CDRW: can play or write, but not both!
I'm having some trouble with my CDRW.
I discovered earlier this evening that I could not access it with cdrecord -scanbus. I googled the error message, and found some help that fixed the problem. I added the line `alias scsi_hostadapter ide-scsi` to /etc/moduls.conf and added `append="hdc=ide-scsi"` to lilo.conf I then rebooted and was able to burn CDs. yay! unfortunately, I then found myself in a situation where I could no longer mount the CDs. I did another google search and concluded that I would have to change the line in /etc/lilo.conf to `append="hdc=sr0-scsi"`. And this worked. I could mount CDs. but now I cannot burn again! cdrecord -scanbus gives me the old: # cdrecord -scanbus Cdrecord 2.00.3 (i686-pc-linux-gnu) Copyright (C) 1995-2002 Jörg Schilling cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver. cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root. cdrecord: For possible transport specifiers try 'cdrecord dev=help'. Help! what's going on with this? |
When you configure the writer for SCSI emulation your device ID for the drive changes to /dev/scd0. You need to change the /etc/fstab entry for the writer to reflect this change.

ok, so now I changed the /etc/fstab line:
/dev/cdrom /mnt/cdrom iso9660 noauto,users,ro 0 0 To look like this: /dev/scd0 /mnt/cdrom iso9660 noauto,users,ro 0 0 Now, when I run cdrecord -scanbus I get the error message: cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver. cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root. cdrecord: For possible transport specifiers try 'cdrecord dev=help'. and I can't even mount the cdrom drive anymore!!! I get the following errors: # mount /dev/cdrom mount: can't find /dev/hdc in /etc/fstab or /etc/mtab # mount /dev/scd0 mount: /dev/scd0 is not a valid block device audio CD's still play, though this change seems to have been for the worse overall. I'm undoing the chagnes to fstab until I find a better fix :( |
