My first scan (Mitsubishi 4x RW)

I wonder what these funny graphs mean. The sudden jumps near the end, I mean. If it was a bad write, the speed should drop, shouldnt it?
The last scan is with Nero CD/DVD-speed.

You can get these kind of graphs if you’re testing a DVD+RW which has not been fully formatted.
Nero CD-DVD Speed will test the full capacity of the disc even though there is only 3.4 GB data on it.
However, this has been fixed in version 3.20.

I hope this helps.
