DVD drive interrupt problem

    Each time I rip a CD/copy data from a cd/DVD my laptop slows right down. The interrupts consume the cpu and the mouse judders across the screen for the duration of the process and if i'm playing music it slows down to half speed.

    Ripping CD's seems to take longer then it did, and copying the contents of DVD off it to the hard drive takes about an hour.

    Attached is a screenie of process explorer and of the DVD drive in device manager. Everything appears okay, but obviously its not!

    Acer Aspire 5020 AMD Turion64, 512mb ram blah blah Win xp home. DVD drive is a slot loaded Matsu****a UJ-845D. I have daemon tools installed, but it isn't running.

    Any ideas of what it could be?

    Google "DMA".

    Edit: More information copy /pasted from another thread:

    Is your hard disk by any chance running in PIO mode? If so change it to DMA.
    to check, open up device manager and go to properties on your IDE channels, and then to the "advanced settings" tab.

    Primary IDE is in DMA mode

    Secondary IDE was in pio mode, so i changed it to 'DMA if available' but its still stuttery. Will reboot to see if that fixes it

    Mmmmm that didn't work :confused:

    Rebooted and tried playing a CD and its still stuttery. I mean thats definetly what it is the DMA (We learned it in OS last semester! Should have looked around a bit more in control panel for the option!)

    Device is in 'DMA mode if available' though its actual mode is pio :confused:

    Was working grand a few weeks ago, only realised something was up last week when it took an hour or so to copy data across

    I'm pretty sure you can force DMA mode on it. No self respecting drive should be PIO mode only. Is it still under warranty?

    Still under warranty yeah, but I need it too much to be sending off.

    Nero InfoTool says that DMA is off. Anyway to force DMA on, control panel just gives two options 'DMA if available' and 'pio mode'
