Hi, recordable CDs are the only affordable backup medium for a Linux system (at least for private use) - therefore it's a key technology for Linux. I've been using Unix for over 10 years now and Linux for several years at work where I have expensive DAT recorders for backup. Now for private use I am on my own since all seems to depend on a single person (Joerg Schilling) who seems to dislike Linux very much. His only comment to my bug report was: get a reasonable operation system. Now I do understand why most people prefer Windows, a fact I couldn't understand until recently. (It took me just a few minutes to make my first CD) On Linux I've read several HowTo and similar things, I've reconfigured my 2.4.0 kernel until cdrecord -scanbus recognizes my 2 CD drives. cdrecord is able to read the manufactor information on the blank CD and it's able to eject the CD, so in principle it could access the drive. But then I get only a scsi error message. Perhaps someone (other) can give me a hint where to start to investigate the problem. For those who can get some information out of cdrecord's error log, I've appended it. My drive seems to be (it has a sticker 'HP CD-Writer Plus') Hewlett Packard LT9340 ???
