Question DVD & CDRW mounting problems

Hi there i have a problem mounting both of by drives first one
1. tosihiba dvd-rom
2. sony cd-rw

dmesg output :
hda: WDC WD400BB-00CFC0, ATA DISK drive
hdb: IC35L060AVER07-0, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
blk: queue c01899a4, I/O limit 4095Mb (mask 0xffffffff)
hda: 78165360 sectors (40021 MB) w/2048KiB Cache, CHS=4865/255/63, UDMA(100)
blk: queue c0189ae4, I/O limit 4095Mb (mask 0xffffffff)
hdb: 120103200 sectors (61493 MB) w/1916KiB Cache, CHS=7476/255/63, UDMA(100)
Partition check:
/dev/ide/host0/bus0/target0/lun0: p1 p2 < p5 p6 p7 >
/dev/ide/host0/bus0/target1/lun0: p1 p2 p3 p4 < p5 >

my lilo has the lines of append = "hdc=ide-scsi hdd=ide-scsi"

when i do:
mount /dev/ide/host0/bus0/target0/lun0/disc /mnt/dvd -t iso9660

I get :
mount: wrong fs type, bad option, bad superblock on /dev/ide/host0/bus0/target0/lun0/disc,
or too many mounted file systems

I need the two drives under scsi emulation so I can burn discs and copy cds with K3B.

cat /proc/scsi/scsi does:
Attached devices: none

Please tell me what am I doing wrong, or what's going on. Any help would be useful.

Using a Gentoo Linux on:
AMD Athlon k7 thunderbird, 512 ddr ram, 100gb of storage (40.0gb + 60.0gb disks, wd and ibm), sblive!, gefore2 mx,

thanx for any help

It appears that your drives are recognized. Have you tried to burn anything yet? Usually, to burn, you don't want a file system just needs the drive. The SCSI should be already emulated...check your boot-up log and see.

As far as mounting, does GENTO have a standard mount point for these devices? Look at your fstab file and see what it can set it to auto-mount so that if a file system is "seen" it will mount it at the mount point defined. Usually this would be /mnt/cdrom and /mnt/cdrom 1 (but I'm not sure with GENTO.

Or you can, if this is LISTED in fstab, just do a mnt command to the defined point in fstab. Better yet, PUT it in fstab with the file system you want....

Good luck

no nothing workx

i've tried the 'auto' instead of iso9660 and it still wouldn't mount
here is my fstab:

/dev/hdb1 /boot ext3 noauto,noatime 1 1
/dev/hdb2 / reiserfs noatime 0 0
/dev/hdb3 none swap sw 0 0
/dev/hda1 /mnt/winxp vfat users,rw,exec,uid=1000 0 0
/dev/hda5 /mnt/10gb_cvr auto noauto,users,rw,exec,uid=1000 0 0
/dev/hda7 /mnt/18gb_cvr vfat users,rw,exec,uid=1000 0 0
/dev/hdb5 /mnt/49gb_ibm vfat users,rw,exec,uid=1000 0 0
/dev/hdc /mnt/dvd iso9660 users,ro,exec,uid=1000 0 0
/dev/hdd /mnt/cdrw iso9660 users,ro,exec,uid=1000 0 0

still nothing...

any log files I've might've missed maybe?

You don't need the hdc=ide-scsi since your DVD drive is not a cd-burner. Also what does you /etc/fstab file look like? Do you have a unique entry for each of those drives? Something like:

/dev/cdrom /mnt/cdrom iso9660 noauto,user,ro 0 0
/dev/cdrw /mnt/cdrw iso9660 noauto,user,rw 0 0

I notice that your /dev/hdd /mnt/cdrw drive is set to read might want to change that to rw so that you can burn with it.

Here is a suggestion, but a long shot. But I have had these kinds of things before, but in Windows, of all things, not Linux. It all depends on the BIOS and how old it is. Would you be willing to swicth the Optical drives in your machine between master and slave? I know that it shouldn't make much difference which is which, but sometimes if the OTHER drive is the Master, and the old master was the slave, they are "seen" differently than before and work when they didn't before. You'll have to check your /etc/fstab file
again after that to see if it edited itself appropriatly, but that's not difficult.

It seems as if your system is not recognizing the CD-RW drive as an RW drive, only an ROM drive. That said, it might see things differently if you switch them...don't ask me why, but I've seen this before in my old test computer.

Aslo, check on updating your BIOS to the latest available for your machine...

I managed to get mine mounted by using the following
mount -t iso9660 /dev/sr0 /mnt/cdr
I also had to make a cdr directory in /mnt before mounting it.
Hope this helps.
