Problem with Windows 2000 and UDMA 100

[bjb94]

My Hard Disk Maxtor 45 Go is not recognize by Windows 2000 as a UDMA 100 Hard Drive. It is unable to push it as an UDMA Hard Drive and Windows display PIO Mode. My motherboard is a ASUS CUSL2 with chipset 815.

Help Please

my second hard drive is a UDMA 33 and 2000 recognize it without problem.

i believe that ata100 drives do not have the DMA checkbox enabled in the device manager because they are supposed to be set automatically without needing it.

I am starting to think its a issue with the 815e chipset and win2k since I have the same problem on a Msi 6337 mainboard and Ibm 75 gpx drives. I resorted to putting the Ibm drives on a Promise Ultra 66 to get them to run in udma in win2k. I have a Western Digital ata66 drive that runs fine on the Intel storage controller in Win2k.



PYR WTF are you talking about. DMA is selected under the Ata controllers in win2k and there is no checkmark to enable DMA in win2k and you can enable DMA with ata 100 drives in Win98 and Winme by putting the checkmark in the DMA box for each drive and its enabled.

Have you installed Intel's Ultra ATA Drivers? If not try installing those first. With the drivers Intel provides a Companion program that will identify the drive and tell you what transfer mode you are opperating in. Also, if your ATA33 drive is on the same channel as your Maxtor the fastest your Maxtor will opperate is ATA33.

Ya and good luck getting any CD burning programs to run in win2k after the Intel storage drivers are installed in Win2k. It also did not get my Ata 100 drive out pio mode after the Intel storage driver install.

tho I would have to check the docs, when DMA5 is enabled you dont need the DMA option in windows. it is enabled in the BIOS and automatically implimented in windows. I believe the reason it does not show is because it is setup in a different way. that is similar to when you install a drive on an ATA66 controller card, you dont get the DMA option because it is automatically setup.
