Fwd: Fwd: unable to mount cd

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello out there
 
I have trouble with ide-scsi on kernel 2.4.20-8
First of all there was not /dev/cdrom, so I changed /etc/modules.conf
added line
alias /dev/cdrom ide-scsi
 
Now I have a /dev/cdrom linked to /dev/scd0
 
 When I try to mount the cd I got the message:
 # mount -t iso9660 /dev/cdrom /mnt/cdrom
mount: block device /dev/cdrom is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
        or too many mounted file systems
        (aren't you trying to mount an extended partition,
        instead of some logical partition inside?)
 
The message I got from the kernel is:
 Sep 18 17:41:26 localhost kernel: Unable to identify CD-ROM format.
 Sep 18 17:51:06 localhost kernel: FAT: bogus logical sector size 0
 Sep 18 17:51:06 localhost kernel: VFS: Can't find a valid FAT filesystem
 on dev 0b:00.
Sep 18 17:51:22 localhost kernel: Unable to identify CD-ROM format.
 
GRUB is configured with hdc=ide-scsi
The inserted CD is the RH9 installation cd.
 
The output of cat /proc/scsi/scsi
 Attached devices:
 Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: {ONY     Model: CD-R  CzX810E   Rev: y.0a
  Type:   CD-ROM                           ANSI SCSI revision: 02
 
 looks very funny to me

 The output of cat /proc/ide/hdc/model
 SONY CD-RW/DVD-ROM CRX810E
 is correct.

cdrecord give me also a funny output

I have no problems on RH 7.3 with this device.
 
 Any idea ?
