Right now, most companies use systems RAID to improve the performance and security of your environments. This “redundant independent disk array”, as it stands for, optimizes the storage and processing capacity of a computer. It does this by understanding several hard drives connected to a single logical drive, from which the functions are indicated. And although it usually works well, various errors can appear. So we’re going to teach you how to deal with common RAID flaws, and what you need to do to get around these issues.

Without going into more detail about the common RAID problems, which we have already analyzed, we can clarify that there are seven different levels. These are the ones that go from RAID 0 to RAID 6. Thanks to them, the data division occurs uniformly on each of the disks. But if one fails, the others will fail, causing massive data loss. This, even when each of the levels has its own protection. This is useful many times, but cannot guarantee the security of the content.

The worst thing that could happen to you, then, is that the data stored in RAID arrays becomes inaccessible. Well actually the worst thing is that they are permanently removed. If you add to this that a huge number of people do not endorse their data, at least monthly as they should, the proportion of tragedy that can occur on your computer is, then, difficult to explain.

Most Common Causes of RAID Failures

The first thing, to keep you a little calmer, is to remember that most RAID arrays are fault tolerant. However, it is also important to note that they are all vulnerable to hardware and software failure. There are several reasons why these errors occur.

They can have to do with hardware failures, software failures, application failures and even processes that we have improperly executed. This can affect the controllers, the power supply, generate overheating, etc. In the worst case, the stored files are corrupted and become permanently inaccessible or corrupted.

And what to do to avoid data loss?

Backups, always out

If you have your backups or backups off the disk, you will not have problems with RAID failures. This is because, even when RAID systems are known for their reliability, their data may disappear due to the reasons we have stated before.

Your backups must remain on external hard drives or in the cloud.

Stop using RAID

If your problems with RAID are repeated, perhaps it would be best if you abandoned this mechanism. This is the main recommendation to avoid loss of content in the long term. A good option may be to switch to AHCI. We also advise you not to download and install content recovery software, because it can overwrite information about your files.
