Data recovery simply means the salvaging or securing of data from failed or compromised hardware systems. The term refers to techniques for obtaining “hard to get” data, usually during hardware or system failures, or when system data has been erased. Hard drive data recovery after a system failure is easily possible for anyone.
You don’t have to be a certified computer technician to recover data from the corrupted hard drive, but you ought to use proper tools. Most importantly, No two data recovery situations are the same. Most often, it’s possible to completely recover lost files from a hard disk drive, including the original filenames and folder structure.
Other times, the files and data may be recovered, but the filenames, date/timestamps and folder paths are lost. And in some cases, no intact files can be found. This is why it’s of maximum importance that no new files are written to a disk prior to attempting a Data recovery. If the data on the disk is overwritten, then the old data is gone. No program or commercially available data recovery service can recover it.
Recovering data from the hard drive requires either a deep knowledge of the Windows file systems, FAT and NTFS, or the hard drive data recovery tools. The data recovery tools are widely available on the market, and choosing the right tool for hard drive data recovery can be tricky. Also parts of the newly designed or modern computers are amazingly reliable, yet they still fail for various reasons.
Stretching the consistency by overclocking making it possible for overheating is a common reason for data corruption and loss of files. Power failures also cause problems, leading the list of reasons for system failures and data corruption. Software errors and malicious software also contribute to the growing list of disasters waiting to turn out your precious data.
For files that have not been overwritten, Data recovery method is simple with the use of data recovery software. This is File recovery through analysis of the information about files and folders. It is the first method that a file recovery program attempts to carry out. This is because it can recover files with their original names, paths, date/time stamps, and their data if successful.
The file recovery software starts by trying to read and process the first copy of the information about files and folders. In some cases, it is the only step that needs to be taken in order to recover files. If the first copy of the information about files and folders is severely damaged, the software scans the hard disk drive for the second copy of the information about files and folders.
It also attempts to pick up additional information about the folders and files structure that may be on the data part of the disk. Then, it processes all this information to reconstruct the original folders and file structure. If the file system on the disk is not severely damaged, it is always possible to recover the entire file and folder structure.
If the file system on the disk is severely damaged, this recovery method cannot recreate the entire folder structure. Then recovered files will appear in “orphaned” folders.
