While I can’t speak for anyone else, I’ve had nothing but trouble when trying to use re-write CDs & DVDs. So, while we, at my site, have a few drives capable of re-writing, I never use the option and if anyone asks about it I tell them to stay away from it. Not worth the hasssle with tempermental machines.
I’d buy one and test it to see how it works. Then, if it works to your satisfaction, purchase the bulk of the PCs and their optical drives.
Hope this helps.
