Hi everybody! I' ve got this problem....I have a Toshiba CD-W / DVD-ROM, but my system recognizes only the DVD-ROM and not the burner...additionally, whenever I mount it, it says it can be mounted only in reading mode!! the output of cdrecord --scanbus is this:

In the fstab I' ve this:

PLEASE HELP! thanks a lot, Marco

Have this with your boot options. hdd=ide-scsi

This should enable scsi emulation. Whats happening is that your cdburner is not recognized because scsi emulation is not on. Also, try changing /dev/scd1 to /dev/sr0 in your fstab file.

Thanks for the quick reply! I've tried what you said...but nothing changed :-( I also noticed that at startup my CD-W / DVD is recognized as /dev/hdc, and that I get an error message regarding line 8 in fstab (the cdrom!) and saying that the line is bad!!! Any ideas why?

post your entire fstab file and i'll take a look at it for you. I'm pretty sure its the fstab file. Also, type ls -l /dev/cdrom , ls -l /dev/scd1 , and tell me what you get. Is the cdrw/dvd the only cdrom you have installed?

Ok...this the fstab:

LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda5 swap swap defaults 0 0
/dev/hda6 /osshare vfat umask=000 0 0
/dev/sr0 /mnt/cdrom udf,iso9660 noauto,unhide,exec, rw 0 0

then...

root@host68 root]# ls -l /dev/cdrom
lrwxrwxrwx 1 root root 9 7 nov 13:31 /dev/cdrom -> /dev/scd0
[root@host68 root]# ls -l /dev/scd1
brw-rw---- 1 root disk 11, 1 30 gen 2003 /dev/scd1
[root@host68 root]#


and yes, this is the only device I have on my laptop...

Try this: First, copy your fstab file to fstab.bak (need to make a backup just in case). Next, replace your fstab file with this below:

LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda5 swap swap defaults 0 0
/dev/hda6 /osshare vfat umask=000 0 0
/dev/cdrom /media/cdrom auto ro,noauto,user,exec 0 0

before booting, type this during your lilo boot: hdd=ide-scsi

Let it boot. I assume you have the cdrtools installed right? try downloading xcdroast www.xcdroast.org, and install it. The latest RPM should provide you with all dependencies. When you login to your system, loging as root.

OOPS!!! My bad, use this for your fstab file, sorry:

LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/shm tmpfs defaults 0 0
/dev/hda5 swap swap defaults 0 0
/dev/hda6 /osshare vfat umask=000 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
proc /proc proc defaults 0 0
usbdevfs /proc/bus/usb usbdevfs noauto 0 0 0
/dev/cdrom /mnt/cdrom auto ro,noauto,user,exec 0 0

Tried! Nothing...at least...I don't know how I can check if it's working, for now I have the same problems as before....:-(( One question though, does it matter if I' m booting with GRUB ( I used hdd=ide-scsi anyway)? I also checked and I do have XCDRoast, but I don' t have the error anymore in fstab (I' not really sure why!).

Were is your CDRW / DVD drive connected, /dev/hdc or /dev/hdd? You need to change grub to where ever the drive is actually located.

It appeared that cdrecord was recognizing the drive correctly. It also appeared that everything was working as /dev/hdc and your device was /dev/cdrom which was linked to /dev/scd0. The drive becomes /dev/scd0 due to SCSI emulation.

So what are you really trying to do. When you mount a CD it will be configured as read only. You do not mount the CD prior to writing and in fact can not mount a blank CD. Does cdrecord --scanbus still detect the drive correctly? When writing, cdrecord uses the actual device and does not care what is in the fstab file.

To test you will need to burn a CD.

Right on Michaelk! I could actually burn a CD!! Thanks a lot!!
