Disk (dvd rw) is write protected

I used alchol 120% to burn a dvd rw and then after some time wanted to burn something else on it. but while formatting there is an error message saying " disk is write protected".

With windows 7 ultimate i was able to rightclick and format the disk ....

again i burn the same disk with my laptop having windows 7 home premium. IT IS AGAIN GIVING THE SAME ERROR.

i have tried other softwares to erase or format that disk but it failed.

i also read other posts regarding this matter on number of forums but no satisfactory answer.

is there a security issue with alcohol 120% or is it windows 7 home

Thanks

Try uninstalling Alcohol, then burn with Imgburn or CDburnerXP (both are freeware, download them).

Thanks for the reply.
I think the problem is the way i burnt the image
the dvd drive is showing the media type as DVD ROM
not a dvd rw.
Thanks again
