What is a “Head Replacement”?

A head replacement involves physically opening your drive and replacing the delicate arms which read the surface of the disk.

This is a VERY difficult and precise operation which should not be attempted by anybody without experience.

Opening the drive can change the delicate balance and anlgiment of the internal components so even having a “quick look” can cause damage if the drive is repowered.

The drive head sits just above (think less than 1mm) the surface of the disk. If that head crashes into the platter your data is most likley gone.

As you can see from the photo to the right, there are many elements to a drive. This is a 3.5 inch HDD, Laptop drives and external hard drives are usually 2.5 inches so everything is a LOT smaller.
