RAID 1 Data Recovery Service from True Industry Experts

RAID 1 is a Redundant Array of Inexpensive Disks (RAID) that is in a mirrored set. Mirroring provides redundancy, so if one drive fails, it can be accessed on the other drive. If your organization experiences RAID 1 failure, a professional may still be able to recover that information.


Understanding RAID 1

RAID 1 volume requires at least two hard drives. When data are written to one drive, the exact information is also written to the second drive at the same time. In the event of drive failure, the healthy hard drive can function alone without losing information while the other is replaced. This provides data redundancy.

RAID 1 drives provide fast read and write speeds. It is simple technology, and if a drive fails, it just needs to be copied. Since the exact information is duplicated in two places, drives can’t store as much data. For example, if a system uses two one-terabyte drives, only a single terabyte is available for storage because the system must store two copies of the same material.

Another disadvantage of RAID 1 volume happens when disks receive damaged or corrupted data. That data isn’t just stored in one location because it is written to the duplicate drive. RAID 1 solutions often require systems be powered down during drive replacement, which can impact productivity. Systems may require a hardware controller to enable hot swapping.

Business owners and individuals assume they are protected against data loss when they have duplicate data sets, but that is incorrect. If users delete files in one location, the array simultaneously deletes them from the second. If one file becomes infected, the infection transfers to the other, as well. RAID systems can promote up time, but they do not remove the need for regular data backup.

When RAID 1 Fails

Daily wear-and-tear, poor ventilation that causes high temperatures, impact and accidental spills might cause drive failure. Sometimes a manufacturer defect, logical failure or virus damages systems. When one drive fails, many times the information can quickly be recovered through a high-level reformat. Recovery software is available, but it is not a safe approach. It could implement processes that cause surfaces of the original disk to be rendered useless. Safe recovery involves creating block-level reproductions of each hard drive sector, then using that to reconstruct the original volume.

What if Both Drives Fail?

Electrical surges, natural disasters or other catastrophes can cause both drives to fail at once. Much of the time, if the drives were creating mirrored volume at the time of the failure, experts can still extract it, since there are two sets of the same information.

It depends on the RAID level and your knowledge of the system. If it is a complicated setup that you are unfamiliar with or feel uncomfortable at all, contact a data recovery RAID professional immediately, especially where critical information is involved. In the event of a single hard drive failure in a redundant RAID type where the data is still accessible, replace the failed drive with an exact spare and let it rebuild the array. If you have a second failure, or you have hot spares set up and you are unsure of the order of the drives, you will only make matters much worse or even unrecoverable if you try to replace or rebuild drives. Whatever you do, do not reinitialize your system if you are concerned for you data.

We have seen countless situations where staff that is not completely familiar with their systems, try to ‘fix’ the problem but only make it impossible to perform a RAID data recovery. In most of these situations, it would have been possible if they contacted a data recovery professional before trying to reinitialize.
