What is it?
Data recovery is merely the salvaging and repair of data or files that have been lost. Data loss may result from hard drive failure, data corruption, or the accidental deletion of a file. In such a case, data recovery is needed.

How does it work?
Data can be lost due to many reasons. The method that is used for data and file recovery will depend on the circumstances to which the data was lost, and the data recovery software that was used to create a backup.
Deletion of a File
When a file is deleted from a hard drive, it remains on the drive until it’s overwritten with another file. That being said, it is possible to recover a file once it has been deleted. File recovery can be completed through existing software that uses complex algorithms. Such software completes data and file recovery by analyzing and scanning pieces of information that exists on the hard drive in order to locate the missing file.
File recovery in the event that a file has been deleted is plausible, however, using one’s computer following the event of a deleted file may result in the file being overwritten and permanently lost.
Corruption of a File
In the event that a hard drive becomes corrupt and results in an error, hard drive recovery is plausible. Securing the damaged hard drive to another computer may result in the finding that only the operating system has been corrupted. With such a finding, data recovery is conceivable and may be copied to another remote hard drive.
A corrupted partition table may be repaired using appropriate software. Successfully repairing the table can easily lead to complete hard drive recovery. If recovery of the table is not successful, file recovery may still be possible though it depends markedly on the level of corruption.
Physical Drive Damage
Often best left to professionals, recovery from a drive that is heavily damaged often requires the drive to be taken apart. In a highly controlled environment, issues such as a broken controller board or a crashed head are fixed by replacing the damaged component. However, if physical damage is found to be related to the hard drive, numerous steps are required. The sophisticated software may be required to repair the corrupted parts, and the cost of rebuilding, utilizing proprietary imaging technology, and maintaining a controlled environment can result in professional data recovery to cost several thousands of dollars.
File System Damage
Formatting a file system frequently results in the destruction of information regarding previous files and structure of the disk. Depending on the system format, however, will determine the amount of data that may be able to be recovered.
Formatting with FAT, for example, may result in the destruction of large data files and the rewrite of that specific section of the disk with zeros. As a result, this significantly reduces the prospect of hard drive recovery. File systems typically vary in their probability of recovery. For instance, when overwritten with the same file system, NTFS will have a higher likelihood of recovery. Differently, other file systems have a narrower chance if overwritten with the same system. FAT files are more likely to be recovered if writing XFS over FAT is completed.
Data Recovery From Solid State Drives
Data recovery from the solid state drives is often found to be more difficult than from a traditional hard drive. However, similar techniques can be applied for data recovery. It is important to note that recovering data when an SSD crashes can be costly, estimating to be a couple thousand dollars.
Companies/business in the United States that do that service/topic?
There are many data recovery services that can help individuals access valuable lost data. ACE Data Recovery services the needs of people across multiple states and provides nationwide data recovery technology.
SERT Data Recovery offers the technology and experience necessary to recover data and important files. SERT Data Recovery coincides with the HIPPA regulations, taking privacy into serious consideration.
How much does it cost?
The cost of data recovery varies depending on the extent and cause of the damage. Depending on your media, what has gone wrong, and the work required in order to secure and retrieve the files you need may vary from a few hundred dollars to a couple thousand. It is important to consider that the first attempt at data recovery will always yield the highest amount of success. Then, initially choosing the best data recovery provider and method is important.
Why does it happen?
Data loss can be a result of numerous causes, such as human error, equipment failures or malfunctions, accidental deletion of data, unintentionally formatting a hard drive, software crashes, firmware corruption, or even simple human error. Data is often valuable, and the need for data and file recovery is necessary to salvage the valued information.
Is it useful to you?
Data recovery software and the hiring of specialists can result in recovery of files, data, and hard drives. Some data recovery specialists can retrieve data from storage media that is determined to inevitably destroyed. Data recovery can be plausible when a file or a piece of data once existed on your hard drive, USB, RAID, storage media, or SSD. Data recovery, the salvaging, and repair of data is indeed possible.
