How long to run a surface scan on a 500gb drive?

[hal]

Thanks for doing the math - I'm too lazy.

I'm using drive genius 1.5 - I think writing zeros might do the same, but it won't report found bad sectors. If the thing is loaded with bad sectors, I'll return it.

I just wanna make sure the drive is sound before I start loading stuff on it...

it just passed 100mil - no bad blocks so far...
