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 Synology 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 regular data integrity checks help prevent data loss in NAS Synology Rack Station RS815RP+ / RS815+ / RS815 devices?

Yes, regular data integrity checks can help prevent data loss in NAS Synology Rack Station RS815RP+ / RS815+ / RS815 devices. These devices typically come with built-in data integrity features such as RAID (Redundant Array of Independent Disks) and SMART (Self-Monitoring, Analysis, and Reporting Technology) to ensure data reliability and prevent data loss.

RAID technology allows for data redundancy by distributing data across multiple hard drives, ensuring that if one drive fails, the data can still be accessed from the remaining drives. Regular data integrity checks can help identify any potential issues with the RAID array, such as failed drives or data corruption, allowing for timely repair or replacement.

SMART technology monitors the health and performance of hard drives by tracking various parameters such as temperature, error rates, and bad sectors. By regularly checking the SMART status of the drives, you can proactively identify any signs of potential drive failure and take appropriate action, such as replacing the drive before it completely fails and causes data loss.

In addition to RAID and SMART, Synology NAS devices also offer various data protection features like data scrubbing and data checksums. Data scrubbing periodically verifies the integrity of data stored on the drives, ensuring that all the data is accessible and error-free. Data checksums, on the other hand, generate unique signatures for files and compare them during regular integrity checks to detect any data corruption.

By regularly performing data integrity checks and utilizing the built-in data protection features of Synology NAS devices, you can significantly reduce the risk of data loss and ensure the integrity of your data.

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

Although NAS Rack Station RS815RP+ / RS815+ / RS815 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.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Synology Rack Station RS815RP+ / RS815+ / RS815. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

  • Synology Hybrid RAID (SHR);
  • RAID 6;
  • RAID 5;
  • RAID 10;
  • RAID 1;
  • RAID 0;
  • Basic;
  • JBOD;

NAS supports:

  • Btrfs;
  • EXT4;
  • EXT3 (External Disk Only);
  • FAT32 (External Disk Only);
  • exFAT (External Disk Only);
  • NTFS (External Disk Only);
  • HFS+ (External Disk Read Only);

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 Synology Rack Station RS815RP+ / RS815+ / RS815 network-attached storage keeps DSM (DiskStation Manager) 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.
