Default Slow Copying On XP Almost Fixed But Not Quite Help!!

sponsored links

I have recently converted to XP Pro from WIN 2K Pro & the copying time for my lite-on 24x writer went from approx 4 mins to 7 mins a disk.

Also whilst copying the machine is now really dragging its heals if I use any other programs.

Using win 2k the buffer used to stay at an almost constant 98% now it often goes to 100%, also in task manager the cpu is running at 95-100%.

I had the machine configured with hard drive as master & dvd-rom as slave on IDE1, with the writer on its own on IDE2.

When I went into device manager to check DMA settings for primary IDE, e primary device 0 is set as follows:
transfer mode: DMA if available
current transfer mode: ultra DMA mode 5

For device 1 the detection mode is set to auto & the current transfer mode was set to PIO only, I could not change this so to get around it I put the reader & writer on IDE 2 which showed the transfer mode to be ultra DMA mode 2 this speeded the copying up to just over 4 minutes for a disk( now changed to a 40x Lite-on writer using 32x Datasafe media)

The primary IDE now shows device 1's transfer mode to be not applicable.

How do I set my reader & writer up on different IDE's & enable DMA on both?

My hardware is as follows:

EPOX8KTA3+RAID, 1,33mhz Thunderbird CPU
Maxtor 60gb 7200 ata133
384mb of p133sdram
Lite-onltd163d dvd rom drive & Lite-onLTR40125S writer
Soundblaster 5.1, GE Force2 mx400 64mb

I have almost exactly the same setup as you, and did not see any noticeable performance decrease while burning after upgrading to XP from 2K.

What I would suggest would be to seperate your IDE devices so they are all on completely different channels.

Ensure your RAID is set on in the bios and put your DVD on one of the raid channels as a master.

This may help.

Is DMA also enabled for all drives in the BIOS?

On some boards there is this option, worth checking I guess.

didn't think you could put a cdrom/dvdrom based unit on a raid channel?
