Some questions that need to be answered

What Interface is it ?
IDE/SCSI/USB/Firewire/SATA

If USB is the drive USB 2.0 and does your motherboard does your motherboard
have usb 2.0 and further more does your distro supports that usb 2.0chipset.

if IDE what type of cable are you using. are you using a UATA 133 rated
cable

Scsi which card are you using

Firewire No questions

Anyway I seen this problem when the cd burner can not seem to fill its
buffer. Which causes alot of I/O commands back and forth eating up memory
and processor time.
