Data recovery is a process of salvaging (retrieving) inaccessible, lost, corrupted, damaged or formatted data from secondary storage, removable media or files, when the data stored in them cannot be accessed in a normal way. Recovery may be required due to physical damage to the storage devices or logical damage to the file system that prevents it from being mounted by the host operating system (OS).
Generally, there are two types of hard drive failure: logical failure and physical failure. The logical hard drive failures appear as data corruption. Some files may seem infected or corrupted because you won't be able to access them. The most common warning signs of logical hard drive failure are missing files, failure of the system to boot, notifications indicating failure or inaccessible hard drive, or blue screen of death (BSOD).The physical hard drive failures are different, and most of the times these happen even before you realize them and can take action. Your hard drive will work till the end before shutting down, but then data recovery will be difficult. Hence, pay close attention to the subtle signs of physical hard drive failure. The most common warning sign will appear in the form of grinding or clicking noises. No doubt, this can indicate issues in other physical computer parts too, but, to be on the safe side, backup your data. Once done, shut down your PC, and take it to a professional data recovery service provider to avoid further damage.
