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 improper network configuration or firewall settings result in data loss on NAS Lenovo ThinkSystem SR650 V2 Rack Server devices?

Yes, improper network configuration or firewall settings can potentially result in data loss on NAS Lenovo ThinkSystem SR650 V2 Rack Server devices.

If the network configuration is not properly set up, it can lead to connectivity issues between the NAS server and the client devices accessing the data. This can result in data transfer errors, interruptions, or even complete data loss if the connection is unstable or unreliable.

Similarly, if the firewall settings are not correctly configured, it can block necessary network traffic or protocols required for data transfer. This can lead to inaccessible or lost data, as the firewall may prevent the NAS server from communicating with the client devices or other network resources.

To mitigate these risks, it is important to ensure that the network configuration is properly set up, including appropriate IP addressing, subnetting, routing, and DNS settings. Additionally, firewall rules should be carefully configured to allow necessary traffic for NAS operations while maintaining security. Regular backups of the data on the NAS server should also be performed to minimize the impact of any potential data loss.

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

Although NAS ThinkSystem SR650 V2 Rack 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 SR650 V2 Rack 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.

      The success of data recovery from a water or fire-damaged NAS Lenovo ThinkSystem SR650 V2 Rack Server device depends on the extent of the damage. In general, water or fire damage can severely affect the internal components of the server, including the hard drives where the data is stored.

      Water damage can cause corrosion and short circuits, damaging the electronic components and making data recovery challenging. Fire damage, on the other hand, can melt or warp the hardware, rendering it inoperable.

      In some cases, data recovery specialists may be able to salvage data from partially damaged components or by using specialized techniques. However, if the damage is extensive, it may be difficult or impossible to recover the data.

      It is recommended to immediately contact a professional data recovery service that specializes in handling water or fire-damaged devices. They will assess the situation and provide you with the best possible options for data recovery.
