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

Are there any specific system logs or event notifications to monitor for early detection of data loss on NAS Buffalo TeraStation TS-RVH12TL/R6 devices?

Yes, there are specific system logs and event notifications that you can monitor for early detection of data loss on NAS Buffalo TeraStation TS-RVH12TL/R6 devices. Here are some key logs and events to monitor:

  1. RAID Array Status: Monitor the RAID array status logs to detect any issues with the disk drives or RAID configuration. Look for any warnings or errors related to disk failures, degraded performance, or rebuild processes.
  2. Disk SMART Status: Check the SMART (Self-Monitoring, Analysis, and Reporting Technology) status logs of each disk drive in the NAS. SMART logs provide detailed information about the health and performance of the drives. Look for any warnings or errors indicating potential disk failures.
  3. File System Errors: Monitor the file system logs for any errors or inconsistencies. File system errors can indicate data corruption or other issues that may lead to data loss. Pay attention to any warnings or errors related to file system checks or repairs.
  4. Backup Status: Monitor the backup logs and event notifications to ensure that regular backups are successfully completed. If backups fail or encounter errors, it may indicate potential data loss risks.
  5. Disk Usage and Capacity: Keep track of the disk usage and capacity logs to identify any sudden spikes or abnormal behavior. If the disk usage reaches its maximum capacity or increases unexpectedly, it may lead to data loss due to insufficient storage space.
  6. Network Connectivity: Monitor the network logs to ensure a stable and uninterrupted network connection. Network connectivity issues can disrupt data access and may result in data loss.

Additionally, you can configure email notifications or alerts for these logs and events, so you can be promptly notified if any potential data loss risks are detected on your NAS Buffalo TeraStation device.

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

Although NAS TeraStation TS-RVH12TL/R6 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.

TeraStation TS-RVH12TL/R6 has 4 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • RAID 5;
  • RAID 6;
  • JBOD;

NAS supports:

  • exFAT, VFAT, FAT 12 / 16 / 32;
  • NTFS / ReFS;
  • 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 Buffalo TeraStation TS-RVH12TL/R6 network-attached storage keeps OS Linux 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.
