    I hope someone can help me with this, I know it's just something stupid so someone please just answer the simple question. When I'm putting DVD+Rs in my drive (NEC ND-2500A) to burn, Nero is detecting its capacity as being only 4.47 GB. But the disks I'm using are 4.7GB. Does anyone know why I can't get them to read as the right size?

    No discs as far as I am aware hold 4.7gb. The actual true space on the disc is I believe around 4.37gb which is perfectly normal. There is some formula for working out the true size on a disc compared to the advertised size but its a bit beyond me.

    The manufacturer's say they are 4.7GB, basiclly sayying 1mb = 1000kb, but in fact 1mb = 1024kb, so that is basically the difference from 4.7 to 4.3

    It's worth mentioning that this is the same incorrect math that's been used for hard drives for quite a while now. The first time I noticed it was for the original 100MB Zip disks which are actually 100,000,000 Bytes, but were called 100MB which is actually 104,857,600 Bytes. Due to their relatively small size, it wasn't that big a deal, but as media has gotten bigger and bigger the actual difference has become more and more noticeable.
