In this day and age where every single information of our lives is stored electronically, we have at least had to grapple with the challenge of trying to recover lost data. Or we know somebody who has struggled to recover lost data. Data recovery is the process of recovering lost, deleted, damaged or over-written data from a storage disk that is either fixed or removable.
Data recovery strives to restore these files back to the hard drive so that they are once again accessible. It is important to note that not all data recovery attempts are successful. Sometimes the hard drive is too damaged or corrupted for any data to be recovered. The good news is that data recovery specialists keep on improving their expertise and data recovery software.
In order to understand how data recovery works, it is important to understand first how a hard disk stores data. A hard disk is a sealed, insulated storage device that is built with several components that either support the storage parts or actually store data. key amongst these components is the disk platter which is a very sensitive part such that even a single particle of dust can totally erase any data on it.
The disk platters that store data are covered in a magnetized layer and built with highly polished grass or aluminium with other materials deposited on them to realise the desired smoothness, lubrication and storage capability. Hard disks are very sensitive. Disk platters are a million times sensitive.
Well, the actual data recovery is determined by several things. One of them is the way the data to be recovered was lost. The other one is the physical state of the drive that data needs to be recovered from. The last one is the expertise of the data recovery specialist and the software to use in the data recovery process.
