I have two SCSI CD burners, HP CD-Writer+ 9200 1.0e (dev 0,6,0) and PLEXTOR CD-R PX-W4220T 1.04 (dev 0,4,0), and cdrecord 1.9 on FreeBSD 4.4. When I'm starting to burn a CD on the 0,6,0 device while the 0,4,0 burner is already burning, the 0,4,0 fails with cdrecord: Input/output error. write_g1: scsi sendcmd: retryable error CDB: 2A 00 00 04 A6 5A 00 00 1F 00 status: 0x2 (CHECK CONDITION) Sense Bytes: F0 00 03 00 04 A6 F2 0A 00 00 00 00 0C 09 00 00 00 00 Sense Key: 0x3 Medium Error, Segment 0 Sense Code: 0x0C Qual 0x09 (write error - loss of streaming) Fru 0x0 Sense flags: Blk 304882 (valid) write track data: error after 624087040 bytes Sense Bytes: 70 00 00 00 00 00 00 0A 00 00 00 00 00 00 00 00 00 00 It happened two times, so I don't think it's a coincidence with a bad CD. When I start the 0,4,0 device while the other is burning, everything is fine. Also, the buffer fill seems to be OK (min fill 98% after the failure). Any idea what's causing this? Any tips on how to find the problem? Or am I not supposed to burn 2 CD's at a time? (If so, why?) I couldn't find a hint on the cdrecord page. Could it be that I should have recompiled cdrecord when going from 4.4-RC to 4.4-STABLE ? It's often necessary after an upgrade, but I'd say that the difference from 4.4-RC to STABLE is minimal. Well, when I try to reproduce I'll use rewritables ;-). Karel. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
