:sad: As a direct result of purchasing 125 Ritek G04 and 25 Ritek G05 a couple of months back, I have been led to purchase a couple of batches of TYG02 to back-up the ones that are still even recognised. I bought Ritek printable 4X media from ukdvdr.co.uk (the companies customer support was not even worth dealing with. I now use SVP) in three wraps of 50. Â£19.47, free courier day. The last spindle of these was mixed exactly half with 8X G05 (hmmm...), and my benq 1620 with B7P9 f/w hated them.
That led me here, and all over the net. I upgraded to B7W9 and managed to get almost useable burns from the G05's! The G04...well, I thought they were the best media ever created. All my scans were mint; min 96-100% quality, averaging 2-12 PIF max. I scanned near every one, but was so confident in my media that I never saved the scans. If I thought I could trust ukdvdr to supply unmixed batches I'd have probably bought another couple hundred for sure! (So, thanks UKDVDR!)
The earlier burns aren't even recognised anymore in dvd player or burner as being media. Total coasters. As I'm working through them I'm seeing the PIF's improve gradualy. e.g: burns from four weeks ago tend to be around 30% quality and improving on a steep curve from there. If they were burnt within the last two weeks they still look like great media.
Why don't they degrade until they are actually burned? Many (not all) of them were never played after scaning and storing but same degradation. So far, thanks to Isobuster I've saved just over half the disks tried so far from my movies. There's loads of data disks to go through yet, and about another 20 movies to check.
Does anybody actually know what happens to these disks after they are burned to cause such catastrophy? I'm going back to backing-up now, just needed a break and hoped I could warn others about RITEK problems. I'm saving my disks and will be doing scans of the currently better ones for study in this thread later. Right at this instant though, I have to get on with saving what I can.
