That's a "feature" of Windows 9x. Haven't seen anything like that on Linux.

Modern drives have a burn proof thing that basically can stop burning and
restart accurately if the incoming data queue becomes empty. I've only managed
one coaster with my drive (Plexwriter 24/10/40A) and that wasn't due to buffer
underrun. (While simulateously surfing the web, reading email, and
downloading ISOs from ftp.esat.net. Not exactly high load, but enough to test
the IDE subsystem).
