Doing a 4X scan on a tesco +r right now. MID code is AML 002...? Disk may have been mishandled, as I cleaned the dust off on my t-shirt. I'll do at least a further scan on a seperate disk that went straight in the folder. Unfortunately, these were just the only disks I had to back-up to at the time when my Ritek were failing, and I used them only for reburning stuff that didn't fill the whole disk.
Problem was, when I first got the two spindles, they were coastering nearly every time. I upgraded my firmware from P to W, and I started getting credible burns! Ok, this was burned at 4X. Heres the quality scan coming up. (By the way, the -r UME01 media does NOT burn at 8X, but it seems to be almost perfect at 4X. I'm keeping an eye on the longevity... )
