The latest important change is the addition of a new test: ScanDisc. Basically,
ScanDisc will show you the quality of a disc.
The test consists of two parts:
File Test which simply reads all files on the disc and reports all errors. This test
can also be used for benchmarking to give you an idea on how well the drive
performs with for example software installing.
Surface Scan checks the quality of each sector and shows the results in a graph.
3.4.2 Nero DriveSpeed
Nero DriveSpeed is an Ahead utility, which will set the reading speed of a CD-
ROM/DVD drive.
When you are running this utility for the first time, this window will appear. You can
detect all the support speeds of your burner by clicking on the “Detect” button and
the information will appear to the left.
You can remove certain supported speeds if you feel they are not needed by
clicking on the “Remove” button.
In addition, you can select the language of your choice by going to the Language
box and choosing your preferred language.
After your speed selection and language has been made, you can view the read
speed and spin down time of your burner.
