25 Years of Expertise in Advanced SSD Data Recovery
When your Asus laptop’s M.2 SSD fails immediately after a Windows upgrade and you discover your data has disappeared, the issue is typically linked to logical corruption, partition table changes, or SSD firmware malfunction. At Coventry Data Recovery, we specialise in complex SSD failures involving M.2 NVMe and SATA drives from Asus laptops, offering a full suite of forensic-level data recovery services.
💻 Common Issue: SSD Not Showing Data After Windows Upgrade
Upgrading or reinstalling Windows can alter or corrupt the partition structure of the SSD, particularly with M.2 NVMe drives. In some cases, the upgrade routine can:
- Overwrite the existing partition table (GPT or MBR)
- Create new system partitions and wipe user partitions
- Render the drive unreadable due to TRIM operations
- Cause firmware-level lock-up or corruption in SSD controller
This results in the appearance that the drive is functioning, but the data is gone or unreadable.
🔧 Step-by-Step SSD Recovery Process (Asus M.2 Drive)
1. Drive Isolation & Write Protection
- The SSD is safely removed from the laptop and connected to a dedicated write-blocked forensic imaging station to prevent accidental TRIM or overwrites.
- The system checks for controller-level faults and verifies NAND accessibility.
2. Low-Level Imaging of the SSD
- Using hardware-based recovery tools such as PC-3000 SSD Edition, a full sector-by-sector image is created.
- Even deleted or overwritten areas are copied using raw NAND-level access, bypassing the logical file system.
3. Partition Structure Analysis
- We reconstruct the original GPT/MBR layout by:
- Analysing file system signatures (NTFS/FAT/exFAT)
- Scanning unallocated sectors for lost partition metadata
- Identifying the Windows upgrade overwrite region
4. File System Repair & Data Carving
- Corrupted NTFS or exFAT partitions are repaired using safe, read-only methods.
- Where file system repair is not possible, deep file carving is used to extract files based on header and footer signatures (e.g. JPG, DOCX, MP4).
- Metadata is reconstructed to preserve filenames and folder structure wherever possible.
5. Verification & Recovery Output
- Recovered data is validated for integrity.
- All files are returned on a new portable drive, and we provide a recovery report detailing what was recovered.

🧰 SSD Recovery Scenarios We Handle
| Issue | Technical Recovery Summary |
|---|---|
| Partition table overwritten after OS upgrade | GPT header/footer reconstruction using backup sectors and forensic heuristics |
| TRIM command erased user data | NAND image recovery via chip-off or controller bypass, partial data reconstruction |
| Firmware crash post-install | Controller reinitialisation and microcode stabilisation using PC-3000 SSD suite |
| Missing files/folders | Deep logical scan and file carving from slack/unallocated space |
| Read-only lock due to SMART failure | Firmware bypass to allow read-level access only |
| Unresponsive NVMe SSD | Voltage regulation check, thermal controller diagnostics, interposer board imaging |

📞 Get Help Recovering Data From Your SSD
If your Asus M.2 SSD stopped working after a Windows update and critical data is no longer visible, do not attempt system restore or reinstallation. This may permanently overwrite sectors and reduce the chances of recovery.
