DVD+RW identified as DVD-ROM

Hi,

I'm experiencing a very annoying problem.

I tried to test my new DVD+/-RW writer writing some ISO images with
Blindwrite on DVD+RWs and I discovered later that the wrote medias
are not recognized anymore as re-writable medias but as DVD-ROM (Nero Info
tools).

So, now I'm unable to re-use this medias because the writing softs
identify the media as a DVD-ROM and refuse to erase or re-write them.

Someone known a method or a tool which permit to reset the media
identifier or force the erase of the media, without taking care of the
identifier, resetting the type at the same time ?

Note that the problem is not limited to the DVD+RW but I have also a CD-RW
with the same issue.

My writer is a Samsung SH-S203B and I can use any solution available on
Windows XP or Linux FC 6.

Any help is welcome.

Download burn4free and see if that behaves the same way.

I used CloneCD and it says that the disk is not "erasable". I also used
the little program Superblank but it failed also.

Finally, I solved the problem using the command "dvd+rw-format -force"
under Linux. This have erased the disk and re-initialized it.

Note that the root cause of the problem seems related to a strange
interaction, during the burning phase, with one of the "Virtual CD/DVD
readers" installed on my system (Alcohol 120% and Daemon Tools). After
having uninstalled both, I can burn the DVD+RW and the medias remains
recognizable as RW and not ROM.

Now I must find which soft causes the problem and if it's possible to
change this behaviour with the settings of the program.

Yes, the command blanks the DVD+RW but I'm unable to say if it does really
just a "blank" or also does a reformat.

According to the output of the command, I believe that the media isn't
reformated but just writed with empty data.

Hope that's help.
