 |
|
I just installed Blag 19999.00081 and I like it a lot. The one problem is that if I try to mount anything in my DVD-ROM drive, I get the error :
mount: No medium found
This happens whether I'm logged in as root or as a user (cbw). When I put an audio CD into the drive, CD Player reports that the drive is open. In each case, when I put a disk into the drive, the LED comes on and the disk spins and then nothing. I also have a CD writer which seems to be working fine and can mount/read all the disks I've tried.
The hardware browser correctly identifies the two drives :
JLMS XJ-HD166S Device /dev/hdc
SONY CD-RW CRX255E Device /dev/hdd
cat /etc/fstab

I tried changing the ownership of /dev/hdc to root.disk and changing the permissions, but it didn't make any difference. Rebooting the machine resets the ownership/permissions, I'm not sure where this happens.
It occurs to me that this might be a hardware problem, which is just coincident on my installing Blag, but I'm hoping I've missed something.
Sorry for the long posting, but I wanted to give as much detail as possible. Any help would be appreciated.

Try:
| Code: | mount /dev/hdc /mnt/cdrom
mount /dev/hdd /mnt/cdrom |
Also, is it a regular data CD? You can't mount audio CDs like a data disk.
Also, to make sure the drive mapping is right, try:
| Code: | eject /dev/cdrom
eject /dev/cdrom1 |

I'm sorry, I didn't make myself clear
/dev/hdc is the DVD drive.
/dev/hdd is the CD writer.
If I put a data CD into the DVD drive
| Code: | mount /dev/hdc /mnt/cdrom
mount: No medium found |
which is my problem
| Code: | mount /dev/hdd /mnt/cdrom
mount: No medium found |
which is not surprising as there isn't anything in the drive.
If I put a data CD into the CD writer
| Code: | | mount /dev/hdd /mnt/cdrom |
mounts successfully

I didn't try to mount an audio CD. I was saying that I can neither mount a data CD nor play an audio CD. I can play an audio CD in the CD writer (although it's not connected to the sound card).
opens the DVD drive.
opens the CD writer. So the mapping is as expected

Long posts with good info == good++ :)
It looks like you've done everything correctly. I'm not sure what to say... hmm....
Perhaps add "-t iso9600" to mount command, but I don't think this will solve it either. Perhaps try a variety of CDs just to see if it's just a particular burned one that's failing.
Sry I don't have a better answer, but I don't see that anything is mis-configured.
