Pros: this is the same model as the old one on my laptop

Cons: the old 80G hardrive on my laptop worked 3 years. crashed in the middle but survived until now except it starts to make noise. checkdisk show 4kb sector. so order this one to replace. I installed it right after it arrives. however, after installation, it makes noise too. checkdisk shows 8kb bad sector on this 160G. is this a prank? disappointing.

Overall Review: I don't know if we could find a way to avoid such dead on arrival situation.
