I burned 32 audio cds in one night for a co-worker (a whole spindle!) Anyway, I blanked a cdrw last night, and it went perfect as i hoped. Just to make sure I'll blank another cdrw right now. --snip-- ryan@ryan:~% burncd -f /dev/acd0 blank blanking CD - 99 % done ryan@ryan:~% --snip-- Well seems to be in order still, I'll be sure to post results if I ever see anything otherwise. FWIW, I have a 40x12x48 Liteon burner, (burnproof, never ever had a buffer underrun) and I've never had ANY problem with it making coasters in the 3 years I've had it. Used it in linux, windowsxp and freebsd. The only coasters are the ones I force upon myself when I over do it trying to stuff stuff onto a cdr (720mb on a 700mb cdr anyone?) - ryan By the way, this is on FreeBSD 5.3-RC1. No DMA settings have been disabled, and its an asus nforce2 motherboard.
