Hi, i am really confused i've read this post and also this post i then purchased this converter http://www.ebay.co.uk/itm/260836151037?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 and this cable http://www.ebay.co.uk/itm/250653067355?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 ny steps: 1. connected the cable with the converter 2. performed the loopback test succesfully 3. connected the tx(hdd) to rx(converter), rx(hdd) to tx(converter), gnd(hdd) to gnd(converter), sata power supply from same pc and added the card on the motor 4. waited for the motor to stop 5. started hyperterminal or putty (under w7) 6. entered the correct values COM3, 38400, 8, 1, N, N and connectd 7. when i type Ctrl + z there is no response 8. reversed the rx and tx but i get the error with the weird characters 9. reversed again but no response 10. removed gnd no response 11. removed convertor's power supply got the error with the weird characters (weird error) (my setup) any ideas apreciated
