[quote="fzabkar"]My jumper runs from the +5V supply (ie the drain of Q1) to the bases of Q3 and Q6 via the SATA control pin.
possibly one out of these R1,R2,R5 could be bad . i did not check your diagram before . i was assuming SATA logic pin direct to Q1 ( G ) and that was not even gate . that is drain lol . i never seen this device and i assumed only .
mr Fzabkar i have a question in my mind and would like to ask you ... do you have same device right now with you? i mean its not possible for anyone to draw diagram and check connections of components on base of only pic . at least for me its not possible . please can you share what is magic or you have it in your hand ?
