Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like LaCie often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

How can data fragmentation impact the read and write speeds, and potential data loss on NAS LaCie 2big RAID (STHJ4000800 / STHJ40000800 / STHJ8000800 / STHJ36000800 / STHJ28000800 / STHJ16000800) devices?

Data fragmentation can have several impacts on read and write speeds, as well as potential data loss, on NAS LaCie 2big RAID devices. Here are the implications:

  1. Read and Write Speeds: Fragmentation occurs when files are stored in non-contiguous blocks on a storage device. This can lead to slower read and write speeds on the NAS device. When a file is fragmented, the hard drive's read/write head needs to move to different physical locations to access all the fragments, causing latency and reducing overall performance.
  2. Disk Space Efficiency: Fragmentation can also lead to inefficient disk space utilization. As files become fragmented, the available free space on the NAS device is scattered across the disk, resulting in wasted storage capacity. This can limit the amount of data that can be stored and impact the overall efficiency of the device.
  3. Data Loss Risk: Fragmentation increases the risk of data loss. When files are fragmented, the chances of file corruption or errors during read and write operations are higher. If a fragmented file is not properly stored or retrieved, it can result in data loss or data corruption, making it difficult or impossible to access the file.

To mitigate these impacts, it is recommended to regularly defragment the NAS device. Defragmentation rearranges fragmented files, placing them in contiguous blocks on the disk, which improves read and write speeds and reduces the risk of data loss. Additionally, ensuring sufficient free space on the NAS device can also help minimize fragmentation.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS 2big RAID (STHJ4000800 / STHJ40000800 / STHJ8000800 / STHJ36000800 / STHJ28000800 / STHJ16000800) can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

  1. Power off the NAS and disconnect it from the power source.

    WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.

  2. Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.

  3. Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.

  4. Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.
