CDs not burning. These are 650MB recordable CDs, and I'm using Nero, and here are the messages I'm getting when I try to copy a CD: --------

i 12:27:52 Read CD done i 12:31:59 Start of speed measurement i 12:31:59 Speed measurement done: 20x (3063KB/s) i 12:31:59 Start of simulation at 4x (600KB/s)

x 12:35:10 Write error, loss of streaming x 12:35:10 Could not perform Write Audio x 12:35:10 >>>10:01:12<<< x 12:35:26 Simulation failed at 4x (600KB/s) -------

In this case the "i" is a little i in a circle, meaning, I assume, Information; the "x" is a warning-looking X in a circle.

After these, a dialog box comes up saying:

---- Simulation failed at 4x (600KB/s) ---

What am I doing wrong, please? My son says that I may need to defrag my hard drives . Could he be right?

Sorry if this is off topic - if anyone can help I'd be very grateful. I'm trying to make an interim copy of a CD. (Meanwhile I went to Rykodisk to order the same CD and got a "Warning: security certificate may not yet be cleared" type message; when I emailed them to ask to buy it I got no reply. Seems the gods don't want me to hear this singer.)
