Hi

I am trying to make a data DVD iso image and burn it from console.
I have made the image with mkisofs (genisoimage that is) like:

# mkisofs -r -J -o theimagefile.iso some_path

I have no problems mounting and using the image:

# mount -o loop theimagefile.iso /media/cdrom
# ls -l /media/cdrom

[all files are listed]

When I try to burn the image on DVD:
# growisofs -Z /dev/dvd=theimagefile.iso

everything ends well with no error.
However when I try to mount the DVD I get:

# mount /media/cdrom0/
mount: block device /dev/hda is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hda,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

So I follow the instructions:
# dmesg | tail
[122667.021890] hda: rw=0, want=7011976, limit=4
[122667.021908] attempt to access beyond end of device
[122667.021924] hda: rw=0, want=1252, limit=4
[122667.021942] attempt to access beyond end of device
[122667.021957] hda: rw=0, want=1028, limit=4
[122667.021973] UDF-fs: No partition found (1)
[122667.032490] attempt to access beyond end of device
[122667.032512] hda: rw=0, want=68, limit=4
[122667.032530] isofs_fill_super: bread failed, dev=hda, iso_blknum=16, block=16
[122667.065016] cdrom: This disc doesn't have any tracks I recognize!


I have tried several mkisofs and growisofs options but always ended the same.
I have tried to burn the image on DVD with K3D but nothing have changed (I guess it is the iso image that is not formated well)

Here is also the results from dvd+rw-mediainfo tool:
# dvd+rw-mediainfo /dev/dvd
[some hardware infos ...]
READ DISC INFORMATION:
Disc status: appendable
Number of Sessions: 1
State of Last Session: incomplete
"Next" Track: 1
Number of Tracks: 1
READ TRACK INFORMATION[#1]:
Track State: incomplete incremental
Track Start Address: 0*2KB
Next Writable Address: 2137040*2KB
Free Blocks: 160848*2KB
Track Size: 2297888*2KB
Last Recorded Address: 2137023*2KB
READ CAPACITY: 0*2048=0

Any idea why the track is incomplete ?
The image I am trying to burn is ~ 4GB in size and I am using regular 4.7 GB DVDs

Try:
growisofs -dvd-compat -Z /dev/cd0=imagefile.iso

Also post your /etc/fstab file entry for the cdrom drive.

You can try manually mounting the disk via
mount -t iso9660 /dev/hda /media/cdrom0

I have tried -dvd-compat already ... the main difference is that the session is closed.
However the disk can still not be read.

Here is my fstab entry:
/dev/hda /media/cdrom0 udf,iso9660 user,noauto 0 0

I have also tried to read the disk on Windows and Mac, but without success.

ok I have managed to create an ISO image burn it and mount the burned DVD smile.gif
To do this I have renamed the files using very short names (before there were some really long filenames).

But is there some option that could worn for long filenames ... or auto change the long filenames into shorter one ?
since some of the files could have descriptive names that could be huge (bigger then Joliet and Rock ridge formats)

Sorry, I am not aware of any other extension that would allow longer paths/filenames nor any auto name mangling feature.

ok 10x anyway ... on a second thought the filename length might not be a problem .... maybe the problem is that the filenames have spaces .... I will try replacing this
spaces with underscore ... if this goes well it will do the job since simple sed command will replace the spaces.
