Mounting a DVD - "unknown device"

[LordMatt]

I can not get this DVD to mount for love nor money. It works fine in the crappy Windows POC I just pulled it from to replace a DVD that was doing a similar thing. I'm guessing the last update sent something wonky (again) but I don't know how to fix it.

#:/dev$ sudo mount /dev/scd0 /media/cdrom1
mount: /dev/sr0: unknown device
#:/dev$ dmesg | grep dvd
[    6.485877] sr0: scsi3-mmc drive: 48x/48x writer dvd-ram cd/rw xa/form2 cdda tray

fstab

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0

/dev/scd1       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0
/dev/scd0       /media/cdrom1   auto          user,noauto,exec,utf8 0       0
#/dev/scd0       /media/dvd0   udf,iso9660 user,noauto,exec,utf8 0       0

The above is stuff that other threads all over the internet seem to ask for with mount related problems but most of it is semi-gibberish to me.

I've learned tonight what a mount point is, how to make one, what the columns in fstab is, how to (sort of) use the mount command in the CLI, that I might want to look in dmesg for stuff using grep, that google sometimes has more noise than signal and that I don't want to fix computers for a living.

Errors like mount: no medium found on /dev/sr0 are fairly common too BTW. I'm going spare and spent what should have been a chilled out night of DVD watching getting stressed and digging about in the guts PCs. Had I known it was a hardware problem I would not have bothered changing drives over.

There is a disk in the drive and the errors are the same if that is a CD or a DVD.

A whole night wasted and no answers.



Please help.
