I just received a replacement 811s from an RMA to Liteon. They were very easy to deal with, and got the replacement drive back to me quickly (12 days elapsed, I shipped on the 16th and received the replacement on the 28th). Unfortunately, it appears they shipped me a bad drive. The drive came with HS0K, and I flashed it to HS0R before burning. I then proceeded to burn a RICOHJPNR01 at 8x. The burn went smoothly, but the Kprobe was terrible, the worst I have ever seen. Kprobe on my 1213@1633 yielded similar results. So I flashed it back to HS0K, and burnt another disk, only this time at 4x. Different results, but also bad. Kprobe started getting solid read errors towards the end of the disk, and I terminated the Kprobe test early after over 5,000 errrors. Here is the first Kprobe, HS0R with recommended tweaks, 8x burn on 811s.
EDIT: I just noticed the Kprobe was run at MAX speed on the 1633s. The results were very similar when Kprobe was run at 4x on the 811s. Has anyone else noticed that if you are running Large Fonts, you cannot see the box that allows you to set the speed in Kprobe 2.4.2?
