I burned a CD using an iso image. The CD worked. It is mountable. It's files are there. Feeling paranoid, I tried to burn another CD with the same image and the same command. cdrecord didn't give me any complaints it hadn't given me before, but the CD didn't work. mount /dev/hdd produced /dev/hdd: Invalid argument mount: /dev/hdd: can't read superblock Some of my effort: [root@hobbes tmp]# cdrecord -dao dev=ATA:1,1,0 bin.iso Cdrecord-Clone 2.01-dvd (i686-pc-linux-gnu) Copyright (C) 1995-2004 Jörg Schilling Note: This version is an unofficial (modified) version with DVD support Note: and therefore may have bugs that are not present in the original.
