I've buyed last week a Wytron dvd-399 controller:
DVD-399 controller Firmware 3.21 S/N : 39905C5102
Four (4) LG-4163B latest FIRMWARE A304 16x speed
No mixed brand nor model
Seagate Barracuda 7200.7 160 GB model: ST3160023A
DVD-R 8x RiData
Data Capacity in master:
Symptom of trouble:
All writers LED are flashing but the Controller LCD displays E0495+00. Understand that the buffer is 00. It stops reading from the master then the burn process fails. 495 MB It's about 10% of the job. Second try it goes to E1895+00 but never succeed.
The same thing happened in COPY mode C0324+00 and the same thing without harddrive, on the fly from 1 LG writer to 3 LG writers.
Writers are used 1 month.
Master is MOVIE DVD
Tested both On the fly and harddrive copy
