Steve Scrimpshire Posted May 8, 2003 Report Share Posted May 8, 2003 If I use scsi emulation so that I can burn CDs/DVDs by adding hdd=ide-scsi to my append line in lilo.conf, then I am unable to mount my /dev/scd0 (DVD burner) [root@localhost omar]# mount /dev/scd0 /mnt/dvd /dev/scd0: Input/output error mount: you must specify the filesystem type [root@localhost omar]# mount -t udf /dev/scd0 /mnt/dvd mount: wrong fs type, bad option, bad superblock on /dev/scd0, or too many mounted file systems (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?) [root@localhost omar]# mount -t iso9660 /dev/scd0 /mnt/dvd mount: wrong fs type, bad option, bad superblock on /dev/scd0, or too many mounted file systems (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?) Here are all the possible ways I've tried to set up /etc/fstab: /dev/scd0 /mnt/dvd auto user,iocharset=iso9660,umask=0,sync,exec,codepage=850,noauto 0 0 0 0 /dev/hdd /mnt/dvd iso9660 noauto,owner,ro 0 0 /dev/scd0 /mnt/dvd udf,iso9660 user,iocharset=iso8859-1,umask=0,exec,ro,noauto 0 0 /dev/scd0 /mnt/dvd udf,iso9660 user,noauto,ro,unmask=0 0 0 What am I missing? It's got to be something simple. If I don't put hdd=ide-scsi in my append line, I can mount them just fine.

Cannonfodder Posted May 8, 2003 Report Share Posted May 8, 2003 Only thing I can recall offhand is someone suggesting you set it up as a cdrom and tell the software that its a dvd. I know that probably won't help but its just something I read somewhere either here or in alt.os.linux.mandrake. There's a thread going on there on DVD's, might want to read..

Steve Scrimpshire Posted May 8, 2003 Author Report Share Posted May 8, 2003 Thanks. That's not really the problem. My other drive is DVD ROM and I can mount any disk fine in it. If I make my second DVD Burner's options look identical in /etc/fstab, it won't mount. If I unload all the scsi-emulation modules, I get this: [root@localhost omar]# mount /dev/hdd mount: /dev/hdd is not a valid block device [root@localhost omar]# ls -l /dev/hdd brw-rw---- 1 omar cdwriter 22, 64 Aug 30 2001 /dev/hdd [root@localhost omar]# ls -l /dev/scd0 lrwxrwxrwx 1 omar cdwriter 8 Apr 30 03:13 /dev/scd0 -> /dev/hdd [root@localhost omar]# mount /dev/scd0 mount: /dev/scd0 is not a valid block device [root@localhost omar]# mount /dev/sr0 mount: /dev/sr0 is not a valid block device [root@localhost omar]# mount /dev/hdd /mnt/dvd mount: /dev/hdd is not a valid block device I've searched this site and scoured the web. Yes, I have support for scsi cdroms compiled as a module, as you can see. Thanks for the assistance, though. I'll try anything. Quote Link to comment Share on other sites More sharing options...
Steve Scrimpshire Posted May 8, 2003 Author Report Share Posted May 8, 2003 Hmmmm. I discovered that there is a new scd0-1 in my /dev/ directory: [root@localhost dvd]# ls -l /dev/scd0-1 brw-rw---- 1 omar cdwriter 11, 0 Aug 30 2001 /dev/scd0-1 So, I added this: /dev/scd0-1 /mnt/dvd auto user,umask=0,noauto,unhide 0 0 to my /etc/fstab and guess what...I can mount /dev/scd0-1 Interesting. Now to try rebooting and see what happens. Quote Link to comment Share on other sites More sharing options...
Steve Scrimpshire Posted May 8, 2003 Author Report Share Posted May 8, 2003 Wow, it still works after a reboot. [root@localhost omar]# ls -l /dev/scd0 lrwxrwxrwx 1 omar cdwriter 8 Apr 30 03:13 /dev/scd0 -> /dev/hdd [root@localhost omar]# ls -l /dev/scd0-1 brw-rw---- 1 omar cdwriter 11, 0 Aug 30 2001 /dev/scd0-1 Cool! Now I'm testing the burning. I can only choose to read from the burner in XCDroast, probably because I don't have my other drive with scsi-emulation for fear of not being able to mount it. Later I will try scsi-emulation on that drive and see if I can mount it and also use it to read directly from CD/DVD to burn to CD/DVD.

Guest Dr-Proton Posted May 14, 2003 Report Share Posted May 14, 2003 I'm sorry.. buy *why* do you need to reboot? Quote Link to comment Share on other sites More sharing options...
Steve Scrimpshire Posted May 14, 2003 Author Report Share Posted May 14, 2003 I don't need to reboot. My system is dual boot and sometimes I've made changes that don't stick after I've rebooted back and forth and was just testing to make sure this was not the case this time. I should've been clearer.

Guest fubar::chi Posted May 14, 2003 Report Share Posted May 14, 2003 probably because I don't have my other drive with scsi-emulation for fear of not being able to mount it.

Steve Scrimpshire Posted May 15, 2003 Author Report Share Posted May 15, 2003 It works. I meant to come back here and post a follow up. It only didn't work before on my DVD burner because I was trying to use the wrong device (/dev/scd0 instead of /dev/scd0-1). Quote Link to comment Share on other sites More sharing options...
