I do not use the factory image of Windows XP + all the utilities IBM preinstall on the machine.

I'm wondering if the setting in BIOS where you set your optical drive speed works. whenever I put a DVD drive on my machine, the copying process is slow, even though I have selected in BIOS the max setting for the read rate, but in Windows the drive does not sound like reading at its max.

Any way I can improve the read speed rate?

It works - but the speed increase is somewhat modest.

Make sure that DMA is enabled in device manager, properties for your IDE controllers (primary and secondary channels), advanced tab. If it isn't enabled change it and reboot.

Supposedly the Read Speed should be 8x for DVD's, but I'm getting 3X max. Do I need to install a certain IBM utility in Windows to make the change in speed work?

I believe I have DMA enabled on Windows, on both Primary & Secondary controllers.

Can't do much about that (speed). Panasonic-based (chipset) optical drives aren't really known for their performance - read or write (but especially suck reading DVD's - single-pressed in particular).

Wait, are you using a regular from the store DVD-Video disc to do tests or DVD-Rs you burned or what? Because the read speeds varies depending on the type disc. Most of the time they just label the drive as:

24x (CD), 8x (DVD)

but fact is DVD-RW and DVD-RAM and in some cases DVD+R/-R and DVD-Video don't read at 8X speeds. It depends on the quality of the disc and therefore the quality of the burn. If there's a lot of error correction then it wont reach 8x. Try out other discs and what are you using anyways? Nero DVDSpeed or what?

I think it doesn't matter. I've tried playing some original DVD9 movies and the movie kinda is slow. If i install a game (San Andreas) it takes several minutes to transfer the files.
