I just want to say, in case you are unfamiliar with this concept that 
speed disk(Norton) defragments.
You might have 20 gigs. But there may be no more than Half a gig 
actually free with no files inside .
So your 20 gigs could be small fragments bounded by other small 
fragments of data.
Your data itself may be split up in an unattractive way.
Speed disk moves around your files so that whatever free space you have 
appears as one big space.
This does make a difference when processing large files or using the 
automatic virtual memory,
both of which are happening when you copy a DVD.
I do this every two or three months on my boot drive.
I also have a main capture drive which is kept empty between jobs.
And a third drive to store video and DVD files for later. ( I also make 
this a second boot drive and start from it to defrag the main boot 
drive.)
