A degraded RAID array is a term that refers to the failure of one or more hard drives in an array. RAID can continue to work, but with limitations. For example, a RAID 5 with multiple hard drives and a single failed drive will operate in degraded mode. In this case, disk performance suffers and Data Recovery transfer speed drops significantly.
In such cases, it is essential for system administrators and RAID users to Data Recovery from a failed RAID array to minimize downtime and the risk of losing important data. How to Data Recovery from a failed RAID array.
It is important to remember that while Data Recovery from a failed RAID array is easy, it must be done right the first time. Often the root cause of a RAID array failure is the result of other errors on other hard drives that were not visible during the RAID array failure.
It’s important to consult the hard drive manufacturer, but don’t blindly follow the advice of an unreliable helpline. In some cases, technical support suggests formatting, rebuilding or reinstalling the system. All of these suggestions can lead to loss of data that is still intact in a degraded RAID.
Therefore, to back up your systems and data, you need to back up the data stored in a RAID array. These backups are very useful, especially when they are located elsewhere – in case of a damaged RAID array, risk of fire or natural disaster.
If there is no RAID array backup, you can recover the Wikipedia data using professional data recovery software like Stellar Data Recovery Technician. After the data is fully recovered, you will be back to the original and optimal RAID array with hard drive replacement.
