Question on uncached speed for hard drive.

[Willie2]

I added a second hard drive 10G to my system. The original 6G is still there.It was done at a shop.The new one runs at 7700rpm while the old runs at 5600rpm I have 126meg of 100mhz ram on winME and Athlon750mhz with Asus A7V MB.I checked ,at PC PitStop and found that my fast drive had an uncached transfer rate of 1.48 MB/S. In comparison with other similar systems at 2.91 MB/S, mine is about half the speed. What is wrong? Any help would be appreciated.:Q

7200RPM; not 7700RPM.
5400RPM; not 5600RPM.
128megs, not 126megs.



Now, to answer your question, this could be that DMA is not enabled for the drive. Press Winkey+Pause click Device Manager, click the + by your hard disk, then double click each disk. the 7200RPM drive (at least) should have DMA enabled. If not, enable it and reboot.

If it doesn't "stick" after you reboot, then I suggest you flash your BIOS to the latest NON-beta version (www.asus.com will have the bios file). If you're not comfortable doing this, have the store "finish" the job for you, they really should have done that for you anyway.

Man were you ever right on!Neither drive had DMA ckecked.I checked them and got a warning sign stating that the settings might not take.After re booting they took.
You know after adding winME and SB pci 521 I could not play a DVD without crashing. Before, I could.I moved cards around to force IRQ changes to no avail. Any suggestions? I could pull the Realhollywood plus and go soft DVD.
Thanks for your help

If you can change the IRQs of the device through the System Properties/Device Manager (Winkey+Pause), then try that, get your IRQs under control (you might find SiSoft Sandra helpful here, which you can get for free via www.google.com search for "SiSoft Sandra&quot

If the Device Manager doesn't let you change the IRQs, you might have to go into the BIOS (when the computer first turns on, press "Delete" usually, or whatever key it says, it should say on the screen). Here you can "force" particular PCI slots to particular IRQs.

Hope that helps...
