Many top end computer servers used in bigger organizations come with a type of storage called RAID. RAID actually stands for Redundant Array of Independent Disks, which basically means that a number of disks work together with the capability of dividing and replicating data throughout them. This type of technology is particularly effective because it is possible for one of the disks in the array to go bad and the rest of them can continue to manage the data stored. When one of the disks goes bad, especially in a RAID 5, RAID 5 data recovery is essential in ensuring that the disk is restored to its former working capacity so it can continue to work alongside the other disks in the array.
RAID 5 technology can definitely increase data reliability and input/output performance. Although the data is distributed across the disks, the users and operating systems only see it as one single disk. There are a number of reasons why a RAID system will fail, including RAID controller failures, software RAID emulator errors, file deletion, array format, partition table related corruption, FAT corruption, MFT corruption among others. If one disk in the array fails in a RAID 5, it is simply replaced. However, considerations for replacing it or recovering the data that it stored would depend on whether or not the array is broken or in tact.
If the array is in tact, then a simple undelete software can be used to recover the deleted files. However, if the array is broken, then you would need a RAID 5 data recovery software capable of reading and treating the disks as one single array. With this kind of software, once the array has been re-created, then data recovery can proceed as normal. Basically, here are the chief working elements of a RAID data recovery software:
Even if you have no idea of what the RAID parameters are: like start sector, drive order, direction of rotation or block size, most software packages will be able to analyze your drives and determine the correct values. After which you should be able to create a copy of the reconstructed RAID on a physical drive or in a virtual image.
Most software packages not only de-stripe the RAID, but analyze it as well, thus finding the unknown parameters for you.
In a RAID 5, the minimum number of drives in the array is three. Although all drives share the data storage responsibility, it is possible that one can go bad, hence affecting the storage capability of the entire array. And this is where RAID 5 data recovery comes in, whereby through specialized work a single disc can be repaired or replaced to allow the data that was stored on it to be recovered.
RAID 5 data recovery is an essential service offered by many capable companies with the team that is professional and experienced in this specific type of data recovery. If you experience this kind of failure and are unable to sort it out yourself, consult with one of the professionals if you want to ensure that all of your data is fully recovered.
