How to recover data from NAS Promise VSky A1970rDM

Recover data from damaged RAID arrays inaccessible from a computer.

Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like Promise also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

How can regular disk health monitoring and analysis help in preventing potential data loss on NAS Promise VSky A1970rDM devices?

Regular disk health monitoring and analysis can help in preventing potential data loss on NAS Promise VSky A1970rDM devices in the following ways:

  1. Early detection of disk failures: Disk health monitoring tools can constantly monitor the status of the disks in the NAS device. By analyzing various parameters such as SMART attributes, temperature, and error rates, these tools can identify signs of potential disk failures. This allows administrators to proactively replace failing disks before they completely fail and cause data loss.
  2. Predictive analysis: Disk health monitoring tools often include predictive analysis capabilities. By analyzing historical data and patterns, these tools can predict the likelihood of disk failures in the future. This enables administrators to take preventive measures such as migrating data to other disks or replacing disks that are likely to fail soon.
  3. RAID monitoring: NAS devices like Promise VSky A1970rDM often use RAID (Redundant Array of Independent Disks) for data protection. Regular disk health monitoring can ensure that all disks in the RAID array are functioning properly. If a disk fails or shows signs of failure, the monitoring tools can alert administrators to take immediate action, such as rebuilding the RAID array or replacing the faulty disk.
  4. Performance optimization: Disk health monitoring tools can also provide insights into the performance of individual disks in the NAS device. By monitoring metrics such as read/write speeds and latency, administrators can identify disks that are underperforming or causing bottlenecks. Addressing these performance issues can help prevent data loss due to slow or unresponsive disks.
  5. Proactive maintenance: Regular disk health monitoring and analysis can help administrators identify any potential issues with the disks or the overall NAS system. This allows them to schedule regular maintenance activities such as firmware updates, disk cleanups, or system checks. By proactively maintaining the NAS device, administrators can reduce the chances of data loss caused by system failures or software vulnerabilities.

In summary, regular disk health monitoring and analysis provide crucial insights into the status and performance of the disks in a NAS device. By detecting disk failures early, predicting potential failures, ensuring RAID integrity, optimizing performance, and enabling proactive maintenance, these monitoring tools play a vital role in preventing potential data loss on NAS Promise VSky A1970rDM devices.
