Recovering From Hard Drive Failure-ssdao

Data-Recovery Every .puter user should understand that hard drive failure is a very real possibility. Just like any other piece of equipment, .puters are mechanical and will fail and will need to be repaired or replaced. Some .ponents, such as monitors, keyboards, optical drives, do not present much of a challenge and can be replaced easily on most .puters, especially desktops. Even the motherboard, memory cards, network cards, and similar .ponents do not present a major problem. When any of these .ponents fail you havent really lost anything; you just need to replace them. But when a hard drive fails, you have quite a different situation. Not only do you have a physical .ponent broken, but you also face the loss of irreplaceable data. You can just pop in a new CD Rom drive or memory card; replacing your data could mean recreating it, word for word, unless the data can somehow be recovered. Fortunately, many times the data can be recovered from a failed drive. How effectively and .pletely the recovery is depends on the failure type. Physical failures are caused by drive .ponent failure, including read/write head damage caused by wear or abuse, and electronic .ponent failure, caused by voltage spikes or overheating. Logic failures are caused by damaged or altered file structures and can be the result of virus infection, program failure, or improper registry changes. Logic failures are often easier to recover since all the data is still there, it just cant be read. If you must take your ailing drive to a data recovery specialist , you should understand that drive recovery may require different procedures for different types of systems. For example, if laptop hard drive recovery is needed, you should take the entire .puter to the recovery service technician. Disassembly of a laptop, if necessary, can be .plicated. NTFS file recovery can be done with the drive still installed in the machine. The NTFS file system is the file system used on newer Windows-based machines. This type of recovery is generally a logical failure and the files are recovered using special software. Raid drives are banks of smaller hard drives that are configured to work as a single drive. These systems are used extensively in server applications. Depending on the Raid configuration, Raid hard drive recovery may require that all the drives must be sent to the recovery specialist, not just the failed drive. The Raid controller may need to be included, also. Your best defense against hard drive failure is to keep a working, updated backup of all your important, irreplaceable data. Unfortunately, while most data can be recovered, it is still possible that some files may be permanently lost. Effective backup procedures are your only safeguard against permanent data loss.
