I stumbled on this thread by accident, felt I had to intervene
You get the message by now you should stay away from RitekG05. Even though I've never had a problem with the G05 series I have, the scare of their unpredictability panicked and made me copy my data onto safer, more secure RitekF1 discs. (All Maxell)
However, the experience I have had on G05 discs are only small - Just a ten pack of SumVision Gold Top I mistaked for Maxell I bought as new old stock from my local supplier. They burned okay, but they would burn only at 2.4x and no higher, but verified to about 10x (So higher than the max burning speed 8x). I've never had a disc dye do that before, so I was a bit concerned for it's longitivity.
No problem as of late, however The RiData, however, I have a feeling might have the edge over SumVision... But yes, if you have an G05 discs it's not worth finding out your data is unreadable in a few weeks because you burned to shoddy discs. If you haven't done so already, always back up to the RitekF1, or even better, Verbatim or Taiyo Yuden discs!
