Problems are not yet over as there are a lot of laptops that use hard drives of the same dimension so again you need to find out the most appropriate hardware to go well with your laptop.
Once you finally get the correct hard drive for your laptop, you also need to check the type of connection which is compatible with the laptop. Mainly there are two types of connection – SATA and PATA are used to connect drives to the laptop.
