win2000, yamaha CRW8824S, adaptec ASPI layer
installed, writing CD-R (tried differend types/layers).
writing fails (with some error messige "error xxx - maybe
buffer underrun) with speeds 4x, 6x, 8x...
then again, sometimes it works.
ah - driver was "generic mmc" as suggested.
drive works fine with WinOnCD though.
