Windows 8.1 unstable on 1tb hard drive
So my new Lenovo laptop crashed. It had windows 8 on a 1tb hd. The tech guy said the hd is ok but was unstable because windows does not perform well on a hd bigger than 500gb. He would like me to replace my internal with a 500gb drive and use my current drive as an external backup. Does this make any sense? It would run me an extra fifty bucks but I'm not sure about this theory.
