"Note 1: Nero CD-DVD Speed has been renamed to Nero DiscSpeed"
It is latest version of this software - if there is somewhere else another program more recent, I do not know.
Because I would keep data for a big period of time, I would be also sure they remain readable as time passes, so I was searching something more sure than simple reading...
So, if DiscSpeed is not reliable, could you or someone else suggest another program for quality test?
And, because burning takes long time, it is possible test discs layer before burning?
