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.

How can the number of drives in a NAS Lenovo ThinkSystem SR650 Rack Server device's RAID array impact data recovery and potential loss?

The number of drives in a NAS Lenovo ThinkSystem SR650 Rack Server device's RAID array can impact data recovery and potential loss in the following ways:

  1. Data recovery: The more drives in the RAID array, the higher the chance of successful data recovery. RAID arrays with more drives often use higher RAID levels like RAID 5 or RAID 6, which provide redundancy and allow for data reconstruction in case of drive failures. With more drives, the array can sustain multiple drive failures without losing data.
  2. Potential loss: If the RAID array has a smaller number of drives, such as RAID 0 or RAID 1, the potential loss of data increases. RAID 0 does not provide redundancy, so if one drive fails, all data on the array is lost. RAID 1 mirrors data across two drives, but if both drives fail simultaneously, data loss can still occur.
  3. Rebuild time: When a drive fails in a RAID array, the remaining drives need to rebuild the data onto a replacement drive. With a larger number of drives, the rebuild time can be longer, increasing the risk of another drive failure during the rebuild process. If another drive fails during this time, data loss can occur.
  4. Performance impact: The number of drives in a RAID array can also impact performance. RAID arrays with more drives can provide higher data transfer rates and better overall performance. However, if the number of drives is too high, it can lead to increased latency and decreased performance due to the complexity of data striping and parity calculations.

In summary, having more drives in a NAS Lenovo ThinkSystem SR650 Rack Server device's RAID array generally improves data recovery chances and reduces the potential loss of data. However, the specific RAID level and configuration should be carefully chosen based on the desired balance between performance, redundancy, and data protection.

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

Although NAS ThinkSystem SR650 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.

  • APFS / HFS+;
  • Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
  • VMFS / HikvisionFS;

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 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.

    Is it possible to recover data from a NAS Lenovo ThinkSystem SR650 Rack Server device that has undergone a file system conversion or re-partitioning?

      It is possible to recover data from a NAS Lenovo ThinkSystem SR650 Rack Server device that has undergone a file system conversion or re-partitioning, but the success of the recovery depends on various factors such as the extent of the changes made to the file system and the actions taken after the conversion or re-partitioning.

      If the file system conversion or re-partitioning process did not overwrite the data on the device, there are data recovery tools and services available that can help recover the lost data. These tools can scan the device and attempt to reconstruct the file system or recover individual files based on their signatures.

      However, if the conversion or re-partitioning process involved formatting or overwriting the data on the device, the chances of successful data recovery decrease significantly. In such cases, it is recommended to consult professional data recovery services as they may have specialized tools and techniques to recover data from formatted or overwritten storage devices.

      It is important to note that data recovery can be a complex and time-consuming process, and there is no guarantee of 100% success. Therefore, it is always advisable to regularly backup important data to avoid the risk of permanent data loss.
