First, find out what your SCSI identifiers for your CD-ROM are (you must be root): # cdrecord -scanbus [SNIP mostly useless info] scsibus0: 0,0,0 0) 'TOSHIBA ' 'DVD-ROM SD-R2002' '1W26' Removable CD-ROM 0,1,0 1) * 0,2,0 2) * 0,3,0 3) * 0,4,0 4) * 0,5,0 5) * 0,6,0 6) * 0,7,0 7) * From this we can see that my CD burner is SCSI 0,0,0. So we'll use that info in cdrecord's dev= parameter. Then use something like this to burn the CDs: # cdrecord -v dev=0,0,0 -data isoimage.iso You may want to specify the speed to burn at if your system can't guess the right speed of your drive, or if burning at your drive's maximum speed tends to produce bad disks.

Use readcd dev=/dev/sgcdrom f=cdimage.iso instead (where /dev/sgcdrom is the SCSI generic device for your CD-ROM drive). Also, use the -dao switch to cdrecord when recording in the first place. Someone else on this list gave me that tip, and it does appear to create a more exact burn of the original image. Of course, IME, when I had trouble doing a read-and-compare of CDs I burned, the discs generally still worked fine. So I'm not sure how much it matters. But it certainly can't hurt. Another compare trick I use is: mount -o loop -r /path/to/original/cdimage.iso /mnt/image diff -qr /mnt/image /mnt/cdrom That will at least verify everything in the regular filesystem is a match. Of course, your problem appears to be with the boot catalog, which is outside the regular filesystem. :-/ -- Ben Scott [EMAIL PROTECTED] | The opinions expressed in this message are those of the author and do | | not represent the views or policy of any other person or organization. | | All information is provided without warranty of any kind. | ___ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

I've used exactly that approach a number of times recently, and had no troubles. Perhaps the difference is bad sectors on the disc, or other copy protection mechanisms that dd doesn't handle well. I'm pretty sure it has something to do with esoteric features of the various Compact Disc specifications. CDs can have multiple sessions, each with multiple tracks. An ISO-9660 filesystem can have multiple namespaces, and there does not have to be a one-to-one match of every file in every namespace. Plus the whole boot catalog thing, which is outside the regular ISO-9660 filesystem, but still part of it. How the heck do you present that as a single /dev/cdrom device? :-) I know it's made a difference with Red Hat Linux CDs (back when there *was* a Red Hat Linux) made from MD5-verified images, so it isn't a copy protection thing. -- Ben Scott [EMAIL PROTECTED] | The opinions expressed in this message are those of the author and do | | not represent the views or policy of any other person or organization. | | All information is provided without warranty of any kind. | ___ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
