Again, sorry if you don't understand me but a have tried EVERYTHING, a have change everything, i will try to explain again:
1- I have the 3 pieces you tell me (all of it are NEW).
2- The floppy drive unit doesn't work as it have to.
3- I change the floppy drive unit for another, and the
same results, i change the floppy cable and the
same result, i change both things at the same time
and the same result
4- After this results I moved the floppy drive unit to
a older motherboard, in this case the floppy drive
unit works perfectly, with no error.
Then i want to know what is happening?? If i have tried everything, even i have tryiing cleaning the unit, but the same results!!! Do you understand me now??
