Guest ndeb Posted March 15, 2003 Report Share Posted March 15, 2003 There is also a duplicate entry for my CDRW. One is for IDE and the other as SCSI. Can this be removed? http://www.xcdroast.org/xcdr098/faq-a13.html#28 here is also the pertinent line from my lilo conf. : append="devfs=nomount hdc=ide-scsi failsafe" Can u change it to append="devfs=mount hdc=ide-scsi" and then run lilo -v and then reboot and then check if things are better ?

Guest ekp Posted March 15, 2003 Report Share Posted March 15, 2003 I was mistaken this is the line that pertains to my system. The other was labeled "failsafe" append="devfs=mount hdc=ide-scsi" Quote Link to comment Share on other sites More sharing options...
Guest ndeb Posted March 15, 2003 Report Share Posted March 15, 2003 Can u read from a CD drive as user ? What does ls /mnt/cdrom say ? Quote Link to comment Share on other sites More sharing options...
Guest ekp Posted March 15, 2003 Report Share Posted March 15, 2003 ls: /mnt/cdrom: Input/output error Quote Link to comment Share on other sites More sharing options...
Guest ndeb Posted March 15, 2003 Report Share Posted March 15, 2003 ls: /mnt/cdrom: Input/output errorI assume that is with a readable disc in the cd drive. Does cat /dev/scd0 give any output ? What do these commands say ? cat /proc/sys/dev/cdrom/info dmesg | grep hd dmesg | grep sr Quote Link to comment Share on other sites More sharing options...

Guest ndeb Posted March 16, 2003 Report Share Posted March 16, 2003 I would like to point out that ur /etc/fstab entry none /mnt/cdrom2 supermount dev=/dev/scd1,fs=auto,ro,--,iocharset=iso8859-1,codepage=850 0 0 is not consistent with ur /etc/lilo.conf entry append="devfs=mount hdc=ide-scsi" which does not enable scsi-emulation for /dev/hdb (so that /dev/scd1 is not created at all). So you will not be able to access your cd-rom drive at /dev/hdb. So u should change this entry in /etc/fstab to none /mnt/cdrom2 supermount dev=/dev/hdb,fs=auto,ro,--,iocharset=iso8859-1,codepage=850 0 0 and then run these commands as root: umount /mnt/cdrom2 mount /mnt/cdrom2 Then check if u can read a cd from ur cd-rom drive. Now, coming back to /dev/scd0 (the cd-r drive), does it work in MS windows ? Quote Link to comment Share on other sites More sharing options...
Guest ekp Posted March 16, 2003 Report Share Posted March 16, 2003 That did the trick for my CDROM. I can now access it. To be sure I understand what was going on here......was the problem the fact that my device was referred to by inconsistant names in the lilo config vs. fstab or was it incosistent mnt points? As far as my CDRW I have actually never used it in Windows as of yet. I loathe to use windows and only use it when it is impossible to not find an alternative. I will try. You have been a great help so far. Thank You Quote Link to comment Share on other sites More sharing options...

The lilo has nothing to do with the mount points of cd devices. My CDRW does work in MS Windows.U mean u can read cd from that drive in Windows, right ? Thats all I wanted to know. In linux, can u post whats in /etc/mtab ? Quote Link to comment Share on other sites More sharing options...
Guest ekp Posted March 16, 2003 Report Share Posted March 16, 2003 Yes my CDROM does work in Windows. Everything works in Windows. here is the /etc/mtab /dev/hda5 / ext3 rw 0 0 none /proc proc rw 0 0 none /proc/bus/usb usbdevfs rw 0 0 none /dev devfs rw 0 0 none /dev/pts devpts rw,mode=0620 0 0 /dev/hda8 /home ext3 rw 0 0 none /mnt/floppy supermount rw,sync,dev=/dev/fd0,fs=auto,--,iocharset=iso8859-1,codepage=850 0 0 none /mnt/cdrom supermount ro,dev=/dev/scd0,fs=auto,--,iocharset=iso8859-1,codepage=850 0 0 none /mnt/cdrom2 supermount ro,dev=/dev/hdb,fs=auto,--,iocharset=iso8859-1,codepage=850 0 0 /dev/hda1 /mnt/windows vfat rw,iocharset=iso8859-1,codepage=850 0 0 Quote Link to comment Share on other sites More sharing options...
Guest ekp Posted March 16, 2003 Report Share Posted March 16, 2003 I can read from both drives in Windows Quote Link to comment Share on other sites More sharing options...
Guest ndeb Posted March 16, 2003 Report Share Posted March 16, 2003 The entry from /etc/mtab none /mnt/cdrom supermount ro,dev=/dev/scd0,fs=auto,--,iocharset=iso8859-1,codepage=850 0 0 shows that /dev/scd0 is mounted. I suggest u do this in linux: try to read a cd from the cd-rom drive first. If that works, try to read the same cd from the cd-rw drive.

Guest ekp Posted March 17, 2003 Report Share Posted March 17, 2003 It appears that both will read. I was using a data CD in one and a music CD in the other. Should it have been able to read the audio CD? The tracks to appear when read through CDRoaster. The only thing wrong I do see at this point is that my CDROm is seen as CD2 and my CD R is seen as CD. I though the mount point that I created (CD2) was for the CD R. Quote Link to comment Share on other sites More sharing options...
