Hi All ! After having read this entire subject, I still have a problem before proceeding with this fix .. I have everything ready (I hope) : the bricked Seagate, the T6 screw driver, one laptop with XP & HyperTerminal, another PC with power supply for the HDD; the business card, the CA-42 cable recognized by Windows (XP, 7 and vista) as USB/Serial adapter then “Prolific” driver was installed (was recognized as port COMX) and an audio card cable to link 3 wires of the CA42 to the HDD. My problem is the CA42 wiring … I know this was covered many times, but I have nothing like described in what I've read here (I’ve tried the “touching wires” sequence with HyperTerminal) but I still can’t figure out. I do not have 3 or 5 wires but 4 (red, green, black and white + shield around them) ! I then decided to open the USB end and see the labels on the IC for each wire… unfortunately there is no label (TX, RX etc …) My first question: according to the picture can someone tell me which wire is which? On the top picture, from top to bottom: red, green, black and white (unsoldered when I tried to open up the white plastic molding around the IC) and on the lower picture the shielding was soldered on this side but once again I messed up when removing the white plastic molding around the IC Second question (at this stage …) : although the white wire and the shield are disconnected, the cable is still recognized as the USB/serial by any version of Windows, does it mean that the 3 remaining connected wires are the right ones ? Do I need to re-solder the 2 connections (white + shield) ? Excuse me for my ignorance .... Many thanks in advance JP
