I am trying to read the data from CDROM drive but it showing the
message like device not found. I tried mounting the device in
/dev/cdrom. Please help me.
(2) Have you tried: mount -t iso9660 /dev/hda /mnt/cdrom
(2) I tried the option, same message "No medium Found "
(1) I tested this following way. I have two system with RedHatLinux 2.6
both of the system are showing same message for OK CD. Thats why it
seems that H/W problem is less chance.
What kind of CD is in the player? I mean, you tested the CD player with an audio CD in mplayer in this machine and it worked, now you have a data CD with a known filesystem (like a boot CD) and it doesn't mount in this machine but it mounts in another computer, correct?
You could try swapping the CD player with the one in the other machine to see if the problem stays with the machine or the drive.
From all above post I just want to note down some of the possible reason:
1) CDROM is damaged
2) CD itself is damaged
3) Filesystem of CD like iso9660, NTFS etc.
4) Underlying H/W problem like wire disconnection
5) mount process( improper command in shell)
6) May be something else
Test for all above are as following:
1) Try reading many number of CD of variuos format(like media, Data CDs)
in my case my CDROM is OK
2) CD is not damged, i troed it in some other comp it is OK.
3) Filesystem: I am not sure about the filesystem ( !I am very much clear in concept)
4) I think there is no Prolem
5) mount process is correct
Note: Actually I am worried about the dmesg, because this sort of error was not there in other OK system.
Which system are you using? Are you confident about the device naming on your machine? The hda name is usually associated with the first IDE drive - normally your main hard disk...
This could be that your kernel has problem with SATA drive. I know it sounds like nothing to do with your CDROM, but try booting your system with:
boot: linux all-generic-ide
This might force the kernel to "re-think" its understanding of the hardware...
