Thanks to all who advised me about getting a CD burner earlier! I settled on an HP SureStore 6020i. I'm noticing two problems with it. The first (rather unimportant, but I felt it might hold a clue to the other one) is that I can't seem to mount a CD-ROM: # mount -t cd9660 /dev/worm0 /cdrom0 cd9660: Input/output error I noticed Jean-Marc Zucconi's recent post to freebsd-hackers about a problem that looked similar to this, but when I tried to apply the patch he posted, it had already been applied--apparently that fix is contained in -current as of a few weeks ago? The second problem is that I can write short tracks with cd-write, but if I try to write longer ones, I invariably get an infinite stream of: /kernel: worm0: oops not queued /kernel: biodone: buffer already done and the write starts failing. This is with cd-write from the ports collection running at 1x (2x has similar problems) with an Adaptec 2940 SCSI controller. Testing with an audio track shows that when it does this, *some* data still reach the disk, but only a small percentage of it. The resulting CD thus "skips" because some correct data were written, then a lot of stuff got dropped on the floor, then it resumed writing with data that should have come a few seconds later. If anyone has any suggestions, I'd love to hear them! Or else, failing that, a "take it back to the store and get XYZ cd burner instead; it works better" would also be helpful :> Thanks a lot, ~Ben
