This mini-guide assumes you have any version of Microsoft Windows and a DVD-ROM or DVD burner drive on your computer. This guide uses the archived version of
Nero Disc Speed 4. Other tools, including newer versions of the
Nero checking software, will be similar.
Discs may be "bad" for a few reasons. The most common ones are:
- The disc is fine. It's your player that's being uncooperative.
- The disc has a bad spot on it and is defective. Use this tool to check out the disc integrity.
Using Nero DiscSpeed
1. Insert your disc.
2. Start Nero CD-DVD Speed and go to the
SCAN DISC tab and then click
START.

It can take up to 10-15 minutes to perform a full scan of a full 4.38GB single-layer DVD-R, DVD+R, DVD-RW, DVD+RW, DVD-RAM or DVD-ROM. For dual-layer/double-layer DVD+R DL and DVD-R DL, it can take 20-30 minutes. Speed of scan largely depends on speed of your drive, as well as the scanning speed selected (8x or maximum).
3. Here's what a completed scan will look like.
