Fedora Users — Re: /dev/cdrom is not a valid block device.

hi,

don't try to upgrade any old version to new one. this is my experience. just install FC2 as fresh.

if you will try it, your problem will solve.

Hi all,

I have upgraded from FC1 to FC2. Now I cannot access my CD-ROM drive.
When I type 'mount /mnt/cdrom', it says '/dev/cdrom is not a valid
block device.'

My investigations so far have included the following:

1. 'dmesg | awk /hdc/' produces:

ide_setup: hdc=ide-scsi
ide1: BM-DMA at 0xe008-0xe00f, BIOS settings: hdc:DMA, hdd:pio
hdc LITE-ON COMBO LTC-48161H, ATAPI CD/DVD-ROM drive

2. 'cat /etc/fstab | awk /cdrom/' produces:

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

3. 'cat /boot/grub/grub.conf | awk /hdc/' produces:

kernel /vmlinuz-2.6.5-1.358 ro root=LABEL=/ hdc=ide-scsi
kernel /vmlinuz-2.6.5-1.358smp ro root=LABEL=/ hdc=ide-scsi

4. 'ls -la /dev/cdrom' produces:

lrwxrwxrwx 1 root root 8 Aug 12 22:45 /dev/cdrom -> /dev/hdc

5. 'ls -la /dev/scd*' produces:

brw-rw---- 1 root disk 11, 0 Feb 24 08:02 /dev/scd0
brw-rw---- 1 root disk 11, 1 Feb 24 08:02 /dev/scd1
brw-rw---- 1 root disk 11, 2 Feb 24 08:02 /dev/scd2
brw-rw---- 1 root disk 11, 3 Feb 24 08:02 /dev/scd3
brw-rw---- 1 root disk 11, 4 Feb 24 08:02 /dev/scd4
brw-rw---- 1 root disk 11, 5 Feb 24 08:02 /dev/scd5
brw-rw---- 1 root disk 11, 6 Feb 24 08:02 /dev/scd6
brw-rw---- 1 root disk 11, 7 Feb 24 08:02 /dev/scd7

6. 'eject /dev/hdc' produces:

eject: unable to open '/dev/hdc'.

Same as when I try 'eject /dev/cdrom' or 'eject scd0'.

7. 'lsmod' produces (among other things):

scsi_mod 91344 2 sr_mod, sg
sr_mod 13348 0
sg 27552 0
uhci_hcd 23708 0
ehci_hcd 21896 0

8. 'modprobe ide-scsi' returns

FATAL: Module ide_scsi not found.'

Same as for 'modprobe ide-cdwriter'.

I have run out of things to try. Anyone else have any suggestions?

Thanks,

Geoff
