I own the eZAU422 which is the iHAS422-08 drive inside an external USB enclosure. It came with 4L16 firmware, which I’m unable to find on the LiteOn websites as available for download.
I use only Taiyo Yuden +R (MID = YUDEN000 T02) or Verbatim +R (MID=MCC004) media. Since I just received this drive less than week ago, and since the quality scan thread is SOOOO LONG, I am asking for a suggestion of whether or not the Smart Burn, Hyper Tuning, Online Hyper Tuning, and Over Speed options should be on, off, or a mix of some on and some off for best quality. It seemed like I had read somewhere to turn off all these options except when using low quality media, or unknown media, yet some of the scans I saw seemed to have lower jitter numbers with these options all on (or maybe it was just the luck of the batch of media).
So far, I am running with only Smart Burn on, and all else off. Here is a sample of my results.
Are these burns good enough to warrant not fooling with other settings, or is there room for improvement?
Recommendations, including reasons/explanations why are requested, and I thank you all for taking time to respond.
