Software for testing DVD drive and DVD disc?
 

What is the best free software to test my DVD drive, optical media and DVD disc burning? I wonder if all of them are 100% good

You mean check ..... burning quality ?

not all burners can be used.

Best of all were the old BenQ-1640 + 1655

I have the latest version of Nero CD / DVD Speed but I'm not sure if he check drive

Come to the burner depends.
Most burner are not suitable.
What version of Nero?

i use imgburn for burn disc

and Nero DiscSpeed

Use Nero Infotool 4.
But you need a specific burner to run some of the more advanced quality tests (PIF/PEI/PO/jitter).

I want to test if there is any error and problem in my dvd drive, virgin optical disc and burn DVD disc, best free software

This is also equipped with the latest Nero Info Tool
[Nero but I have not installed to burn]

Only some burners are suitable for reading in terms of quality.
You have to try

Here is an example ........ DVD from 2008 TY course.

Total I have 15 burners [to try CD / DVD / HD-DVD and BR]
Unfortunately, a DVD burning clean is an art.

I should download the Nero InfoTool? it is full and free?

It's freeware. It use it all the time.
Nero DiscSpeed works fine, too.
I forget which is being used on my main BenQ scanner, as I'm not there right now.

1 Which is better, Nero DiscSpeed or Nero InfoTool?

2 Nero 11 InfoTool is good?

You just need to try them and see for yourself. At some point, posting questions if not as useful as trying it out.

I want a software to save on the PC, not a lot of software, but I want the best
