I just received a Samsung S182D as RMA for my LG4167 (I know, that's really strange, but I think that I'll never buy agaiin on that store ).

I can confirm too the lead-in problem. I can't take a picture, but the disc shows the same issue posted previously.

The drive came with the SB02 firmware, and i did a burn to see if also my drive is affected by this problem. And I'm not happy to see that this issue is also in my drive

The samsung sees the disc burned by itself as a blank media, but it run anyway the TRT, even if with a bizzarre graph. The liteon 1693 can scan this disc without problems, and the Sony/Optiarc 170 can read this disc without problems.

Pics are the following: burn, scan with liteon 1693, TRT with samsung, TRT with Sony 170.

Right now the drive is installed on an external box.
