During the normal operation of a hard drive the delicate read/write heads float over the rotating media. The arm that holds these heads is shaped almost like an aircraft wing to provide this lift. This novel approach reduces the overall mass of the delicate assembly allowing higher transfer speeds but also because there isn’t contact between the two components then the life span of the hard drive is greatly improved.
The media used in modern hard drives is a Cobalt Alloy which is very soft so is protected by a thin layer only microns in depth of a lubricant that acts as a buffer if the heads ever were forced onto the media due to misuse of the hard drive.
This condition is referred to as a head crash, and the media will survive a number of these during its normal working life. However if this crash is severe enough that a scratch is created then the debris will be picked up by the heads and dragged around causing more damage and so the condition can quickly escalate into a huge problem.
It is important that when a hard drive has been abused and the data contained is very important that the hard drive isn’t powered.
The constant power cycling in desperate attempts to access this data can reduce the chances of a successful recovery and in extreme case render the hard drive beyond repair.

The hard drive failed on my MacBook Pro. Applestore advised they couldn’t recover the data when they fixed the laptop, and that the data would be lost (including my photos that had not been backed up). I described the issue with R3 by phone, and they were confident they could recover the data and confirmed the cost. It took just 16 hours from registering with R3 that I wanted them to look at the failed drive, to being notified what data had been recovered. I was kept informed of progress throughout, and all my files were recovered.
