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 Buffalo 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.

Yes, there are recommended practices for regular testing and validation of data backups to prevent potential loss on NAS Buffalo Drive Station HD-CE2.0TIU2 devices. Here are some key practices to consider:

  1. Regular Backup Schedule: Set up a regular backup schedule to ensure that your data is backed up consistently. This can be done daily, weekly, or monthly, depending on your needs.
  2. Multiple Backup Locations: It's advisable to have multiple backup locations to safeguard against potential loss. Consider backing up your data to an external hard drive, cloud storage, or another NAS device.
  3. Automated Backup Software: Utilize backup software that supports automated backups. This will ensure that your data is backed up regularly without manual intervention.
  4. Verify Backup Integrity: After each backup, verify the integrity of the backup data. This can be done by performing a test restore of a small subset of files to ensure that the backup is functioning correctly.
  5. Regular Data Restoration Testing: Periodically test the restoration process by restoring a subset of files from the backup. This will help ensure that your backup is reliable and that you can recover your data when needed.
  6. Monitor Backup Status: Keep an eye on the backup status and logs provided by the NAS Buffalo Drive Station or any backup software you are using. This will help you identify any issues or failures in the backup process.
