HDRC Online-Hard Disk Head Replacer

A head crash is a hard disk failure that occurs when the read-write head of a hard disk drive touches its rotating platter resulting in catastrophic damage to the magnetic media on the platter surface (see Hard disk platter.)The head normally rides on a thin film of moving air entrapped at the surface of the platter (some drives of the mid-1990s used a thin liquid layer instead)[citation needed]. The topmost layer of the platter is made of a Teflon-like material that acts like a lubricant. Underneath is a layer of sputtered carbon. These two layers protect the magnetic layer (data storage area) from most accidental touches of the read-write head.

A head crash can be initiated by a tiny particle of dirt or other detritus which can cause the head to bounce against the disk, destroying the thin magnetic coating on the disk. The disk read-and-write head is made using thin film techniques that include materials hard enough to scratch through the protective layers. A head crash may also occur when a hard disk equipped device is accidentally dropped. Modern hard disks incorporate free fall sensors to offer protection against this.

In your career you will come across hard drives that have been burned where the read write heads are almost burned out completely, flooded drives where the heads have suffered water or corrosive damage. Some hard drives will have suffered head damage due to the heads knocking against the limiters or if the hard drive has been dropped. In these and many other situations you will need to use head replacement technology.

The online physical data recovery course contains both text and videos to guide you as to how to perform a head stack transplant with ease.In time as your skills increase you can use the read write head tool to keep the heads from crashing during alignment. If you have a large quantity of these hard drive read write head tools you can choose to leave the plastic wedges in donor drives prior to using these parts if you wanted to prepare ahead.
