The breakdown service of the hard disk is a stage
impossible to circumvent to recover the files following a physical,
mechanical or electronic breakdown.
In addition, a simple electronic problem of hard
disk often involves a mechanical breakdown. A complete diagnosis
in clean room makes it possible to determine with certainty the
procedure to be followed.
Your hard disk opera hat, it emits
a metal noise of scraping or a rattling, it can undergo a crash
landing disk. To stop any intervention and to send your hard disk
for repair at a person receiving benefits equipped.
!!!!
The restoration of the files is more delicate on a crash
hard disk. You must avoid worsening the crash landing disc.!!!!
At which time the recovery of the files does prove to be impossible?
When a hard disk is completely crash, i.e. when the plates of the
disc are mainly striped. It is then a crash landing disk. But nevertheless
there is often the restoration appropriateness whatever the desperate
character:crash landing disk, flood, fire, oxidation of hard disk
etc...
List of the principal reason
of the loss of files:
- failure of the material (Reels, amplifier of read head, read
head, physical deformation of the discs, crash landing of the
heads, etc...).
- failure of the operating system.
- systems which do not start any more, failure of the controller.
- corruption caused by tools for repair.
- fall of the central processing unit or notebook.
- blow on the central processing unit or the notebook
- intentionally erased files.
- human error, accidental or desired formatting of the hard
disk.
- manufacturing defect of the hard disk.
- damaged configurations RAID.
- failures of rebuilding RAID.
- obsolescence of the hard disk.
- variations in the ambient temperature.
- damage caused by a data-processing virus.
- electric overpressure, short circuit, current failure, electric
noise of the line, etc...
- oxidation of the hard disk, damage caused by the floods
- fire
Each case is single and consequently the processes
of recovery of disc vary according to the operating system, of the
type of hard disk and its capacity. An examination of the storage
unit presenting a defect is carried out in order to identify the
nature of the dysfunction and the state of the data present.
Preventive measures :
- Try to extinguish your computer through its Operating system.
- Install an antivirus and made powerful program regularly the
updates.
- Place your equipment in the same position that that in which
you formatted the disc dur.(vertical or horizontal)
protection of the electric components:
- Use the computers in a dry place, with the shelter of the sun
and dust.
- Protection of the material of the current fluctuations by
using an UPS.
- Not to shake the hard disks and not to withdraw their lids.
- Never not to try to install or repair without having experience
necessary.
- Not to shake the hard disks and not to withdraw their lids.
- Make safeguards of the data regularly and do not store significant
data in a zone at the risk or inappropriate.
