ATA 133 not working...

[kyle1745]

I have just purchased a new Maxter hard drive and it is ATA133. For some reason it will only run in DMA 5 or ATA 100. I am using a ASUS A7V8X-X motherboard that does support it. Any ideas as it does show in the bios as DMA 6.

I have also tried the following:
1. Removed reg settings to force windows xp pro to redetect the drive
2. uninstall and reinstalled the IDE drivers
3. Run it as the only drive connected to the box on both IDE channels
4. Tried the new cable that came with he drive and an old one


Any ideas?

i wouldn't worry - too much,
ata133 is only a theoretical max speed of 133, same as ata100 is theoretical.

You would probably realise a 5% increase or so if you did managae to enable ata133.

If you have tried everything else, then it would need a bios upgrade probably

I agree its not that big of jump, but a lot of little bits add up. The bios sees it at DMA 6, so I don't think it is the bios and it is up to date.

maybe the chipset drivers need to be upgraded - do this, then if still no joy, then get the latest sp

Let us know how it goes

You are unlikely to realize any benefit from running at 133 (the 5% mentioned above is wishful thinking - I'd be surprised if the difference was detectable even on synthetic benchmarks) - most ATA drives can't even make a true 50MB/sec on a good day. It's basically a big number that Maxtor came up with for marketing purposes - not an industry standard. ATA 100 is the highest real PATA standard.
.bh.

AGREED

Its a bit more than 5%, but thats not the point at all. The point is both devices I have support it and at the hardware level the drive is seen as DMA 6. The problem is that windows does not. So rather than debate the speed issue does anyone have any ideas? As already stated the systems was up to date along with the bios.

Also I get 66MB/sec already just at 100 by the way. With bursts to just under 90.

 

[montag451]

have you tried the latest sp?

Go to the microsoft site, and see if they have any patches - sometimes one revision of mobo doesn't work correctly in sync with certain version of windows whilst using specific hardware!!!!!
See what i mean - do a search on ms. Spend some time there

SP2 fixed it though it was not listed in MS documents as a fix. I had been waiting to load SP2 on this box as when I did the first time it had some major issues.

The average read speed did not increase much and is arounf 60-66MBs, but the burst is up around 100-110MBs. So not too bad, thanks for the ideas,
