I have the same CD-RW drive (Yamaha CDRW-4260), running cdrecord 1.6.1 on -current. I have no problems with burning whatsoever. I never run cdrecord with any special priorities (nice, rtprio, etc.). On the contrary, it always runs with X running, and Netscape, mp3 player, and other miscellaneous applications are sometimes open. Never any buffer overruns or anything similar, I've never even noticed the fifo dip below 95% full! John, as for your error, I have never seen it before but it looks like it writes the data fine and then chokes on fixate...nice -anything wouldn't affect this as it's not a buffer overrun but some kind of real error. How many times have you tried it? Maybe the media is faulty? Try a different brand of CD-R media and see if you get the same error? Al, as for your error, I've been using RW media with cdrecord, -current, and the CDRW4260 ever since I got it. What's the problem you're having? Maybe you're forgetting that a) you need to blank CDRW media before recording onto it, cdrecord blank=all or b) the drive writes RW media at 2x, so set speed=2. > -Alfred > > > > > Oh well, > > Thanks! > > John > > > > Fixating... > > cdrecord: Input/output error. close track/session: scsi sendcmd: retryable error > > CDB: 5B 00 02 00 00 00 00 00 00 00 > > status: 0x2 (CHECK CONDITION) > > Sense Bytes: 70 00 04 D1 C0 00 00 0A 00 00 00 00 09 01 00 00 00 00 00 00 00 08 00 00 00 00 00 00 08 00 01 06 > > Sense Key: 0x4 Hardware Error, Segment 0 > > Sense Code: 0x09 Qual 0x01 (tracking servo failure) Fru 0x0 > > Sense flags: Blk -775946240 (not valid) > > cmd finished after 41.576s timeout 480s > > Fixating time: 43.587s > > cdrecord: fifo had 9194 puts and 9127 gets. > > cdrecord: fifo was 0 times empty and 9126 times full, min fill was 98%. -- ________________ ___________________________________________ / Nathan Dorfman \ / "`IE4 brings the web to UNIX'? *laughing* / nathan@rtfm.net \/ Isn't that similar to Ronald McDonald bringing / finger for PGP key \ religion to the pope?" -Jamie Bowden To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
