That's great! I'm usually very unlucky when it comes to computer problems. As I said before, my laptop did not come with a CD for installing Windows 7; I only got the laptop, battery, power cord and paper, nothing else, so I will probably have to consult an expert for that (or buy it myself for about $100 ). And actually, ever since I put this hard drive in, every time the computer goes to sleep and wakes back up, a window pops up telling me that the Windows 7 activation key is invalid and I need to re-activate it. Today it told me to update it within 0 days if I want to keep using it. I wonder if that means it won't work tomorrow when I boot it back up, but there are other computers in the house I can use until I get this one all sorted out.
Oh yeah, if the activation prompts came up, the O/S is toast. You'll need to purchase a new full copy of Windows 7 64-bit and then load those free Sony drivers.
The only time I ever circumvented that function was on Windows XP, having installed it originally on an almost identical computer I built. When I moved one drive to another computer it continued to update. But I suspect the sensitivity of the activation process has tightened up considerably over the years. It used to allow no more than I think three hardware changes. Any more than that and the activation function would cease to work. But switching to a whole new (and physically different) computer....nada.
You can reinstall the O/S as many times as you want, but only as long as it's the same Windows Installation Disk on only that one specific computer. One thing for sure, I'd never buy a computer that didn't have separate restore or O/S and motherboard disks. Having such critically required software permanently on a hidden partition of the hard drive is nuts IMO. The obvious concern being what if the hard drive completely fails? Yet manufacturers do this anyways, no doubt to control costs.
