I hope this is the right thread.
I have two identical Sony DW-U18A drives, both currently flashed to the SOHW-832S CGB3 Firmware. I was perplexed that all my KProbe scans were coming out poor, when I realized that the other drive (in another computer) was giving me different, better results with the same discs.
After looking into it further, I determinded that my media was fine, and that one of the Sony drives is simply not scanning accurately. I determined this by scanning discs that were burned on my other drives (Sony DRU-510A and a NEC ND-2510A) on both 832s and comparing the results.
For instance, one disc got a PI Max of 12 and a PIF of 4 on the drive I believe is okay, and on the other the PI Max was 630. Thats a big difference. The drive in question reads discs okay, and it burns discs fine (scanning them on the good drive). Has anyone heard of one of these drives simply not scanning correctly? I am using KProbe 2.4.2 on both computers, with identical settings, and I get similar results using the Nero tool as well.
