I used to be able to burn CDs, but a few days ago, while I was writing some backups, it stopped working. What answers to previous questions about this problem I could find blamed it on userland and kernel being out of synch, which isn't my case, so I thought I'd ask here. Has anyone else had this happen? dmesg shows that the CB burner is still recognized: ata1-master: two atapi devices on this channel, no DMA acd0: CDROM <CREATIVE CD4830E> at ata1-master PIO4 ata1-slave: two atapi devices on this channel, no DMA acd1: CD-RW <IDE128 CDWriter> at ata1-slave PIO4 I have /dev/cdrw symlinked to /dev/acd1c, and I used to have no trouble with burncd. This would work fine if I had an ISO image ready: burncd -v -f /dev/cdrw data burn.iso fixate But now, it says: burncd: ioctl(CDIOCSTART): Device busy truss shows this (in part): open("/dev/acd1c",0x2,00) = 3 (0x3) ioctl(3,CDRIOCGETBLOCKSIZE,0x804c2bc) = 0 (0x0) ioctl(3,CDRIOCWRITESPEED,0xbfbff1dc) = 0 (0x0) open("burn.iso",0x0,00) = 4 (0x4) fstat(4,0xbfbff110) = 0 (0x0) adding type 0x08 file burn.iso size 546048 KB 273024 blocks write(2,0xbfbfe9d8,61) = 61 (0x3d) ioctl(3,CDIOCSTART,0x0) ERR#16 'Device busy' Usually, when I put a blank CD-RW into the drive, the light would blink a few times, then stay on. Now, it blinks and then goes off. Rebooting makes no difference. I looked around and saw some other people had had this problem because their kernel and world were out of synch, but mine aren't. I even made sure by cvsupping and rebuilding the world and kernel, and now I'm up to 4.9-RC as of last weekend. It didn't help. Any ideas? It wouldn't be that the drive broke, would it? I assume it wouldn't be seen on boot if it didn't work. Thanks for any tips. Bill -- William Denton : Toronto, Canada : http://www.miskatonic.org/ : Caveat lector.
