I installed Ahead's InCD on my machine, and since I owned a DVD recorder I decided to try formatting a DVD-RW disc, since I use the recorder almost exclusively for data storage. I let it format while I was out for a couple of hours (I knew it had to basically write to the disc first, which took 59 minutes, then do some sort of verification, which probably took just as long) and in the end I had a formatted disc.
What I noticed first of all was that it had a lot more data capacity than I had originally anticipated, about 4,701 million bytes. A formatted CD-RW goes from about 656MB to about 533MB.
Reading and writing to the disc seem to go just fine, except my DVD-ROM can't seem to read the data from the formatted disc (it's a Lite-On 16x 166S).
My question is now, why do DVD-RWs lose so little data percentagewise compared to CD-RWs while formatted? (656MB to 533MB compared to 4,709 million bytes to 4,701 million bytes)
