HARD DRIVE FAILURE

Bring in your computer to our chandler,Gilbert or Mesa locations and We will recover the data out it fast! The hard drive is the single most important device behind the mass acceptance of personal computers in the home and workplace. The ability to save significant amounts of data within a computer itself, rather than being forced to place it on external media finally fulfilled the potential that the PC had never quite lived up to, at least as a business tool. Hard disk storage ability has increased massively since the early days of the technology, and will likely continue to increase in the future as drive's cost per megabyte of storage drops equally fast.

Unfortunately, the underlying technology of hard drives has changed little in the years since their invention, meaning that their essential weakness still exists. The simple fact is that hard disks are mechanical devices with moving parts, and as such, will fail eventually and inevitably.

Why Do Hard Drives Fail?
A hard disk drive is composed of one or more platters, spinning disks containing tracks of magnetic information. These platters are read by read/write heads that hover just above the surface of the disk on a cushion of air created by the speed of the platter's rotation. These heads are attached to an armature that can move them over the surface of the disk, powered by a magnetic 'voice coil'.

The whole assembly moves incredibly quickly and precisely. The platters generally rotate at either 5400 or 7200 RPM, and the movement of the read/write heads to separate areas of the disk is almost instantaneous.

Most computer components, of course, are completely electronic with no moving parts. As such, they have an indefinite lifespan. They do fail, but they don't wear out. Something has to cause them to fail, like a power surge or the like.

Hard disks will fail eventually because they are mechanical devices, and as such, wear out. It's as simple as that. The most likely reason for a drive to fail before its time, however, is physical damage.
