4 Common Types of Network Attached Storage (NAS) System Failures

Network Attached Storage (NAS) is a file-level data storage server, which has many advantages over other data storage devices, such as hard disk drive. Yet, it still can fail. This article will introduce 4 common types of NAS system failures in detail.

Nowadays, more and more businesses and individuals begin preferring Network Attached Storage (NAS). It is because that through it, users can achieve additional storage capacity with ease. Also, NAS offers faster data access, ease of operation, simple configuration, native file sharing feature and so on. Nevertheless, even so, NAS system still cannot be exempt from failure as well. It can crash and fail due to various factors, thereby leading to data loss like PST corruption. In the followings, we’ll expose 4 top types of NAS system failures.

4 Common Types of Network Attached Storage (NAS) System Failures

1. NAS RAID Failure

NAS devices actually use RAID for data storage. Therefore, without any doubts, it can fail due to RAID malfunction, including overheating of hard drive in the RAID disk array, overwriting RAID configuration files, incorrect RAID setup, RAID array failure, RAID controller crash, server registry error and so on. Generally, this type of failure demands you to replace the failed drive or rebuild the RAID array. You’d better take recourse to related professionals.

2. Physical Failure

Of course, NAS system can suffer physical failure as well. This usually involves the internal hard drives. For instance, bad sectors, corrupted firmware, head crashes, drive platter damage, compromised printed circuit board, unrecognizable disk in system and failure of multiple drives can lead to NAS system failure. To deal with such failure, you have to fix the hard drive issues first of all.

3. Logical Failure

Aside from physical failure, NAS system can fail logically. For example, the device shut down improperly, or it suffers sudden power failure or voltage fluctuations, or it’s unable to boot up totally, or NAS system is reset incorrectly, etc. All of these are logical failures. Most of time, this kind of NAS system failure can be resolved with reliable and experienced software.

4. Failure by User Errors

Last but not least, Network Attached Storage (NAS) system frequently gets failed due to human errors. More specifically, you may accidentally or mistakenly delete folders or files, or format a wrong drive partition, or overwrite the database files, or incorrect manual NAS system setup. Such kind of NAS failure can result in data loss. That is one of the reasons why it is prudent to make regular data backups. In this scenario, if you have effective data backups, data recovery is pretty simple.
