NEC 3520a & 1:1 Duplicator



Just upgraded my writer in my dupe to the above, but cannot write above 2x (4x sometimes works, but usually get source drive error)

I have upgraded to latast hacked firmwares possible, but still no joy

The reader drive in my dupe is a JLMS XJ-HD166S, and have used the latest hacked firmware availble on this site

Have tried the reader and writer on every combination of speed possible, but still get failures. They fail straight away (between 0% & 5%)

Any ideas?
