what is the difference between a REWRITABLE DVD 9 and the other disks?

Question

I try to burn movies that I copy to my laptop and it keeps telling me to insert a blank or rewritable DVD 9 disk any help

Answer 1

Your laptop is able to use DVD and RAM Disk (DVD 9).

Long story. But DVD 9 is RW RAM disk and then there is regular rw DVD disks, The single DVD RAM cost about $6-9 US. But just imagine another type of DVD. Once advantate is that they come with covers like the 3 1/2 disk. Then you do not need covers the the DVD

Ramdisks have the advantage of being much faster than hard drives and only require special software (and of course the computer's RAM). So in a way, you record on a DVD that is a RAM disk and in a way it is like a small removable hard drive, except you can record to it and it is faster than the hard drive for accessing to. But to expensive for me. I have a RAM drive too and plan to buy a two pack to see what all the fuss is.

So when you stick a blank DVD disk to burn it must be rw DVD. The rw is read/write. So you need the w to be able to write or burn a disk. Actually any DVD would work as you could only burn once on it. But maybe the format is different and it needs a disk to burn and reburn again. It might be a format it uses to burn disks. On regular r DVD, you can burn once. But maybe the program you use uses a format where it burns than needs to erase and reburn again. Also some movies are copy protected and you need special software to RIP them.
