Glad to see the solved tick mark on this thread. While I do rightly take pride in what I had done on this thread, a major part, that of cleansing your PC of all malware, was carried out by mate cottonball, the Malware Buster.
I had no doubt whatsoever that once your PC was clean, your external hard disk can be fixed. I also knew that it could have easily been done on another clean PC but the need of the hour was cleansing your PC
and that is why I diverted you to the System Security sub-forum.
As Slartybart rightly said (" Soon enough FlippyLumpy will be an expert" ) in his post #35, you are one now
, thanks to SevenForums.
I also appreciate your perseverance and following the instructions to the dot throughout this thread.
Have a good night.
