How do I rewrite discs???

[RetroDude83]

I was wondering how I can rewirte DVD+R media and CD-RWs once they were burnt already. My new burner seems to be able to do it but I can't find that option in Nero...? I have a couple of dvds which I got from friends and I don't need them anymore and now wanted to re-write them. does it make sence to rewrite discs or is it just a shitty additional function no-one uses???

You can only rewrite media with a -RW or +RW (rewriteable) suffix.

CD-R, DVD-R and DVD+R are can only be written to on one occasion, though you can add a further session to a CD-R if it was not closed when written. Audio CD-Rs must be closed in order to be readable by CD players so if the discs in question are audio then even that avenue is closed.

In Nero Express at the file add in window click the "more" tab, you'll get a drop down that has the erase disc option. as stated RW media only
