RAID data recovery is a technology that is known to provide increased storage capabilities and reliability when it comes to emergency data loss.RAID recovery is a form of backup where data is copied on a series of drives so that in case of failure the data can still be accessed on the drives. The term RAID stands for redundant array of independent disks.

Types of disk failure

RAID data recovery is a term that refers to the storage where replication of data on different physical drives provides an ultimate solution to data loss.The disks generally are in raid array which implies that they can only be accessed as a single disk by the operating system.

  • Logical damage

There are two main types of damages that RAID data recovery aims to rectify. The first is logical damage that occurs due to power outage when the data writing is midway. This simply implies that the final pattern on the disk will not match the structure that is expected. This causes a lot of problems when it comes to handling or even reading the disk. The best solution is a software program that will rearrange the program correctly.

  • Physical damage

Physical damage is the other type of damage that can occur on the surface of a disk drive. RAID data recovery tends to replacing some of the space on the disk surface so that the drive is readable. The technique is very costly and may result in loss of some data however, ultimately much of the data will be recovered.

Another alternative involves a special program that collects data that has remained on the disk including those that cannot be accessed by standard operating systems. The data is then compiled into a disk image file which can be written on a drive. This data tends to be close to the original file.

Challenges

The biggest challenge with RAID data recovery is the assumption that the drives will fail to work at random times. This is not always the case as multiple drives may fail in quick succession especially when the drives originate from the original production batch.

Most people who use RAID setup tend to have rigorous backup on drives that are not supported. The cost of backing up individual disks can outweigh the savings made during data recovery. This is why most users prefer to go for RAD data recovery.
