Hard drive can be replaces with no problem however it make take a little time and concentration. These days many laptop computers are designed so the hard drive can be quickly and easily removed by the owner. Unfortunately, it’s not as easy to replace a hard drive on many desktop computers. But even though you need to open up the computer tower to access the hard drive, it can still be accomplished without the help of a service technician.
Remove the screws from the panel and slide it off of the tower to expose the internal components of the computer. The rectangular hard drive will be visible at the front of the computer tower and there will be two cables connected at the back of it.
