Hi Everybody Has anyone ever had any success writing CDs with a Linux laptop? What's the best solution: parallel port, USB or PCMCIA IDE? I'd be interested to here of anyone's experiences with this. Cheers M -- Matthew S. Smith Private : http://www.mss.cx Business: http://www.kadina.cx
I don't own a laptop but I'll share my experiences trying to get my ATAPI PleXWriter 8/4/32 working. SuSE 7.1 recognized it as hdd. As hdd my SB PCI512 could play music CDs and I could access CDs on the drive. BUT, xcdroast would not recognize it because it wasn't scsi. So, I added scsi emulation to the kernel and an hdd=ide-scsi line to lilo. Now, I can burn CDs but I can't play music CDs, Also, the scsi emulation is intefering with my parallel zip250 installation, which worked when my PleXWriter was hdd. I get two scsi devices recognized at boot. And while my PleXWriter is scd0, it appears that scd1 isn't connecting to the Zip250 using mount -t iso9660 /dev/scd1 /zip or mount -t vfat /dev/scd1 /zip (because the iomega zip disk is vfat.) I'm between a rock and a hard place. If I were to design my beast again I would require both the PleXWriter and the Zip250 to be scsi devices, with the scsi card loaded into the kernel at boot. jlk On Monday 26 March 2001 20:14, Matthew Smith wrote:

I'm talking off the top of my head, because I haven't got any scsi-emulated devices to look at right now. Are these scsi-emulated devices named/numbered like IDE and real scsi devices? If so, scd1 would be partition 1 on device scd, not a separate device, right? With IDE, devices are hda, hdb, hdc, hdd With real SCSI, they're sda, sdb, sdc, sdd, etc. I just sold my external scsi ZIP drive, but the fstab entry, which is all that remains in memory of it, reads: /dev/sda4 /zip auto noauto,user 0 0 It was the only device on the SCSI bus, hence 'sda'. For some strange reason, the preformatted media comes with a single large partition, but defined in the fourth position in the partition table, hence 'sda4'. What is the equivalent naming/numbering scheme for the scsi-over-whatever emulated devices? -- Rick Green "I have the heart of a little child, and the brain of a genius. ... and I keep them in a jar under my bed"

Jerry/Rick, Here is my experience with SuSE 6.3 and the latest 2.2.x suse kernel, FWIW. I guess numbering depends a little on what order your modules load. But it seems that emulated-scsi numbering is just like the numbering of real SCSI devices. In my case I have a box with a cheap ISA SCSI card driving a real SCSI scanner, and a cheap IDE CD-Writer using kernel module ide-scsi emulation.

You might find it confusing (as I do) that my kernel has numbered both devices "0" but this is how it is. It works. Tim Gerla's tcd (or gtcd) program has no problem playing audio CDs. I am not sure how xcdroast works, but I have successfully done 4X burns using the commandline utility 'cdrecord'. I don't use a Linux /dev file directly. Instead I gave cdrecord the SCSI address of the CD-RW directly on the commandline. ide-scsi created a virtual scsibus1.

/dev/scd? is for SCSI CDs /dev/sd? is for SCSI hard drives /dev/sg? is for 'generic' SCSI devices, like scanners, etc. You should be able to mount the zip drives as /dev/sda4 (for some only-partially-understood reason).

I'm also experiencing some wierdness with my set up. I can read a data cd from the ATAPI CD but can't read an audo cd with it. No big deal I suppose, but it would be nice to just use the ATAPI as a source drive and the Yamaha 4416 SCSI as the destination drive.

Yup, I think that the IDE interface is OK for HD's, but gets very messy when you try to add other devices. I think that SCSI simplifies things immensely, and the devices are also easier to port between different machines. ---------------------------------------------------------------------- John Karns jkarns@csd.net

I'd recommend PCMCIA SCSI. In this way it is irrelevant whether you're using a laptop or desktop, or even what OS platform you're using. I've done this with a Yamaha 4416 CDRW and an AHA1460 PCMCIA card. ---------------------------------------------------------------------- John Karns jkarns@csd.net
