40125s can not read anything burnt by itself

Hi, i’ve been having this problem since the first time i updated the fireware, now i just flashed it with the latest ZS0N fw, it still can’t read any cd-r’s that it has just burnt. i’ve tried nero, fireburner, clonecd with different brands of medias at various speeds, but none worked. btw, my dvd readers both on my pc and the laptop can read those disks with no problem. Anyone else has the same problem? please help.:confused:

forgot to mention, the burner has no problem with retail music cds and other non writeable disks.

i’ve had this problem under xp and my previous PC,
switch pio to dma mode has resolved the problem for me.
