I hope you are capable of taking the HDD out. If so, all you need now is a sata to usb connector. Check out Amazon. Very inexpensive. You can even use the HDD as an external HDD and use it when needed.
If you grab one of those external HDD enclosures ($15), they come with a power supply. You just insert the hdd into the enclosure, plug up the power and usb. That's it. Now you can carry the hdd where ever you take the laptop.
