The video below from HDDSurgery is an example of a repair or diagnostic procedure where a hard drive with damaged heads might have the heads replaced by purchasing another new identical drive and pulling the heads from that drive to replace the defective ones.

While this video makes the procedure look quick and easy, it’s actually a very detailed and delicate process that must be performed meticulously in a costly cleanroom environment. If dust particles, clothing fiber, or hair were to get into the drive, that would likely result in further damage to the drive later. For this reason a specialized and costly clean room must be used.


Below is a screenshot image from the above video showing the internal components of the hard drive.

The graphic above shows the variety of causes for lost data and the general costs for recovery. [Click image above to enlarge]

The prices shown are based on an estimate of $70 – $90 per hour, and going clockwise, the estimated time required for recovery increases.

When drives have a mechanical or circuit board failure, then additional equipment and time is required to perform the recovery. The extend of drive damage will determine the cost of recovery.

These are estimates only. The actual cost may be above or below these estimates.

About 10% of the drives submitted to us have severe mechanical damage, and those get shipped to our cleanroom partner group.
