subject: Recover Data After Physical Damaged Hard Drives [print this page]
Accidents do happen all the time. Most people have experienced a loss of data. That files could be so important as if you have suffered a personal loss.Hard drive crashes will lead tohardwareorsoftware failures. Even to the most severe case, thefile system corruption.
Although there is some confusion as to the termhard drive data recovery,it can also be the process of retrieving and securing deleted information from a storage media for forensic purposes or spying. To be more specific,
Data recoveryis the process of salvaging data from damaged, failed, corrupted, or inaccessiblesecondary storage mediawhen it cannot be accessed normally. Often the data are being salvaged from storage media formats such ashard disk drives,storage tapes, CDs, DVDs, and other electronics.Recoverybeing processed due to physical damage to the storage device or logical damage to the file systemthat prevents it from being mounted by the host operating system. Physical damage can be caused by a variety of failures. Hard disk drives can suffer any of several mechanical failures, such as head stack crashes and failed motors; tapes can simply break. Physical damage always causes at least some data loss, and in some cases the logical structures of the file system are damaged as well.
Recovering data after physical damaged hard drives: most physical damage cannot be repaired by end users. For example, opening a hard drive in a normal environment can allow airborne dust to settle on the media platter and being caught between the platter and the read-write head, causing new head crashes that further damage the platter and thus compromise the recovery process. End users generally do not have the hardware or technical expertise required to make these repairs. Consequently,data recovery companiesare often employed to salvage important data. Nevertheless, it will also go with the resulting risk of being processed by a third-party company without supervision.
In 2008, Data Compass succeeded in research and development of Mobile ElectronicData Recovery Devicewhich possesses high intelligence and can be easily mastered by a common computer operator, which prefigures that this device will be a must for government departments and companies' choice of data security in the future. Data Compass not only solved those problems that storage media software and hardware cannot be repaired in the past yet therecovery deviceis too huge to remove, also help government implement electronicgovernment information recoveryunder interior transfer, that maximally protect government's confidential data security through processing in-house and real-time data recovery, generally evade and eliminate government and companies' fear of uncertain cases underdata-level management.
It is noted that there are many accounts of users getting a bad disk going long enough to pull their data off, often via slightly bizarre tricks. These include making the drive cold (in the freezer) or spinning it manually on the ground, both actions being used to unstick a jammed media platter. However, most data recovery professionals disapprove the use of tricks such as these, since they can cause additional physical damage to the drive.
Do not attempt recovery yourself on severely traumatized drives. This may cause further damage or permanent data loss.
