like somebody else in this forum I got strong problems with two
It is always the same thing - they burn about 15 DVD’s (single layer) and 5
Dual Layer and then it comes burning dhe second (1) layer of a DL:
Error Power Calibration !
You can open and close the tray but the motor is not working (spindel) any more - device doesn’t become ready.
Finish and defective - returned them with Guarantee !!
Both were built in Mai 2010. Conclusion, they are not solidly built.
Must say I had them in an ext. enclosure (Power External SATA/IDE EN-525B) connected with USB2.
Was this the Problem - I dont know, but for shure I need one or two good DVD burners !
