re: how do I mount my cdrom-which is a cdrw
Hello All:
What is the filesystem for /dev/scd0? It's for a cdrw: I'd like to mount it and then automount it so I don't have to go through this again. Thanks, ergo_sum |
filesystem is iso9660
mount /dev/scd0 -t iso9660 /mnt/wherever If you add an entry for the drive in you /etc/fstab then you won't need to type it out every time. simply mount /mnt/wherever see man fstab |
Here is my fstab:
I seem to have a conflict somewhere, because my cdrw is either sc0 or cdrom. It's a cdrw, so I think it should be scd0. 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/hda3 swap swap defaults 0 0 /dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0 /dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0 Anxiously awaiting your reply. ergo_sum |
Well, usually /dev/cdrm is just a soft link to another device, like /dev/hdc or something like that.
If you use SCSI emulation for an IDE CD-Rom drive (hdc=ide-scsi might show up in your lilo.conf) then it might show up as another device. I think on my system the CD-RW is designated as /dev/sr0, but I just re-directed the cdrom link ln -s /dev/sr0 /dev/cdrom |
So what do I do?
|
Well, we need to determine what device designation your CD-Rom is assigned to. (I'll show info from my systyem as an example)
look in your /etc/lilo.conf for something like this: Code:
append="hdc=ide-scsi" If that's the case, then look at the output of cat /proc/scsi/scsi mine looks like this: Code:
Attached devices: ln -s /dev/sr0 /dev/cdrom Then I updated my fstab entry: Code:
/dev/cdrom /mnt/cdrw iso9660 noauto,user 0 0 |
Yes.
Here is the relevant part in my /etc/grub.conf: hdc=ide-scsi And here is /proc/scsi/scsi: Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: LG Model: CD-RW CED-8080B Rev: 1.04 Type: CD-ROM ANSI SCSI revision: 02 The most important part of your post is that your cdrw is /dev/sr0. I need to figure out what my cdrw is. I don't have a listing of /dev/sr0. So I guess my question is how do I figure out what my cdrw is? Looking forward to your reply. ergo_sum |
I'll have to track down where it told me that. Just out of curiousity, dod you try mounting /dev/sr0?
more later..... we're getting close. ;) |
What distro / version are you running?
Have you tried mounting a data cd to /dev/scd0? What are the output messages of dmesg for your CDRW? |
Running rh 7.3, kde desktop.
Didn't try mounting sr0 because there's no such device in /dev/ I'm a newbie, so does that matter or not? ergo_sum |
Here is dmesg | grep 'hd'
ide_setup: hdc=ide-scsi ide0: BM-DMA at 0xffa0-0xffa7, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xffa8-0xffaf, BIOS settings: hdc:DMA, hdd:pio hda: WDC WD400EB-00CPF0, ATA DISK drive hdc: LG CD-RW CED-8080B, ATAPI CD/DVD-ROM drive hda: 78165360 sectors (40021 MB) w/2048KiB Cache, CHS=4865/255/63, UDMA(100) hda: hda1 hda2 hda3 hdc: DMA disabled This is all good, except for the DMA disabled part. Could that have something to do w/ my cdrw not working/ gone missing? |
