That's a new term for me but CD/DVD as a writable drive has always been iffy. You may encounter folk that never had it fail then one day it does. There is only only lesson from this and that's why we never reduce the copies of what we can't lose to just one or one place.
I have a DVD that was Flash-formatted and I used it to store pictures. It failed to work today but the properties showed that something was on the disc. I tried it on another machine and it still wouldn't open so I know it's not the computer. I even copied the disc and got the same results.
I've since put my pics on CD's which have never failed me but I'm at a loss to see why this DVD would fail.
