[QUOTE=albetan;2470811]In that case, generally speaking,
Is this result consider as a Good Burn ?[/QUOTE] Not really, there shouldn’t be any damaged sectors in a good burn (provided that the drive is working and scanning in a reliable way).
Or will this result increase the chance of the disc becoming unreadable after sometime?
That’s impossible to predict, but the disc won’t become more easily readable than it is right now.
I manage to copy the data back to my hdd without problem.
But it took 3hrs.
Is this normal considering it contain 30,000 small files?
Copying a lot of small files off an optical disc in non-sequential order can be a very slow process; you can estimate the time as at least the time it takes to read the whole disc sequentially plus the number of files (30,000) times the average access/seek time (let’s say 0.15 seconds) which is about 75 minutes plus the time to read the disc sequentially.
So 3 hours sounds a bit on the high side but it’s not out of the question, that this is what it would normally take on your drive.
When you want to extract an optical disc full of small files to your harddrive, it’s faster to use a program that reads the disc sequentially instead of in folder/file alphanumeric order; this avoids unnecessary seeks. You can use e.g. IsoBuster for such a sequential extraction.
