[QUOTE=Goit;1926946]Yes, I meant optical burners.
So if I burn it and the scan shows good, then does it mean that it passed? Or can there be subtle differences such that it will deteriorate quicker than other discs, even though at the beginning it looks good?
Also, if I get a new burner, is the samsung one the best? Is it better than a plextor?
Also, does it matter weather if it is SATA or IDE?[/QUOTE]
OK. Scanning by itself doesn’t show much - a transfer rate test along with it is a good idea. Even then, initial scan quality doesn’t tell much about whether the disc will deteriorate (look at RITEK G05 - absolutely beautiful scans to start with, unreadable in as little as weeks).
Your best bet is to buy good manufacturers/brands, and store and handle them carefully, which I’m sure you already know. Other than that, you’d need a crystal ball 
As for new burners. There are plenty of new good ones about, have a read of some of the reviews in the Burners forum. I like Samsung personally, along with LG.
As long as your motherboard chipset has good SATA ODD support, you can pick whichever one suits your fancy.
Edit: As long as you use good media, there’s no reason IMO why you should pick CDs instead. My archival DVDs are standing up well (over two years now).
