I have seen SSD death many times and it is a strange sight indeed. What is interesting about it when compared to normal drives is that when normal drives fail it is - mostly - and all or nothing ordeal. A bad spot on a drive is a bad spot on a drive. With SSDs you can have a bad spot one place, reboot, and you get a bad spot in another place. Windows loaded on an SSD will exhibit all kinds of bizarre behaviour. Sometimes it will hang, sometimes it will blue-screen, sometimes it will boot normally until it tries to read or write to that random bad spot. Rebooting is like rolling the dice to see what it will do next - that is, until it fails completely.
