How do you remove harddrive sony NOTEBOOK vaio PCG-7505RX?

To remove the hard drive, flip the laptop over and remove all the screws from the bottom side. The plactic should lift off now. If it seems hard to take off, look for any more screws you might have missed. Once the back is off there is two more screws. One holding the USB ports and one at the top left of the hard drive. Drive should come out freely now. Hope this helps
