Can RAID 5 Recovery Be Completed By A Layman?

raid-server-diskThe answer is in the negative. When you say layman, it means somebody who has no formal training in as far as RAID 5 recovery is concerned. In its simplest sense, it refers to ordinary people who rely on Do It Yourself instructions to do pseudo technical jobs. Given that definition of a layman, it may not be impossible to start with the recovery process but I bet the completion and its success would be the one that would be impossible to accomplish.

Any kind of RAID recovery requires enough training in hardware and software troubleshooting. The process requires the manual retrieval of images from parity lines for restoration into the original array of disks. If your Raid 5 system is composed of 3 disk drives, one of these will be utilized for the parity line. That utilized drive will store all the images that will come in handy once failure of the other operating disk drives occurs. The images from the parity lines will be arranged and stacked up together to form a sequence which will lead to full data restoration. The process is never easy. Even IT experts sometimes fail to retrieve the images and to restore the data that is lost.

More About RAID
“RAID 5 or Redundant Array of Inexpensive (or Independent) Disks that have been built in a level 5 volume set is a combination of hard drives that are designed for data to be written throughout three or more additional drives. In this kind of RAID, additional data is written to the disk in order to let the volume to be rebuilt in case a single drive fails to function. In case a single drive fails to function, the RAID 5 recovery will do its job to retrieve the data by replacing the damaged disk to a new one. The parity data will be used to rebuild the contents of the damaged disk.

Doing the RAID 5 recovery can be done in two ways. You can use the hardware or the software configuration. The difference between the two is that the hardware configuration uses a physical controller, which is usually built in the motherboard, that is responsible for the reading and writing of data within the hard drives in the volume; whereas, the software configuration uses a standard drive controller and the software utility manages the drives in the volume. Professional RAID 5 recovery is advantageous because in cases where a disk fails or has been corrupted; the data can often be retrieved through the other disks in the volume.

For the past decades, computer experts have been dreaming up ways of how to store high volumes of data without getting too expensive. Thus, they were able to find a solution in the form of RAID. It is a system developed where low cost hard drives are put together to give or provide high quality storage of data, excellent performance, and reliability over the older storage systems. Typically, there are three forms of RAID used for desktop computers. RAID 5 is the most powerful RAID form used in the desktop computer system. But a RAID 5 array may break down and there may be a possibility that data may be lost if not taken care of immediately. Once it happens, RAID 5 recovery is needed so as not to prolong the damage and for the other disks no to be affected.

The RAID 5 recovery process is somewhat complex. It is because finding the lost data is actually inclusive of various details of finding the offset and finding the stripe size. The only people who can understand these complexities would be the computer experts or the computer engineers. There are lots of data recovery companies that can be able to do these things. Hence, it is still up to the client to which company they are going to put their trust on.

If you are having problems with your drives, this means that the digital asset archive of your computer needs a recovery. This can help solve your problem before it gets worse.

RAID configurations currently has eleven levels but the most popular ones are RAID 0, RAID 1 and RAID 5. Each level provides a unique velocity and the so-called fault tolerance. Its volume combines at least three hard drives to configure data which can be later written onto three other drives. It is easily accessed by configuring it beforehand to supply information on a combination of data mirroring, data striping and data redundancy. Data mirroring helps increase the amount of data offered. Data striping on the other hand works by separating data in a certain logical order. Lastly, software for data redundancy is used to execute data in at least two tables.

Raid array setups used to be an exclusive and expensive product that was used only by applications in high-end servers. Nowadays, it is slowly being integrated into motherboards with mass production with the help of affordable drives like PATA and SATA. There are actually two types of this product. The first is the “software” RAID which is found in the current Windows version. The “hardware” RAID on the other hand has a distinct controller that you can manipulate to sustain needed information to use for the computer’s hard drive.
