Fedora Core 1 SCSI CD-ROM Won't Mount (always get "is not a valid block device")


Hello, all.

Today I installed Fedora Core from CD (2.4.22-1.2115.nptl is the version identifier that appears on my GRUB boot screen).

I have an Adaptec 29160 SCSI controller. There are three SCSI hard disks and a CD-ROM connected. The system is dual boot with Windows 2000, and all of the SCSI devices appear to work correctly on that OS. Also, Fedora found the controller, started up the aic78xx driver, and allowed me to install from CDs in the SCSI CD-ROM without any signs of trouble.

My problem is that I can never mount a CD-ROM when I boot into Fedora. The hardware seems OK since Windows is able to use it, and I've been able to confirm the following facts.

I see the symlink:

/dev/cdrom -> /dev/scd0

which is what I would think that I'd expect if a SCSI CD-ROM had been found.

In /etc/fstab I originally had what Fedora gave me by default, namely:

/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner, kudzu,ro 0 0

I've also tried:

/dev/scd0 /mnt/cdrom iso9660 defaults 0 0

and

/dev/cdrom /mnt/cdrom iso9660 defaults 0 0


If I do a 'cat /proc/scsi/scsi' I see my devices all listed:

Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: QUANTUM Model: ATLAS_V_36_WLS Rev: 0200
Type: Direct-Access ANSI SCSI revision: 03
Host: scsi0 Channel: 00 Id: 01 Lun: 00
Vendor: QUANTUM Model: ATLAS_V_9_WLS Rev: 0230
Type: Direct-Access ANSI SCSI revision: 03
Host: scsi0 Channel: 00 Id: 02 Lun: 00
Vendor: TOSHIBA Model: CD-ROM XM-6401TA Rev: 1009
Type: CD-ROM ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 04 Lun: 00
Vendor: QUANTUM Model: ATLAS_V_18_WLS Rev: 0230
Type: Direct-Access ANSI SCSI revision: 03

So all of the devices appear to be seen by the system, including the CD-ROM.

When I try to mount the CD-ROM however, I always get:

mount: /dev/scd0 is not a valid block device

The drive has a disc in it (in fact one of the CDs I just installed from, so it appears to be good), when this happens.

Does anybody have any idea what's wrong? This machine had previously had RH 8 and then RH 9 on it, and none of them ever had trouble with my drives, and it was able to naturally find them, allow them to be mounted and read, etc.

Any pointers would be greatly appreciated.

Thanks,
Jerry

The CD-ROM may not be on /dev/scd0. Try /dev/scd2.

Thanks for the pointer.

So I tried:

mount /dev/scd2 /mnt/cdrom -t iso9660

And got the usual:

mount: /dev/scd2 is not a valid block device

Any guesses on what I should try (or investigate) next?
