The redundant array in the independent disks (RAID) system holds all your data. You need to take an array of actions to save your files when it fails. RAID is a complex system. Whenever something goes wrong, you face the risk of rendering your data inaccessible or lost. In certain cases, you need to regain data from RAID Hard Drives. To prevent this from happening, we have outlined some dos and don’t when dealing with a failed RAID system. But first, before we move to the main part of this post, let’s consider several of the most common RAID system failure scenarios.
When using RAIDs, you need more than several disks of redundancy and storage to protect your data. The lack of a backup system is one of the major reasons why people need data recovery. RAID systems will have failures at some point, whether it be physical or logical, like:
- Accidental deletion/reformatting
- Fire or water damage
- Failed RAID rebuild
- Controller failure
- Virus corruption
- Power surge
- Multiple disk failure
Oftentimes, RAIDs can experience several of these failures at the same time. A Physical failure may be paired with a logical one, making you take further steps to handle the problem.
Dos After Experiencing Failure:
- Stop using the RAID system when you notice an issue with it. There might be a lot of other problems and continuing to use the RAID system will overwrite internal data.
- Be cautious in order not to throw or drop the parts of the RAID system, including drives. If the RAD system experienced physical damage, any further movement can cause more severe damage.
- Disconnect the power supply after a failure. It allows us to perform the rebuild safely.
- Ensure that you carefully read all operating system messages while working with a failed RAID.
Don’ts After Experiencing Failure:
- Do not change the order of the disks as it will alter the operation of the system.
- Do not open the drives in the array and attempt a DIY recovery.
- Do not install recovery software on your array because it will overwrite the existing files.
- Do not replace the controller as it will put data in jeopardy of deletion and will not solve the root of the problem.
