Whatever we read or write in our system the data is stored in hard disk.

How does the hard disk store data?

On each of the platters of hard disk there is a thin layer of magnetic film. Data storage on hard disks is very comparable to that of a cassette tape. Data is stored in many 1's & 0's. These binary digits are arranged in dissimilar ways to represent dissimilar characters. When these are read back via the head the data is retrieved & processed.

A system hard disk is separated into drives having main function to store the data in their drive. In which C drive is by default comes in all hard disks because all OS (Operating Systems) and software files is stored in this by default. Each drive is selected a certain space 20 GB to C drive or 40 GB to D drive this all depends of total size of hard disk. Drives names and size can be changed according to user at the time of OS (Operating system) installation.

Necessity of RAID Recovery after RAID 5 Failure



In today’s time big organizations use many top end computer servers with a type of storage media called RAID to safeguard their data. Still Raid fails. Let’s first understand what is RAID and how data recovery is possible from it.

What is RAID?
The extended form of RAID is Redundant Array of Inexpensive Disks, is contain most of the CPU machines. Raid is a collection of small, inexpensive hard disks in the form of an array. It offers a way to collect same or dissimilar data at dissimilar places on various hard disks.
RAID provides high level data storage reliability and performance with low-cost components. According to the RAID levels like RAID0, RAID1, RAID3, RAID5 etc. it can replicate your data between several hard disks. It’s a very effective technology because it is possible for one of the disks in the array to go corrupt and the rest of disks can continue to manage the stored data.
RAID 5 failed and recovery is possible.
In a RAID 5, the least number of disks in the array is three. Even though all disks share the data storage responsibility, it is possible that one can go corrupt, hence affecting the storage media capability of the all-inclusive array. And this is where RAID Recovery like RAID 5 data recovery comes in, whereby via raid recovery specialized work a single disc can be repaired to allow the data that was stored on it to be recovered.
