No it won't be a program causing it. I wouldn't worry about it since it's only happened four times. But you can use HD Sentinel to keep an eye on it and see if it increases.Could it be a program that I used, messed something up? Can windows have errors causing HDD end to end error? I dunno if there's an issue with cable, it looks perfect... I took it out and put back in, (switch sides) same error.
What issue do you think it could be, if not a failing Drive ?
Its true, I never encounter any problems on the drive itself.
