I upgraded from Edgy to Feisty and was able to use my two CD-Rom drives successfully. I then reinstalled Feisty from scratch and had two problems. The first is that /etc/fstab mentioned /dev/hdc and /dev/hdd, but those devices don't exist. I updated /etc/fstab to refer to /dev/scd0 and /dev/scd1:
[EMAIL PROTECTED]:~$ cat /etc/fstab # /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 # /dev/hda1 UUID=a6f5a82d-25c3-4497-9603-fe5ad2c54fd2 / ext3 defaults,errors=remount-ro 0 1 # /dev/hda5 UUID=e9c7490a-9474-4e80-8c67-e7d367cabdc8 none swap sw 0 0 /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0 /dev/scd1 /media/cdrom1 udf,iso9660 user,noauto 0 0 /dev/fd0 /media/floppy0 auto rw,user,noauto 0 0 /dev/sdb2 /mnt/b ext3 user,noauto 0 0 /mnt/b/backups/hda1-20070528.img /mnt/oldhome ext3 loop,user,noauto 0 0 [EMAIL PROTECTED]:~$ This gave me access to /media/cdrom1. But I still can't use /media/cdrom0, my CD-Rom burner, when I'm booted into Feisty. It looks like quite a low-level problem: [EMAIL PROTECTED]:~$ sudo hd /dev/scd0 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00005000 [EMAIL PROTECTED]:~$ (The CD in the drive when I ran this command was a Feisty desktop CD.) dmesg includes this: [ 731.533053] sr 1:0:0:0: SCSI error: return code = 0x08000002 [ 731.533059] sr0: Current: sense key: Hardware Error [ 731.533062] Additional sense: Logical unit communication CRC error (Ultra-DMA/32) [ 731.533069] end_request: I/O error, dev sr0, sector 96 [ 731.533072] printk: 2 messages suppressed.

This tells me that KDE knows a CD has been inserted, but can't read the root directory. I've attached the output of `lspci -vv', `lspci -vvn' and `lshw', all run as root. The CD-Rom writer that doesn't work is the LITE-ON device shown in `lshw'. Many thanks for looking at this. Please let me know if I can do any more to help diagnosis. ** Attachment added: "Output of `lspci -vv', `lspci -vvn' and `lshw'" http://launchpadlibrarian.net/8107420/diags.tar.gz -- CDROM drive no longer working, unable to mount. https://bugs.launchpad.net/bugs/94119 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
