could share what knowledge you have on the subject. I’ll keep trying things on my end, but I can only do so much, you know what I mean?

Thank you for reading this unecessarily long post, and thank you for hopefully replying to it!

Hope to hear from you soon,
William

Not sure if this is solution to your particular problem, but read this:

Have you tried altering the settings in the BIOS?

Or, have a look around the HD manufacturers website - often there’s utilities available to alter the DMA mode of a particular drive.

Failing that; what’s the motherboard model? HD? Sound card?? Is it crackling ONLY when there’s disc activity???

Thx jamo, but I’ve actually been to about a dozen sites just like that. :iagree: Everybody seems to know how to turn DMA on/off – but to select which speed? Practically impossible it seems!


#5

Yep, but the only available options my BIOS gives me is which PIO mode to choose – which of course doesn’t even apply to DMA mode. (I tried all possible settings anyway, with no luck.) :sad:

Or, have a look around the HD manufacturers website - often there’s utilities available to alter the DMA mode of a particular drive.

Looked there too… but the only available programs are diagnostics / partitioning programs. No DMA settings to change anywhere.

Failing that; what’s the motherboard model? HD? Sound card?? Is it crackling ONLY when there’s disc activity???

The motherboard is a SOYO (yeah, I know, I need to get a new one based off of this alone!) – model SY-K7VME @ BIOS v2aa4 (the latest I believe)

The HD is a Maxtor 120GB – model 6L120P0 – PATA133

The sound card is a Creative Labs Audigy 2 ZS (w/ 5.1ch surround sound!)


The crackling is evident on EVERY form of audio that plays, from the introduction sound that windows plays when I log on (wav), to the music I play (mp3), to the movies I play (ac3). So the problem I don’t think is related to any specific device, other than the motherboard itself.

I think there’s some sort of incompatibility between my mobo’s PCI bus, and IDE bus. :iagree:

Thanks for helping me out guys! I know there’s a solution out there… we just have to find it!


I HAVE found the program I am looking for BTW, although it’s for Linux and not Windows. :frowning: It’s called “hdparm” – and it allows one to select any specific DMA or PIO mode they feel is appropriate.

Does anyone know where I can find a Windows-based utility out there? I’m looking but coming up empty handed.

If you can find it, there’s a maxtor utility called [B]UDMAUPDT.EXE[/B], which is used to change the DMA modes. Google searching it returns lots of entries to the instructions… but I can’t as yet find anywhere you can actually download it from… it doesn’t seem to even be on the maxtor site :doh:

But, I’d have a read of this too - http://forums.creative.com/creativelabs/board/message?board.id=soundblaster&message.id=71962 :eek:

HOLY MOTHER OF PEARL YOU ARE A GODSENT UK1AND!!!

:bow: :clap: :bow: :clap: :bow: :clap: :bow:

The file you mentioned was actually a part of a a bigger program, called 66to100.exe, which sets the DMA mode to 5 on select Maxtor drives!

Now if there’s one thing I’m good at, it’s finding files! And I found it alright… AND IT FREAKING WORKED!!! Like a charm, I say, like a charm. :iagree:

So, do you have like a PayPal account or something because I have GOT to find a way to repay you for this man!! I am throwing a fit right now I’m so freaking happy!!!

Man this here CDFreaks forum is the best on this planet! Hands freaking down. :slight_smile:

Thank you thank you thank you thank you thank you… and thank you. Problem totally solved. :wink: Besides, I didn’t notice a speed increase from ATA100 to ATA133 anyway… I just got the HD 'cause it was bigger!

OMG thanks again dude… you are so nice!

Glad you’re now a happy bunny with this.

The way you repay someone for any help freely supplied like this is by helping others in future.


#9

Oh I agree… nothing beats the sharing of knowledge. :iagree:

Someday I’ll be in your shoes helping somebody else out!


#10

I’m glad to see you have solved your problem, too. I have this similar problem, but my operation system is 64bit and the 66to100 seems not support the 64bit windows7. So…how should I do?:sad:

Similar is not the same.

What is your exact problem???


#12

i would try to move the sound card out of the that pci slot maybe the slot is shared! to a unshared pci slot and see if it werks with DMA6

I mean 66to100 does not work in windows7 64bit vision even cannot be opened.
I don’t know if I can change the DMA5 mode to DMA6 in windows7. Or is it just because my hardriver does not support DMA6?:rolleyes:


#14

Have a look into the BIOS if possible. The HDD should be autodetected there and if the hdd does support UDMA6 then it should use it too. But that really depends on the HDD itself. :wink:

Also, the specifications of the motherboard chipset should be reviewed. Some Intel chipsets were limited to UDMA-5, where competitors already were on UDMA-6 level. (Which was usually a non-issue since HDDs at that time were not fast enough to saturate the interface).

#16

Thanks for your help!
I followed your suggestion into BIOS.
My HDD is WDC WD20EARX, but I didn’t find any option about DMA support. Just something about ATA Channel or AHCI mode.
The motherboard is ASUS P8H61 PRO.
I have searched webs but seems there’s nothing about it.

I just want to let my HDD working faster. Because it seems always slow down my system running speed. My windows experience index is 5.9 which also is the HDD score. Other scores is more than 5.9.:o
Um…I guess maybe I thought too much. But still, I think there’s possibility of faster speed.:o


#18

I doubt it.

Even the hdd would be faster in theory, you shouldnt underestimate the controller and its overall influence combined with the drivers.


#19

try these link----> http://vip.asus.com/forum/topic.aspx?board_id=1&model=P8H61+PRO&SLanguage=en-us

and on the left side you can read the FAQ maybe u find some usefull info

[QUOTE=doctwingkey;2623449]I just want to let my HDD working faster. Because it seems always slow down my system running speed. [/QUOTE]The speed of a HDD is determined by its “mechanical” properties, like data density of the platters or rotational speed, it is [B]not [/B]limited by the interface (unless it is connected to an extra slow controller, but this is impossible with Sata interfaces.)
If you think your HDD is too slow, buy a faster one or even a SSD.
