I have bought a 25 disc pack of Imation 8x DVD-R ages ago, it was MIL (Made in Luxembourg), Media ID was TTH01 (TDK 8x DVD-R).
1) LiteOn scan from April 14, 2010
2) Samsung scan from April 28, 2010 :eek:
3) LiteOn scan from April 28, 2010 :eek: :eek: (even though I scanned at 16x, 8x and 4x scans show a similar pattern)
4) LiteOn TRT from April 28, 2010 :eek: :eek: :eek: (Samsung also stops reading with L-EC UNCORRECTABLE ERROR just before the 0.5 gigs mark)
The disc was burned exactly a month ago with Plextor PX-716A at 8x and stored in a transparent 2-disc DVD videobox. Interestingly, I have stored a fake MCC 003 in the same videobox and it doesn't show signs of degradation.
As TDK has stopped producing blank media in Luxembourg anyway and 8x media is old-fashioned now, it might not be that interesting anymore. But if somebody has a lot of data stored on TDK 8x DVD-R, it might be worth a check whether the discs have been showing signs of degradation.
Actually just THIS is one of the main reasons why I prefer burning two sets of different media if there's something important to backup. :iagree: One can never rule out that discs might degrade, even discs from "reputable" brands, but it's unlikely that two different disc types exhibit the same problems.
