How does Hard Drive Recovery work?
Hard drives, like all mechanical devices, eventually break down or some of them are caused some of the Hard DIsk will crashed because of the Manufactures itself. Here are some basic possible errors.
Common hard drive problems include:
* User errors
* Software errors
* Hard drive electronics failures
* Hard drive arm failures
* Hard drive platter failures
User errors include accidentally deleting or overwriting files (these overwriting files can't be recovered) and accidentally formatting a or deleting a partition.
User errors can sometimes be resolved through the use of off-the-shelf data recovery software.
Software errors usually result from software writing data to the wrong part of the disk.
Errors cause by software are generally much more difficult for off-the-shelf data recovery software to correct. This task may require the services of a data recovery specialist. Some software can crash your Hard Disk because of the basic system requirements of the systems. So read carefully before you install the Software (For Exp. The Anti Virus Software)
Hard Drive Electronics Failures
When a hard drive physically fails, sometimes the mechanical parts of the hard drive remain undamaged. This can happen, for example, if the hard drive is subject to a power surge or a discharge of static electricity.
In these cases, it is usually possible to take the mechanical parts out of the hard drive assembly and place them into another identical hard drive unit. This should be done in a clean-room environment, to prevent dust from damaging the hard drive.
Hard Drive Arm Failures
Hard drive arm failures are very common. When the hard drive arm fails, there is a very good chance that it will damage the hard drive platters.
When you hear the clicking noises from your hard drive which signal a hard drive arm failure, back up all necessary data immediately and power the system down as soon as possible.
If the hard drive platters have not been damaged, a data recovery specialist may still be able to recover data from a hard drive with a damaged hard drive arm.
Hard Drive Platter Failures
No drive platter is manufactured perfectly. There will always be some bad spots on the platter surface. Modern hard drives automatically mark those bad spots as unusable and do not store data there.
Sometimes bad spots will develop during the life of the hard drive. The hard drive will mark that spot bad and attempt to move the data to a good spot on the hard drive. This may, or may not, result in the loss of some data.
Serious hard drive platter failures can occur as a result of hard drive arm failures. In these cases, the hard drive platters are being scratched. Your data is being scratched right off the surface of the platters! You can often hear this damage occuring. These failures are very expensive or impossible to recover.
The Solution to Hard Drive Recovery: Backup
The best method of hard drive recovery is to throw away the failed hard drive and restore your data from backup to a brand new drive.
Backing up your data is a critically important preventative maintenance task. Don't put yourself at risk by not properly backing up your data.
So the best way to escape from the crash is to Backup your weekly processes.
