When I read or burn a CD, the CPU works at 100%.
I didn't have this issue in Windows Xp or 98SE.
So when ever I need to burn a CD, the whole system is
laggy. I MUST burn the CD at 8x MAX or the buffers are
messed up and the CD is ready for the trash can!!!
I've installed Windows 2000 on a couple of friends PC's
and laptops because it's really stable for gaming and
working, and they have the same problem...
My System Configuration is:

CD-Rom: Samsung 48X
CD-RW : Plextor 40/12/40A (PlexWriter)
CPU : AMD Athlon 1800+ XP
Memory: 1GB @ 433MHz
 
Go into Control Panel, look under the channels for your
IDE controller and make sure DMA mode is enabled.

Hey Rick, THX! I've found it in the control panel and it
works! Now I can copy CD's on the fly!

What's the difference between DMA and PIO?
In my BIOS list, my CD-Rom shows like a PIO...
 
Simply put, DMA mode allows large chunks of data to be
transferred from IDE devices to system memory without
going through the CPU. PIO mode transfers tiny bits at a
time. If you bring up Task Manager while burning CD's
and compare the two transfer types, DMA mode uses a
very small amount of CPU time compared to PIO.

You should also set the transfer type to DMA Mode 2 in
your system bios. Sometimes it's listed as "PIO Mode 4/
DMA Mode 2", or "UDMA Mode 2".
