NAS Lenovo ThinkSystem ST250 Tower Server Data Recovery: Easy Steps to Follow

Lenovo ThinkSystem ST250 Tower Server NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from ThinkSystem ST250 Tower Server.

NAS Lenovo ThinkSystem ST250 Tower Server Data Recovery: Easy Steps to Follow

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 Lenovo also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Can insufficient power supply or voltage fluctuations cause data loss on NAS Lenovo ThinkSystem ST250 Tower Server devices?

Insufficient power supply or voltage fluctuations can potentially cause data loss on any electronic device, including NAS (Network Attached Storage) devices like the Lenovo ThinkSystem ST250 Tower Server.

When a server experiences power supply issues or voltage fluctuations, it can lead to sudden power loss or inconsistent power delivery. These situations can disrupt the normal operation of the server, potentially causing data corruption or loss.

Inadequate power supply can result in unexpected shutdowns, which may interrupt ongoing read/write operations and cause data to become corrupt or inaccessible. Voltage fluctuations can also cause similar issues, as they can disrupt the stability of the server's components and affect data storage and retrieval processes.

To mitigate the risk of data loss due to power supply issues or voltage fluctuations, it is recommended to use uninterruptible power supply (UPS) devices and voltage stabilizers. These devices can help regulate the power supply to the server and protect it from sudden power loss or voltage fluctuations. Additionally, regularly backing up the data stored on the NAS device to an external source can provide an extra layer of protection against potential data loss.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS ThinkSystem ST250 Tower Server can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

  • Overwriting during the recovery process;
  • Loss resulting from bad sectors;
  • User mistakes.

To create an image, do the following:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.

Where are user’s files stored?

The Lenovo ThinkSystem ST250 Tower Server network-attached storage keeps LifeLine operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.
