When ever I try try to mount any burned CD/DVD media I get the error below. mount_cd9660 -v /dev/cd0 /mnt using starting sector 0 mount_cd9660: /dev/cd0: Input/output error Exit 1 Which in dmesg results in... g_vfs_done():cd0[READ(offset=-2207623839744, length=2048)]error = 5 This is odd because if I unplug the USB CD drive and plug it into my netbook running a old RELENG 7.0-STABLE it works. On the machine that it errors on it has been doing this for any burned CD/DVD media in either the DVD drive in it or on the USB one I've been testing with. I know the disk is good as I can mount it on other machines I've tested it on with the same drive and different drives. Any one have any ideas? -------------- next part -------------- A non-text attachment was scrubbed...
