Wortmann Terra NAS Recovery

Attingo is recovering data from Wortmann Terra Systems on a regular basis. In over 98 percent of cases the data can be successfully restored. Data rescue is solely performed by experienced specialists in our in-house clean room laboratory. Common causes for data loss are firmware errors or defect of one or more hard drives (dependent on the RAID level).

We can help you by recovering data from the following models:

•  TERRA NASBOX
•  TERRA SAN

NAS Data recovery: Wortmann Terra

Wortmann Terra NASBOX and SAN are popular because of their relatively low maintenance effort. This is also why they are often used in small and medium-size enterprises as well as in private households. Aside from 1-bay NAS devices, the hard drives inside the NAS can be interconnected to a RAID array. Wortmann Terra 2-bay NAS devices RAID 1 (mirror) and RAID 0 (stripe) are the most common. RAID 5 configuration (3 hard drives or more) is used with Wortmann Terra 4-bay NAS servers. Some 4-bay NAS devices even allow RAID 6 (4 hard drives or more). From RAID level 1 onwards, access to the data is still possible and data security is granted even after the failure of one hard drive. With RAID 6 two HDDs may drop out. If several hard drives fail at the same time due to mechanical or electronic defects, data loss is predestined.

Possible causes for NAS hard drive failure

Wear and tear and material fatigue

From experience, network storages run in continuous operation and often work with mechanical hard drives which are not suitable for long-term operation. Through frequent read/write accesses normal wear marks occur significantly earlier and lead to the defect of one or more hard drives. Hard drive wearout is the most common reason for defects on electronic and mechanical components.

Improper Handling

During its life span a Wortmann Terra NAS will very likely be exposed to improper handling and physical influences (fall, shock, concussion). This may affect the the integrated HDDs and foster mechanical defects (read/write heads, surface damage).

Electronic damage after overvoltage

As Wortmann Terra NAS are usually run in continuous operation, the power supply also needs to be uninterrupted. In case of lightning storms and lightning strikes the NAS and its hard drives can be damaged. Another possible scenario are false or defective power supply units causing overvoltage.

Thermal factors

If the Wortmann Terra NAS isn't cooled down properly, overheating is a common consequence. The heat affects the hard drives which are very sensitive to extreme thermic alteration (material extension, air cushion changes), so severe mechanical damage may be the result.

Other possible causes for data loss from Wortmann Terra NAS

Lost data after a firmware update

As any manufacturer, Wortmann Terra provides firmware updates for its NAS servers. In some cases the this can cause the NAS to re-initialize or alter the configuration, which leads to data loss.

Wortmann Terra NAS RAID configuration deleted

When a new RAID volume is created on the NAS (e.g. RAID 0 to RAID 1) the previous configuration gets erased, the hard drives get formatted and a new volume and file system gets created. All the previous data and releases are deleted in the process. If new data is saved on the NAS afterwards, the previous data will be gradually overwritten.

Wortmann Terra NAS error messages:

• Hard drive display is blinking (red): Hard drive error/hard drive defect
• System warning light is blinking (red): System error
• Warning light is blinking (red): System cooling error
• Disks information: Warning/failed

Damage limitation with Wortmann Terra NAS systems

• Avoid reboots, rebuilds, chkdsks or similar operations. They can lead to fatal consequences.
• Don't perform any further installations and don't save any new data.
• Remove and label the hard drives with their slot position.
• Tell us the exact model name of your NAS, the capacity of the hard drives and the configuration of the NAS system.
