RAID 1 mirroring is a standard RAID level in which hard disks are arranged in a way that creates an exact data copy on two or more hard disks. If either of your hard drive fails, the other hard drive(s) in the array can be used and the RAID array will continue to function. RAID 1 is useful when compared to storage capacity, you require performance and reliability. But at times, computers using RAID 1 show abrupt behavior. It can occur when its file system gets damaged. In such cases, you need to use your recent data backup to restore the lost or inaccessible data. However, if data backup is invalid, incomplete or not available, you need to consult data recovery services for perfect technical assistance and recovery.

As a practical instance, you might receive the following error message when using RAID 1 mirroring on your Windows computer:

"An I/O failure occurred on DeviceHarddiskmFtn"

After the occurrence of the above error message, you can’t access your data.

Cause

The above error message is encountered due to mirrored file system damage. Due to a writing error if a conflict occurs with the mirrored file system, it might get damaged. If this writing error is limited to one mirrored hard drive, you may still access your information from the same sector on the mirrored hard drive.

Solution

To solve the above issue, you need to follow these steps in order:

• Use chkdsk utility to repair file system corruption. It is a command-line tool that you can use to fix file system errors.

• If the problem persists and you can’t access your data, you need to consult a Data Recovery company to recover the lost data.
