Given the task definition and input, reply with output. Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.

My unit is toast and still under warranty but that means nothing because the replacement unit that I received from Buffalo was also defective. I lost data that I could not recover simply because the unit locked up on me. The company was completely unhelpful. The amount of time that was wasted on trying to fix this and deal with the Buffalo tech support is the worst part.
Negative Review
