If your Samsung SSD has become unrecognised by the operating system and displays no accessible volumes, the likely cause is a corrupted MBR (Master Boot Record) or GPT (GUID Partition Table). These structures are essential for the operating system to interpret the SSD’s layout, file system, and boot configuration. Their corruption can render the SSD unreadable, even when the hardware itself is fully functional.

At Exeter Data Recovery, we provide advanced recovery from SSD services using forensic techniques and non-destructive processes to restore access to lost partitions, volumes, and files. Our experienced engineers work with both consumer and enterprise-grade Samsung SSDs affected by logical failures, such as partition corruption, file system breakdown, or improper formatting.

What Causes MBR/GPT Corruption on Samsung SSDs?

Partition table corruption may occur due to:

Improper shutdowns or power failures during write operations
Failed OS or firmware updates
Accidental disk management operations (deleting or converting partitions)
Malware or ransomware activity
Bad blocks affecting sector 0 (where MBR/GPT metadata is stored)
Cloning or imaging failures between different disk formats

Once corrupted, the SSD may appear in Disk Management as “Unallocated”, RAW, or not show any usable volumes at all.

Step-by-Step Technical Recovery Process

Our recovery workflow for partition-damaged Samsung SSDs focuses on safely extracting data while restoring the original disk structure, where possible.

Step 1: SSD Imaging and Write Protection

Connect the affected Samsung SSD to a write-blocked forensic imaging station
Capture a full sector-by-sector image using hardware tools such as PC-3000 SSD Edition, Atola Insight, or Deepspar
Assess the NAND and controller health via SMART data and direct chip communication
Preserve the original SSD in a read-only state to avoid any accidental overwrites

Step 2: Identification of Partition Scheme and File System

Determine if the drive uses MBR (for disks ≤2TB) or GPT (for disks >2TB or UEFI systems)
Search for lost or damaged partition entries using:
- Hex-level analysis of sector 0 (MBR) or sector 1 and GPT header/backup (GPT)
- Partition signature scanning (e.g., 0x07 for NTFS, 0x83 for Linux EXT partitions)
Confirm file system type: NTFS, exFAT, FAT32, HFS+, EXT3/4, APFS, etc.

Step 3: Rebuilding the MBR or GPT Table

For MBR Recovery:

Recreate primary and extended partition entries manually using hex editor or automated recovery tools
Validate volume boot sector (VBS) consistency and fix if necessary
Rebuild the partition alignment to match file system block size and sector layout

For GPT Recovery:

Parse the primary GPT header for partition entries
If primary GPT is corrupted:
- Use backup GPT header (stored at the end of the disk) to rebuild the table
- Recalculate CRC32 checksums and update header values
Restore alignment for UEFI boot records and logical volumes

Step 4: File System Analysis and Volume Mounting

Once partitions are restored, mount the volume read-only in a forensic environment
If the file system is partially damaged:
- Rebuild critical metadata like the Master File Table (MFT) for NTFS
- Repair volume boot sector (VBR)
- Reconstruct file allocation tables or journal entries for file systems like exFAT or HFS+
Validate file tree integrity and isolate any orphaned files or directories

Step 5: Deep Data Recovery and Carving (if metadata is unrecoverable)

For heavily damaged partitions:
- Perform file carving by scanning for known file headers/footers (e.g., JPEG, DOCX, XLSX, PST)
- Recover files from unallocated space and slack space
- Validate partial file integrity using hash checksums and internal structure analysis

Step 6: Data Validation and Secure Delivery

Perform hash verification of recovered files (MD5/SHA-1)
Review and test recovered data for usability
Transfer the recovered files to a new, healthy SSD or external drive formatted to the required file system
Provide the client with a detailed recovery summary and recovered file list

What Not to Do If Your SSD Partition Table Is Corrupted

Do NOT initialise or reformat the disk – this will overwrite existing metadata
Avoid using partition recovery software without a full sector image
Do NOT run CHKDSK, which may destroy recoverable metadata
Stop using the drive immediately and contact a professional recovery lab
