So I just got a new 20A1H. Seems I got a funky drive from my initial tests. I can't tell if it's a bad burner, scanner or both! Unfortunately I think I'll be taking this back to the store.
Here is a TYG03 disc burnt at 12x and scanned on a 165H6S.
Here is the same TYG03 disc from above, but this time scanned on my 20A1H... way different results (specifically PIF).
So to see which burner was out of whack, I scanned the same TYG03 disc on my old 832S and the results were pretty close to the results of the 165H6S scan. To me I'd trust the similar 165H6S and 832S scans rather than think the 20A1H is right and the other two drives are off base.
So, this initial testing makes me think my drive having scanning issues.
Okay, so I decide to try some burning then... well the results aren't pretty either. Check out the spikes at the start of the discs and the PIF totals!
TYG03 disc burnt with 20A1H at 16x
CMC MAG E01 disc burnt with 20A1H at 8x
Those aren't the only burns either, I tried a couple different types of media at different speeds and they all had those issues at the start of the disc. Anyway, not too happy with this drive that I got, I think it's got some factory defects. Unless anyone has any suggestions, I'll return it and probably get another one and keep my fingers crossed!
