I primarily use write-once disks; therefore, I don't use too many DVD+RWs or CD-RWs so my experience with re-writable disks is limited. I was wondering why a re-writable disk goes bad after a certain number of burns. I have heard that DVD+RWs, DVD-RWs, and CD-Rs can last up to 1000 burns while DVD-RAM can last up to 100,000 burns. That gets me to wonder what makes a DVD-RAM disk better and what makes the others worse.
Why does a re-writable disk go bad? And - once they are bad is there any way to restore them, or are they permanently trash?
