Raid recovery
RAID recovery (Redundant Array of Independent Disks) is the process of recovering data on an array of hard drives that has been damaged or failed.
If one of the drives in the array fails, data may be lost or become inaccessible for reading and writing. In this case, it is necessary to apply RAID recovery methods.
There are several types of RAID arrays:
1. Partitioning of data into blocks (RAID 0): this level is intended only to increase the speed of the system due to the distribution of information on different physical drives without any integrity control.
2. Mirroring (RAID 1): each disk contains a complete copy of all data; if one of the disks fails, the others will continue to work without loss.
3. Parity/Cumulative Parity (RAID 5/6): special information encoding algorithms are used using a checksum byte, which allow maintaining access to all data after the failure of any one stored component
4. Pooling containers (RAID 10): a combination of RAID 1 and RAID 0, where data is duplicated on several drives with subsequent division into blocks.
Restoring data, depending on the type of array, can be a rather complicated process. In cases of damaged or failure of one or more disks, it is recommended to contact professional specialists for data recovery operations.
They can use specialized software tools and analysis methods to determine the cause of the failure and try to restore access to the data.
