Problemet:

Larry harry # mount /mnt/cdrom/
mount: No medium found
Larry harry # mount /dev/cdrom /mnt/cdrom
mount: No medium found
Larry harry # mount /dev/cdrw /mnt/cdrom
mount: No medium found

Litt informasjon:

Er ikke 100% idiot:

• Kjører kommandoene som 'root'.
  
• CD platen funker på andre maskiner.
  
• CDrom'en funker, kan boote fra livecd.
  
• Har prøvd mount -t iso9660 -o ro /dev/cdrom /mnt/cdrom og alle lignende ting.
  
• /mnt/cdrom, /dev/cdrom og /dev/hdc eksisterer.

Har du sjekka at /dev/cdrom faktisk er linka til /dev/hdc?

Har du prøvd å mounte /dev/hdc direkte?

Sjekket og testet.
