well the abuse is starting to go to Lite_on about the performance of this unit my customers are demanding full replacement from lite-on plus incurring charges to them for faulty backups which are not able to be read on other customer computers cd roms.
The problem seems to be in how it is actually burning to disc as the discs can sometimes be read then they just spit the dummy and lock cd rom up .
we have tried lots of media and burning programs and the fault is definitely these units cannot burn as well as a standard cd burner .
as for dvd they do not support the wide range of media as the pioneer 106d does
