What is Data Recovery?
Data recovery is the process of retrieving lost or damaged data from a hard drive, DVD, CD, USB drive or memory card. The data recovery process typically uses a software program that can read the files even though they have been mistakenly deleted, damaged or otherwise lost in some way. Some reasons for data loss include disk failure, operating system failure and deletion.
Disk failure is the inability of the hard drive or other removable drive to read the data within. If the hard disk drive has been corrupted, for example by a virus, the recovery process will usually consist of using a software program that can read the data and transfer it to another drive. However, in these cases the hard drive will usually not work again. With some hard drives, all that is needed for the recovery of the information is replacement of some parts. If this is the case, then bringing the drive to an IT technician can usually make the drive work, thus salvaging any data that was feared lost.
Deletion of data by mistake is the usual reason for recovery needs. In some cases, such as when a user simply moves files to the recycle bin, the user can restore the data easily. However, if the information was permanently deleted, outside help is needed to recover it. Using special software can usually salvage some, if not all, of the lost information quickly and easily.
Operating system failure usually indicates the presence of a virus or other malware and in many cases, users believe their data to be lost permanently. However, in some cases, simply booting the computer using a Live CD will allow the user to transfer the information to another disk, thus completing data retrieval. Because of the complexities of the software used in the process, finding an IT professional is the best course of action when attempting any data recovery process.
