giver411, like zevia said... I would definitely try some other media before even considering RMA'ing the drive. All I burn is mainly TY, and I've gone thru a lot of it, and something I've learned is just because it's TY doesn't mean it's perfect media. I've had batches of TY02 with spikes at the end, TYG02 with a few spikes, etc... Don't get me wrong, TY is good stuff.:iagree:, it's just not perfect all the time.
You mentioned the scans looking different in Kprobe than they do in Plextools, and vice versa. Of all the media I've ever burned... TY02 +R is about the only media that I've seen that would look basically the same in Kprobe and Plextools.(and I wouldn't read anything into that) Like G@M3FR3@K said.. I'd take that with a grain of salt. Good luck.
