Ah, I hadn't understood it that way. I can see possibly being able
to verify an ISO, but not a data DVD/CD after the fact in general.
Many people (me included) will drag folders from several places
onto the Nero "structure" to burn, so after the fact, nothing would
know where to look for the various folder sources. If you are
just copying a tree of some sort, check out something like
BeyondCompare (not free, but very good), but for when the
chunks come from various locations, I don't know how you
would do it.
On the other hand, you may not need to verify the files as
much as scan the disk for read errors. CDSpeed, DVDInfoPro
and others will do that for you. If it shows no errors, you should
be fine since a bad sector should give a CRC error. Of course
if the data being fed to the burner was bad, then the sector could
read fine, but still have the wrong data although I expect that is
not very common.
