When re-using a rewritable DVD, I want to use the unused area of the disc.
So for example, when I burn a 1 GB Linux distro onto a rewritable DVD, and then burn other distro(s) onto the same DVD, it will use the same 1 GB area at the beginning of the DVD surface again and again. When the DVD no longer works, I will have used the 1 GB area at the start of the disc many times, and will have to 'throw away' the rest of the DVD, even though it is not used.
I am thinking that I could somehow modify the ISO, and add some dummy file at the beginning, which would never be read, and so the file possibly being bad / corrupted would not matter, since my actual files are on the fresh area of the DVD. Is this possible?
Is there a way around this ?
