CDemu 0.8.0

Postby maman on Sat Aug 18, 2007 2:05 am

I tried sudo mount /dev/cdemu0 /media/vcd
and it says:

mount: block device /dev/cdemu0 is write-protected, mounting read-only
mount: you must specify the filesystem type

so I tried sudo mount -t iso9660 /dev/cdemu0 /media/vcd and it says:

mount: block device /dev/cdemu0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/cdemu0,
missing codepage or other error
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
In some cases useful info is found in syslog - try
dmesg | tail or so

Then I look up, but I can't find what filesystem an nrg file is. Can anybody help me?
TIA

nrg seems to be a Nero specific file similar to an ISO file

If the content is similar to an ISO it should be possible to mount as an ISO, but it is a generic Nero format

Search for a tool called nrg2iso ... It will convert Nero's proprietary *.nrg images to standard *.iso images. From there onwards it should be easy to use the files under Linux.

Okay, The *.nrg file is a data disc, so I suppose it could be done, and I got nrg2iso about an hour after writing the post. :wink:

But I'm still wondering, if cdemu can mount *.nrg and *.bin and *.cue to a "virtual CD drive", then how can I really mount it? what are their filesystems to be written on mount -t filesystem /path/to/cdemu /mount/point ? or do they have any?

Thanks for replying anyway! :D

If I remember right nero's .nrg file by default is iso9660 +joliet . But could be changed at the time of making the image.

Also isomaster in the software portal can convert nrg to iso.

Joliet is an extension of ISO9660:

*.nrg is a proprietary format and only few programs can read it. It is not a standard (ISO9660 is one!) :wink:

Hi, I'm back with resolution. I get nrg2iso, I use CDEmu, and I use mount and so it works (but also take more time to convert... *sigh*) but it's Okay.

So, this case shall be closed real soon :D
