Does the drive show up in Disk Utility??
But this thread seems a bit bizarre with the problems going on for over three weeks now and forty posts and it seems the drive still not working properly it seems.
Sounds like the drive died. It happens.
Small suggestion: When you have a new problem like this, it's better to start a new thread than to bury it at the end of a long thread, even if the topic is similar. "TL;DR" applies here.
EDIT: Ok, the board wants to convert T-L-;-D-R into an emoticon.
