Hi,
.
I am having this problem myself and I think I read something about it either here or somewhere else, about someone that fixed his drive using knoppix + parted
.
Here is the diagnostics I could get from my drive, which seemed to be working fine last time I used it and it is not sounded weird or anything like that, so it does not apear to have a physical problem
