/dev/cdrom is not a valid block device.

[malik malik]

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
