Redundant Array of Independent Disks or RAID is the fastest way to recover lost data. The major goal of this technology is to protect data or avoid data. Chances of data loss are high when you store data in only one place. But with RAID you can save the same data in an array of hard disks or storage locations. So with this technology, you will not lose your data even if one of the hard disks fails. Your system will continue to work even when one or more hard disk drives have failed. raid data recovery is a complex process and it requires data recovery experts. RAID data recovery is a process of recovering and restoring data successfully from a RAID storage infrastructure
In an operating system, RAID arrays appear as a single logical hard disk. This technology works by placing the same data on multiple disks by using disk mirroring or disk stripping technique. Disk mirroring or disk stripping is nothing but, copying the same data onto different drives. Storing data in multiple disks help to increase fault tolerance and increases the mean time between failures.
Data recovery varies depending on the type of data corruption and the recovery process required to set it back. But in general, there are four steps to a successful data recovery
*1. To Repair a damaged or corrupt hard disk drive
If your hard disk is damaged or corrupt, it must be repaired and made sure that it is functional in some form, at least to an extent to read the data on it. This can be done by repairing or fixing the damaged components like a PCB, heads or a spindle motor.
* 2. Imaging the drive to a new drive or a disk image file
As the first step in data recovery, one should always create an image of the drive to ensure that there is a secondary copy of the data on another device. When a hard disk drive fails, it is very important to get the data in the drive to a safer place. Because when you continue to use a faulty drive, you are supposed to lose the data stored on it.
*3. Logical recovery of the corrupt files.
Before attempting any data recovery process, you should always copy the data on the faulty drive to a new drive. Once you have copied all available data, then you can try to attempt data retrieval from the faulty device. By using the clone or copy of the data you have made, you may try to repair the partition table or master boot record. It is also very important to read the data structure of the file system to successfully retrieve the stored data.
* 4. Repair the retrieved damaged files.
Data damage may occur when you write a file on to a sector on a damaged drive. This causes your drive to fail, and you may need to reconstruct the data to make it readable. Corrupt documents can be recovered by using suitable software or by manual reconstruction using an appropriate editor.
