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 QNAP 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 data fragmentation impact the read and write speeds, and potential data loss on NAS QNAP VS-4108 Pro+ devices?

Data fragmentation can have several impacts on read and write speeds, as well as potential data loss, on NAS QNAP VS-4108 Pro+ devices. Here are some potential impacts:

  1. Read and Write Speeds: Data fragmentation can lead to reduced read and write speeds on the NAS device. When files are fragmented, the device needs to access multiple physical locations on the storage media to retrieve or write the data. This can result in increased seek times and slower overall performance.
  2. Disk Fragmentation: As data is constantly written and deleted on the NAS, the files can become fragmented on the physical storage disks. Disk fragmentation can further exacerbate the read and write speeds, as the device needs to perform additional disk operations to access the fragmented data.
  3. Data Loss: Fragmented data can also increase the risk of data loss. If a file is fragmented across multiple locations and one of those locations becomes corrupted or inaccessible, it may result in partial or complete data loss. Additionally, if the file system metadata becomes fragmented, it can lead to difficulties in locating and recovering files in case of data corruption or hardware failures.

To mitigate these impacts, it is recommended to regularly defragment the NAS storage. QNAP devices often provide built-in defragmentation tools or options to schedule automatic defragmentation. Defragmentation rearranges the fragmented data on the storage media, optimizing the file placement for improved read and write speeds. It also helps in reducing the risk of data loss by consolidating the file fragments and improving the overall file system integrity.

However, it is important to note that defragmentation can be a resource-intensive process, potentially impacting the NAS performance during the defragmentation process. Therefore, it is advisable to schedule defragmentation during periods of low usage or plan it accordingly to minimize disruption.

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

Although NAS VS-4108 Pro+ 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 QNAP VS-4108 Pro+. 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.

How to recover data from a QNAP

VS-4108 Pro+ has 4 HDD slots, and it supports the following array types:

  • RAID 6;
  • RAID 5;
  • RAID 10;
  • RAID 0;
  • RAID 1;
  • JBOD;

NAS supports:

  • ZFS;
  • EXT4;
  • EXT3;
  • exFAT;
  • FAT32 (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 QNAP VS-4108 Pro+ network-attached storage keeps QTS (QuTS hero) 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.
