Common Causes of RAID Failure

A RAID system is a group of multiple hard disks that works for an operating system as a storage device. This storage technique was first used in 1980s and is still extensively used today.

Though RAID arrays are said to be a reliable and stable way of managing and accessing data, like any other type of hard drive, they also experience breakdowns once in a while. The consequences from such breakdowns can be significant, which can be a reason of permanently losing valuable documents and files. This problem can be more frustrating if you have not performed regular backup procedures to secure all stored files. RAID users are often fooled by the false notion of security about data loss since RAID arrays are said to be more dependable than modern single drive systems, but unfortunately, even the best structured and highly secured RAID configuration can fail.

If you happen to experience RAID array failure, there’s still a possibility that you can retrieve all your data with the assistance of a Singapore data recovery expert and provided that you do all the precautionary steps to keep your computer and data protected.

Get to know the 3 common causes of RAID system failure and know what to do to increase chances of recovering your stored data.

  1. RAID Controller Failure

    Most RAID systems solely depend on one controller to be able to operate. From time to time, the controller fails to work properly because of various reasons. With this problem, the unit can cause booting up problems and other operational difficulties.

  2. Failed Reconstruction of RAID VolumeIf the RAID system’s volume is not reconstructed correctly, problems in accessing data may be experienced, or worse, it can lead to total system breakdown.
  3. Multiple Disk Failure

    The purpose of the installation of multiple disks is to keep the server working even under a single disk failure.  However, allowing the failed disk to stay in the system can affect its performance and make the whole server more vulnerable to further failure. Letting the system run in corrupted mode only increases the possibility of array failure, taking all your important data with it.

What to Do In the Midst of Array Failure

When you suspect a system breakdown that is about to happen to your RAID array, turn it off immediately. In any hard drive failure, it is always recommended to turn them off immediately erroneous processes from running and prevent further loss of data.

It also helps if you don’t do any attempts of physical repair yourself. Seek assistance from a Singapore data recovery expert who has the right tools and skills to properly repair your RAID system and retrieve all your files. The earlier you do this, the higher is your possibility of recovering your stored files and documents.
