Name: John
Many people have read my posts concerning UDMA. I've done every thing I could from toggling with "PIO Mode" and "DMA if available". I've uninstalled and reinstalled both of the IDE Channels and the hard disk, and finally reinstalled Windows XP. All this still no UDMA for for my hard disk. Please please please...HELP!
Info:
Western Digital WD300BB Ultra ATA/100 using 80-pin cable and latest drivers installed for everything: SiS735 Chipset Drivers---> everything all updated.
What motherboard do you have? I assume it's an ECS or Pc Chips board because of that chipset. Maybe a k7s5a or m841 Pc Chips?

Hi,Look in devices,motherboard resources and see if there is a Dma controller listed.If so check properties to see if there is a driver installed.The problem may be there.

Here are some of the standard items on the UDMA checklist.
Make sure you're using an 40-pin/80-conductor IDE cable for your hard drive if you want higher than UDMA mode 3.
Make sure your IDE cable is in top condition. I know it's weird, but they DO go bad sometimes, especially if there's been a lot of plugging in/out of IDE devices. I destroy 80-conductor cables on a regular basis because I'm not very gentle with them, and they seem to be more fragile than 40-conductor cables.
***Make sure UDMA is enabled for that IDE channel in your BIOS. What does your BIOS detect as your drive's transfer mode?
Make sure you don't have a slower device on the same IDE ribbon cable, such as a CD-ROM or older model hard drive.
Make sure you have a busmaster driver installed along with your IDE channels in Device Manager.
That's the standard tosh. If I had to guess, I'd check to see whether the drive's detected accurately in the BIOS first. Then the cable/slower IDE device, THEN OS level stuff.

The WD Diagnostics disk also has a utility on it to check and set the UDMA.
It is called Ultra ATA Manager

I'm currently using everything you have there: New 80-pin cable, UDMA is availabe, setup detects UDMA Mode 5, but like I said before the HD is using PIO Mode. The latest SiS PCI IDE Controllers have been installed. And I have tried using the Data Lifeguard Tools, but somehow, it just pops up the command prompt from DOS and then goes away. If I recall, it's an .exe file and I believe I just double click on. But if there is a right way of using it, then let me know. Otherwise, everything that I have done correctly is not helping improve the HD performance/transfer mode.

Whoops, I believe that was another program. But it did say Ultra ATA Manager. I guess it was different. I'll let you guys know what happens after using the Data Lifeguard Tool. Thanks a lot. I appreciate all the help. Thanks everybody.

Hey Guys, bad news. It didn't work. I went through the installation. I have enabled UATA 100 and it says that the HD now supports up to UDMA 100. It then said that I should shut the computer down for 30 seconds and then boot up. I did so and looked in the properties of the primary ide channel. The HD is still using PIO Mode 4 and now I'm definitely out of clues. Unless there's something else that can be done

Is the hard drive on the IDE channel by itself ?
Meaning, you do not have a slave device like a CDROM or DVDROM attached on the cable as well ?And your motherboard is ATA 100 capable ?

here's some info, a friend of mine, from another forum:

yeah, it's on the IDE channel itself and Ultra ATA 100 capable. One thing I didn't mention about Data Lifeguard was that it said: ULTRA ATA 100 IS NOW DISABLED ON IDE 0. YOUR HARD DRIVE IS NOW CAPABLE OF ULTRA ATA 100.
My question is that why is it disabled on IDE 0? or if that's my problem, how do i enable UDMA on IDE 0?
