Data stored on your computer may be lost due to some mechanical reasons like head crash, failure of the disk controller device, a power surge, or due to a defective air filter. It may also be due to software related problems like virus problem, problems in the operating system, file corruption, or accidental erasure. In all these cases recovery and backup services is an absolute necessity.
Once any of these problems occur, access to data will be denied to the user in the ordinary way through the computer. In some cases data can be permanently lost as well. It is only access to it through the normal path that is denied and data can be retrieved through some other means. This method is known as hard disk recovery.
One possible way of reducing the potential of disk failure and the resulting need for hard Disk Recovery is using the technology of Redundant Array of Independent Disks, which is better known by its acronym RAID. In this way data is replicated and stored in different hard drives. The computer takes these small hard drives as a single storage unit. This adjustment provides more storage space and speeds up the computer, and gives the machine more fault tolerance.
The use of RAID is not a perfect solution for data loss. The benefit of RAID from a data recovery and backup services requirement outlook is that the data will be more intact even if one of the drives fails.
The word RAID was initially expanded as Redundant Array of Inexpensive Disks though later the word inexpensive was altered into independent. There are various RAID levels and some of the levels use striping, which is an interleaving process whereby multiple disks are reading and writing at the same time. This arrangement makes hard disk data recovery process from a RAID bit more complicated than that from a single large disk. Data is retrieved in almost all cases even though RAID data recovery may turn out to be more costly for the customer.
Whenever disk damage is limited, connecting the damaged disk to another hard disk as a slave can recover data. There is also data recovery software used by data recovery and backup services providers, which is extremely useful in most cases of data recovery. There are minor differences in the recovery software used for different operating systems like Linux, UNIX, Windows, etc. Some of this software is available online.
When hard disk failure occur due to mechanical reasons like a head crash, recovery using software may not be possible always. The damaged parts of the drive will have to be replaced in such situations and data will have to be retrieved from the reconstructed drive. This is a somewhat complicated process but many recovery and backup services provide the required help, thereby saving most of the data.
