Inside exposure: The environment that open quotation data restores asks
From;    Author:Stand originally
Deflection of attaint of chip of ageing of burned-out to magnetic head, magnetic head, magnetic head, magnetic head, dish group of a cut, magnetism is out of shape, the common hard disk breakdown such as electric machinery attaint, open quotation is the most feasible data restores a measure. At present almost all data restore to serve trader so-called the open quotation capacity that has major, after be being investigated deep however, can discover however, so called before open quotation is not so simple. If had visited hard disk firm, the factory environment that can exceed nobleness to be spent completely to its certainly is impressive. In fact, in hard disk interior, its are clean the 10 degree that degree has gotten international level, accord with human head ministry completely to drive the demand of skull operation. Ask so tall clean degree be not is captious, however of hard disk interior dish a concussion that cannot endure petty grain dust when high speed rotates.

Same argument, we cannot open hard disk case at will in air, make hard disk discards as useless extremely likely otherwise. The packing density of hard disk is higher and higher nowadays, especially after perpendicular magnetization technology applies, taller to the susceptibility of dust. In the course that resumes in open quotation data, if be simple only,hard disk is opened below common environment, so its danger sex cans be imagined. Even if is common 1000 class work station, clean degree also cannot achieve a requirement. According to flying guest data restores the experiment of ministry of central research and development to make clear: The hard disk that about 95% is control exposes 10 minutes of above to be able to discard as useless in air, the hard disk that about 40% is control exposes 15 minutes of above to be able to discard as useless in 1000 class work station. And if put work station in 1000 class to exceed clean form local 100 class environment, so the data that reveals time to be brought about in 30 minutes of less than loses scale controallable in 1% less than. And actually, at present voluminous data restores to serve trader is open quotation falls in common environment, dangerous level cans be imagined.

Breathtaking inside story of a plot: Poke magnetic head or change magnetic head to restore in data there is vocabulary of a cant inside the industry, be called ″ to dial magnetic head ″ . In fact, magnetic head blocks one of considerations that are circumstance of occurrence breakdown of partial hard disk really, about open quotation case from time to tome 5 % breakdown can solve a problem through this kind of method. However here should remind the user that has confronted data disaster: If your data is very important, so so called ″ dials magnetic head ″ will very dangerous, cause data extremely likely to be destroyed by 2. Real open quotation operation ought to change magnetic head, and be not simple ground to dial use magnetic head. Restore hardware engineer introduction according to data, really breakdown of partial hard disk moves magnetic head to be able to restore to succeed through dialing, but this is individual case merely. Normal service business is sure forbidden engineer uses major of this kind of blame and extremely irresponsible operation method. Well-known, magnetic head and dish piece between be not direct contact, and have very little space, magnetic head fixed position is very accordingly crucial. And optional ″ dials magnetic head ″ to cannot ensure for certain accuracy, risk factor is quite big!
