In this case, a client contacted us after discovering that files and folders had disappeared from their Buffalo LinkStation NAS. Despite the drive being visible on the network, entire directory structures were missing. The symptoms pointed to either a malware infection or a corrupted file allocation table, both of which are known issues with certain LinkStation firmware versions and SMB network configurations.

🔧 Common Symptoms

  • Folders visible previously now missing from shared network path
  • NAS device accessible via web interface or IP address
  • File count appears incorrect or significantly reduced
  • Antivirus scan shows infection on network share
  • “Disk full” or “no data found” errors on folders
  • LinkStation drive appears healthy in admin panel but content is empty

🛠️ Step-by-Step Recovery Process

1. Initial Analysis and Drive Imaging

Buffalo LinkStation devices often use Linux-based file systems like EXT3, EXT4, or XFS and store data on internal SATA or NAS-specific drives.

Our engineers began by:

  • Removing the internal drive(s) from the NAS enclosure
  • Write-blocking each disk to prevent overwriting any data during diagnostics
  • Imaging the disks using forensic recovery hardware (DeepSpar / PC-3000) to preserve all accessible sectors, including deleted or unallocated space
  • Logging SMART data and scanning for bad sectors or early warning signs of physical failure

2. File System Analysis

Once we had clean disk images, we examined the file system:

  • In this case, the volume used EXT4, commonly used in Buffalo firmware
  • Folder structure corruption was confirmed – directory entries were either deleted or marked as free space
  • The file allocation table (inode map) was partially overwritten or damaged due to malware activity or OS-level logical corruption
  • There were no physical drive issues, confirming it was a logical failure, not hardware

3. Data Recovery from Inode Table and Journal

To recover the lost files:

  • We used inode scanning tools to parse the file system and locate previously deleted or hidden files
  • File entries were reconstructed using journal recovery, allowing us to roll back filesystem activity to a known working state
  • Lost directories were rebuilt using file signatures and metadata where possible
  • All files were extracted to a new volume, retaining original folder structure, file names, timestamps, and permissions where recoverable

4. Malware Remediation (Optional)

If malware is confirmed, we offer the option of:

  • Providing a clean backup of the data in a standard NTFS format on a new external drive
  • Advising on network hardening, such as disabling anonymous SMB, firmware updates, and isolating NAS devices from insecure endpoints
  • Recommending an antivirus scan on any recovered data
