hello
I am maintaining a system with rhel4. I used to take backup of DATA in DVD-R through K3b application.
Today I observed that blank DVD-r not mounting automatically. I tried 3/4 Blank DVD-R but no result. However already backed up DVD through K3B automatically mounted as K3B DATA PROJECT and data can be read.

I tried to mount blank DVD by the command:
# mount /dev/cdrecorder
I observed that the DVD Driver (ATAPI DVD A DH16AYH ) LED indication is on for a long time and than stop.
the output is : /dev/hda : input/output error.
mount: block device /dev/hda is write protected mountng read only.
/dev/hda: input/output error.
mount: /dev/hda : can't read superblock.

I tried to mount through kinfocenter that is /dev/hda /media/cdrecorder

It returns : No medium.

For blank cd it is not a problem. It automatically mounted and backup is no problem through K3B .

I am suspecting some software problem.
Please help me to sort out this problem.
