ATA 100 Hard Disk problem

[heeroman]

My hard disk is Maxtor 5T020H2 7200 rpm ATA 100. In Windows 2000 it is recongized as " Maxtor 5 T020H2 SCSI Disk Device ". Shouldn't it be a IDE device?

Moreover, I've heard that Windows 2000 does not support ATA 100, is it true? How can I know if my hard disk is working in ATA 100?

I've read this page " http://support.microsoft.com/support/kb/articles/q260/2/33.asp ", but the file doesn't suit me as I am using Traditional Chinese version.

what did it do in win 98? Are you certain it isnt a SCSI drive in the first place?

My short venture into windows 2000 found both my hard drives listed as SCSI. Seems to be a common problem that a driver update may soon or has fixed.

To test ATA100 try HDTach, if it bursts over 66Mb/s then it's working at ata100. Eg the last time I used HDtach ATA100 burst off the scale at 80mb/s.

I think that its normal for win 2k to see your ata 100 as scsi, it detects mine as scsi. My drive is ata 100 and it works perfectly fine in win 2k, also remember that hard drives right now can not sustain speeds to use the ata 100 to its potential, the reason why there is not a significant performance gain between 66 and 100, so don't worry about it be happy

heeroman, I jusk installed this same Hard Drive yesterday on a machine with Windows 2000 and I hooked it up to the secondary IDE controller and it runs at UDMA speed and and is identified correctly But it was identified as a Maxtor SCSI device when hooked up to the Promise controller.
Performance when on the Promise controller was terrible. My Sandra benchmarks on the IDE controller
are over 24,000.

What motherboard and controller are you using?

If it's running right, the controller should report dma5 not 4 for the drive.

Where does it show you where it shows udma 5 or 4? But my IBM deskstar raid 0 setup shows it as scsi also. Thats really annoying and I swear my performance is affected, because my hard drive score in sisoft sandra was around 20000

Well Windows 2000 doesn't have ATA/100 support right now, it's being implemented into SP2, and if your HD is connected to any controller even an on-board Promise or PCI, it will detect as SCSI.

SAY WHAT? My Maxtor 5T020H2 is most definately not detected as an SCSI device in my Windows 2000 machine.

If you have an onboard controller...ie. promise, it should show up as a SCSI device even though it is an IDE.

There is also a hot-fix on Microsoft's site (if you trust their hotfixes) that will temporarily fix Win2000 not running ATA 100 drives at ATA 100....it's hotfix Q260233 (Support for ATA (Mode 5) in Windows 2000).
I haven't set up my new board/system yet to try this, but I shold have it running by the end of the week and can post an update.

If you would rather wait for SP2 I heard that it should be out somewhere near the end of this month, beginning of April.

I have a beta of it, but am VERY hesitant to install MS Beta's on any non-test system.
