RAID array failures
Here, let's consider the most common problems and errors of arrays at various levels:
RAID controller failure: Since the controller is one of the most important components of the array, its damage or failure will lead to sad consequences. Unfortunately, the array is most often damaged due to a faulty controller. Sometimes, even the most proven controllers are subject to voltage drops, a sharp power outage, etc. This is a weak spot for controllers, as a result of which they stop working.
RAID rebuild/reassembly error: The correct rebuild of the array and its restoration is the key to success for your data. If a force majeure event occurs during these actions, most likely you will lose access to all the data of the RAID.
RAID array disk failure: It is known that most arrays can deal with damage to a single drive without data loss. However, it can also lead to another disk crash on the array. In this case, automatic recovery will no longer help. Depending on your array level, if two or more disks are damaged, you will lose some of the data or all of the accumulated information.
RAID partition missing: If the storage mechanism (namely, striping) is damaged for some reason, this will cause the partitions to be inaccessible or not defined at all in the array. In this case, the data will also be unavailable.
Server death: The host computer is also vulnerable, and if any failure occurs on it, it will affect the array and access to the data will be impossible.
These errors are the main ones when the array is damaged. In order to return data in this case, you will need to try several options. But do not rush to leave this page, because it is here that the simplest and most effective way to return all the lost information is described.
Save data after RAID array failure
DiskInternals RAID Recovery is a leader in recovering a damaged array and can easily deal with all the errors described above. This application was one of the first tools for RAID recovery and has more than 15 years of experience benefiting its customers. The program automatically determines the type of source RAID array controller, the number of disks, and other important characteristics of the array, while at the same time providing fully manual or automatic data recovery where possible. A free preview before export is a great opportunity to verify the effectiveness of the application and the quality of the recovery.
Be sure to use these instructions when working with the application to correctly execute it.
To get started, download RAID Recovery, and then install the software on Windows.
Open RAID Recovery. If necessary (if you do not have enough skills), turn on the Recovery Wizard.
Then be sure to select the desired array to scan.
In a new window, select a scan mode:
- Quick Recovery Mode: this won’t take much time
- Full recovery mode: longer, but deeper scanning
Now the program checks the current state of the RAID array, as well as the file system of the controller, and restores files where possible.
Then comes file preview.
Now you are sure that your data has been restored properly. Purchase a license for RAID Recovery and export the recovered files to any source connected to the system. You also get free technical support by company specialists in any future difficult moments when working with the application.
