All About Hard Disk Filter Failure And Recovery

A hard disk is not totally sealed and vacuumed

. For hard disk to function properly, it requires suitable range of air pressures. Thus, they have a breather filter, integrated between inside and top cover of the hard drive. It equalizes the moisture and atmospheric pressure between the disk enclosure and external surroundings, while ensuring that no dust particle might enter inside. But if the disk air filter malfunctions, it could fail the hard disk. The general consequence is read/write head crash, which might seize the disk to operate or cause bad sectors. But you can still salvage your lost data, provided you have a suitable data backup or consult a professional Data Recovery Services.

Hard disk system depends on air pressures in order to support the read/write heads to float, provided by air filter. When the weather changes or disk is moved to a place of different altitude, the air filter allows to maintain the correct equilibrium. For reliable operation at above 10,000 feet altitude, the disk requires special manufacturing and sealing.

An air filter is basically a combination of holes covered with a breather filter that passes the air but not with the dirt or dust particles. Its malfunctioning can result:

Low Air Pressure: Due to low air pressure, the air will fail to exert force that is required for flying head to float at proper height. This can cause head to crash. To prevent this, some modern hard drives include special flying height sensors, which warn against low air pressures inside the enclosure.

Disk Contamination: When subjected to, if the disk air filter fails to catch dust particles, they can settle down on the platters. If the head(s) sweep over them, it usually causes head crash. This can develop bad sector(s) also.

High Moisture: Failed filter can cause excessive moisture to enter the drive. As a result, it can slowly cause heads to gain tendency to stick over the surface and hence, the disk to catch wear over the time. The spindle motor or head can get damaged.

Any of the above instances can render your hard drive unbootable and data inaccessible. However, all such cases of hard disk failure due to read/write head failure, spindle motor crash or wear issues can be safely tackled by Data Recovery NJ experts.
