ASC ADh indicates a buffer underrun. ASC 34h indicates an absorption control error, caused by laser power clipping. According to Philips, this is normally either a result of bad media or a defective unit. The cdrecord log you gave confirms that. I'd try new media from a different manufacturer. Since you got the buffer underrun, I'll add FWIW that I would try burning a CD-R at single speed. With my CDD2600 under a 1542CF, using wormcontrol and dd (the burncd script from examples), I've had the best luck using dd with obs=32k, and no team. YMMV. If you have a system a different OS availible, it wouldn't hurt to move the CD-R there and try it. However, from the reports of your errors, I don't think this is OS-related. Nevertheless, since Philips is 12 weeks backordered on RMAs for this unit, it's probably worth checking out. > Here is the output of dmesg: > worm0 at scbus0 target 5 lun 0 > worm0: <PHILIPS CDD2600 1.06> type 5 removable SCSI 2 > worm0: Write-Once I tend to put the worm at id 6 myself. (In your case, it makes no difference, but...)
