Keep Your Hard Drive Cool

The most common reason why hard drives fail is overheating. Overheating leads to hard drive failure and loss of data and is the reason why you need to keep your hard drive cool. Keeping the optimum temperature of under 75 F, and ensuring that the internal fan and temperature sensor are working, you can avert the disaster associated with hard drive failure.

The hard drive’s chamber has disks inside, also called platters which rotate on a spindle several thousand times a minute. The data is recorded as a set of magnetic pulses on the spinning platters. The platters are made with a magnetic coating on a ceramic base, which is heat sensitive. As the temperature continues to rise, the platters expand, and then contract as the temperature decreases. These changes result in platters that change in shape and size. The result may be a distorted magnetic surface and may have micro cracks and defects compromising the stored data. Also affected by high temperatures are the read/write heads which access the data from the spinning platters, the controller chip, and the head actuator of the hard disk. When the platter experiences physical damage by extreme temperatures, the magnetic media and heads will be affected. Since new hard drives store more data and their heads fly closer to platter small variation may lead to irretrievable data. Thus, most manufacturers are introducing new materials for disk platters made from aluminum and ceramic to glass and composite in order to avoid the damage temperature variations causes.

If a hard drive overheats, the data can be retrieved by contacting a professional rather than trying to retrieve the data at home. By attempting data retrieval at home, the data is put at further risk, causing further damage. Professionals will first analyze the damage, then using techniques and tools designed specifically for heat related data retrieval, they minimize any further damage to the hard drive. Most data recovery centers and experts advocate proactive procedures to eliminate data being compromised by overheating.

To avoid overheating, most new computers have built in cooling systems which cool the hard drive and its components directly. Using additional fans and improving ventilation and air flow around the computer can also keep the hard drive cool.
