I have a Pionneer 212BK and its connected to my laptop using a USB2 to SATA interface.
I have a SH-203B that I also use using the adapter.
I have tried burning 2 single layer dvds at 8x using the Pionneer, the first was a MCC 004 and the second a MCC 03RG20. The burn quality at 8x on the MCC 004 had pif spikes of around 500 when scanned with the SH-203B and the MCC 03RG20 was that bad that it wont read in my SH-203B or my Xbox 360.
Weirdly though I burnt a dual layer disc at 2.4x earlier on some really cheap dual layers and the burn quality was around 85.
I bought the pionneer just basically so I had backup drive so I could use one for one type of media and one for another.
Do I have a defective unit or is there a weird problem with running this on a USB2 interface.
I am only asking because I will get my money back if there are known issues.
Thank you for you help.
