If only one of the disks fails, it is easy to recover data from single RAID 5 disk since the reconstruction of RAID 5 will start immediately whenever the hard disk failure is detected.Can anyone shed some light? - asked by bonga86 on I bought 2 new drives and plugged them in but no rebuild happened as I expected. I'm not sure if the fact I had six drives in the array might save my skin. 2 drives failed at the same time and according to what I know a RAID 5 is recoverable if 1 drive fails. Recover Data from RAID 5 with 2 Failed Drives Can RAID 5 Lose 2 DrivesР”Р„ll data saved on the disks contained in a RAID 5 will be available (due to parity) unless the disks get failed suddenly.Р”В¬an I recover a RAID 5 array if two drives have failed? I have a Dell 2600 with 6 drives configured in a RAID 5 on a PERC 4 controller. In both situations, you need to follow the steps given below to recover data from degraded RAID without hesitation. If the failed disk has been pushed back online by this function, the whole array will be corrupted immediately. Despite the fact that RAID 5 can continue to work when one disk is failed and there are most RAID 5 controllers, the force online feature may ruin everything. If you try to force the array back online when there is one drive failed in RAID 5, the array tends to fail. WhatРІР‚в„ўs more, it needs to read data from all the disk drives involved when the RAID 5 array is rebuilding this may result in a second drive failure and the entire array loss.

The array rebuilding requires much time and it is likely to bring drive failure, so you may witness serious disasters during the process. If more than 2 drives are failed in the same RAID 5, the array will be broke and data will be put in danger. The biggest advantage of having a RAID 5 is: the array will continue to work even when there is one disk in RAID 5 that fails since the parity information is allocated on different drives this will not cause any data loss. The RAID 5 partition recovery can be completed as long as the data is found completely and the RAID parameters are set correctly.

The type of parity used in the RAID array.

The number of disks that have been used.

The following things need to be identified when you need to recover data from RAID: The following content focuses on RAID 5 data recovery only data recovery from other types of RAID is essentially the same.

Once you find your RAID is corrupted, you should start to recover data from RAID without any delay. The balance between performance, capacity, reliability, and availability, is different in different RAID levels.

Tip: How to recover data from a virtual disk? Three main purposes of creating a RAID are data redundancy, fault tolerance, and performance improvement (or the combination of them). RAID ( Redundant Array of Independent Disks) actually refers to a data storage virtualization technology which puts multiple physical disk drive components into one or more logical units.
