If you have never been on a thick carpet and felt a shock after touching a grounded object (or shot by a friend on purpose), you know the general effects of static electricity. But you know how it works, or as may be harmful to the components of the computer? Although there may be a bit 'stupid and meaningless, "static shock", or electrostatic discharge (ESD) can cause considerable damage to the hard drive. Comparable to a lightning strike damaged a tree to act can ESDlike a bomb exploded in units, in addition to blowing on the motherboard. But do not worry - if you have a few simple steps you can make sure they are well protected and in order to avoid a little thing, how to follow ESD big problems.
What is ESD?
ESD or "static shock" is part of an imbalanced high voltage field on a non-conductive surface of something - without saying that the disk, a screwdriver - just for a conductive surface in a rapid and uncontrolled postponed1.
"Static electricity" is the same part of an imbalanced high voltage field on a non-conductive surface of something, but has not yet reached the point of release of electrons is to reduce the imbalance between a conductor with a more positive charge because they are 2 to compensate. This imbalanced high voltage field is not "relief" until the conditions are right - until the number of electrons, the charge will decompress all of his position to build a point where the electrons can no longer bearose. When a conductive surface is a kind of "jump" at a distance, this experience is the process of approximation of the electric field 3
Unbalanced high voltage fields are everywhere, constantly flowing over and around us, and hear the people, because we are good conductors. The shock also sometimes when you touch a door handle is on the table after mixing in the same way as a lightning storm is 4
Some examples of tension:
3,000Volt - the average man feels no tension below this threshold.
8000 volts - yawning and stretching with wear.
15-20000 volt - pushing a plastic box above the carpet walk.
18,000 times - up by a cushion of foam on a nylon-covered couch.
35,000 times - walking through a carpet typically 5
What is ESD-Do?
While ESD will not kill you, you can certainly kill the computer components. Even if it takes a staticDischarge of 3000 volts for a shock, the feeling is much smaller fees, well below the threshold of human sensitivity, and often can damage semiconductor devices. Many of the components most sophisticated electronic systems can be used by taxes as low as 10 Volt 6 damaged.
ESD damage occurs when a charge is in the hand or a tool, a path of least resistance results from itself to a disc. When the energy of this weight is greater than the amount of energy being dissipated in the drive safely , damageMay 7 occur. Particularly sensitive to ESD are integrated circuits: processors, memory, chip cache and expansion cards 8 This damage can immediately dissolve something, the distribution of derivative or oxidation. Even more disturbing, you can not even the shock of electric traction, and it is - the impact of ESD are difficult to identify and often does not affect the unit until a few days to several months after the occurrence of ESD-9.
Recommendations for prevention
Fortunately, a few simple steps can help to prevent ESD damage and promote a long life for the unit.
Keep the unit in an ESD bag until you deal with it - a bag of ESD is designed to prevent static discharge.
Always wear an ESD wrist strap, an unpainted surface on the chassis of the computer-based.
If a bracelet is not available, touch an unpainted surface on the computer chassis before touching the disc.
Do not touch the connector pins on> Drive with the purposes of cabling or jumpers. Never use a bare finger or non-insulated tool.
Protect your journey from high voltage power sources such as fans and vacuum cleaners.
Do not ever groped for an electrical outlet or a data cable plug into a power supply unit, unless the field is completely off 10
Finally, adjust the temperature, you can also become a limitation of the ESD. Increasing the relative humidity of the room where the computer is located, you can significantly reduceDevelopment of ESD. Static builds up more easily in dry than in wet, this is why more often in winter than in summer in northern climates 11 get zapped.
So what happens if by some strange accident on the hard drive ESD experiences and your data lost? Do not panic, because the best solution is just a phone call. Kroll Ontrack has experience in dealing with being damaged by ESD and most modern hard disksTo meet the technology in the field of data recovery. Contacting Ontrack immediately after the discovery of ESD damage is the best option for you and your customers and continue to work productively.
ESD knowing that it exists, is the first step in prevention. With the following ESD handling procedures and understanding of the dynamics that are "static", you can ensure that the work was never a hard disk with a shattering experience.
