    Cloned my old HD, installed this one, thermal pasted (recommended, if you swap out the memory from a Surface Pro, for example you'll find a metal casing with thermal tape underneath.) Thought all was good, and then Windows BSOD (Blue screen of death) Upon doing a little research, found you'll need to update the drivers, especially for Windows. Once that was done, no problems. Just wish I had known and not wasted so many frustrating weeks figuring it out.
