Assessing the Failure Mode
Before attempting any recovery, it is crucial to determine whether the issue is logical (software-related) or physical. A Blue Screen of Death (BSOD) triggered during an update typically indicates that the operating system attempted to write critical system files to the NVMe drive but encountered I/O errors or driver incompatibilities. If the drive makes clicking noises or is not detected in the BIOS/UEFI at all, the controller may have failed, requiring professional service. However, if the drive spins up or lights up but shows no partitions in Windows Explorer, the file system table is likely corrupted.
Start by checking the Device Manager on a healthy PC. Connect the NVMe SSD via a USB enclosure or SATA adapter if supported. If the drive appears under "Disk Drives" but with a yellow exclamation mark, there is a driver conflict. Right-click the device and select "Update Driver." Often, installing the latest manufacturer-specific NVMe drivers resolves the communication barrier between the OS and the storage controller.
Connecting the Drive for Access
The most effective way to retrieve data from a non-bootable NVMe drive is to treat it as external storage. You will need a compatible NVMe to USB adapter or an internal PCIe slot on a secondary workstation. Ensure the target computer has sufficient power delivery, as NVMe drives can draw significant current during initialization. Once connected, do not attempt to format the drive when prompted by Windows, as this will overwrite potential recoverable data.
If the drive is not recognized in File Explorer, open Disk Management by pressing Win + X and selecting "Disk Management." Look for the disk listed with its capacity. If it shows as "Unallocated," the partition table is damaged. If it shows as "RAW," the file system structure is unreadable. In both cases, specialized software is required to read the raw sectors and extract files. Avoid running chkdsk immediately, as it may attempt to fix structures in a way that destroys data integrity.
Using Data Recovery Software
When standard tools fail to mount the volume, dedicated data recovery software can scan the raw sectors for recognizable file headers. Tools like Recuva, TestDisk, or commercial suites such as R-Studio are designed to reconstruct file systems without writing new data to the source drive. Select the NVMe drive carefully to avoid scanning the wrong device. Configure the software to perform a deep scan, which searches for known file signatures like JPEGs, PDFs, and DOCX files regardless of the directory structure.
Once the scan completes, preview the found files to verify their integrity. Save the recovered data to a different physical drive, never back to the NVMe SSD itself. This prevents overwriting other potentially recoverable sectors. If the drive is severely degraded, consider creating a sector-by-sector image first using a tool like ddrescue on Linux, then run recovery software against the image file for safer analysis.
Preventing Future Update Failures
To avoid recurrence, ensure your system has adequate free space before initiating major Windows updates. NVMe drives perform best when they have spare blocks available for wear leveling and garbage collection. Check your drive health using manufacturer utilities like Samsung Magician or WD Dashboard to verify the endurance level. Additionally, create a system restore point or full disk image before applying large feature updates.

If you encounter specific error codes during the update process, such as 0x80070643, these often indicate installation failures rather than data loss. Understanding these errors can help you distinguish between a bad update and a failing drive. Refer to Windows 10 Pro 64-bit Installation Error: One Update Constantly Fails (Error 0x80070643), No KB Update Number for troubleshooting steps related to persistent update errors.
Frequently Asked Questions
Can I use Command Prompt to recover deleted files?
No, Command Prompt cannot recover deleted files once the pointer to the data is removed. It can only repair file system structures using commands like chkdsk, which may further corrupt data if used improperly on a failing drive. Use dedicated graphical recovery tools instead.
Is it safe to run CHKDSK on a failing NVMe drive?
Running chkdsk on a drive with physical errors or severe corruption can sometimes worsen the situation by forcing the drive to rewrite damaged sectors. It is safer to clone the drive first or use read-only recovery software to extract your data before attempting any repairs.
What should I do if the NVMe drive is not detected in BIOS?
If the drive is invisible in BIOS, the issue is likely hardware-related, such as a loose connection or dead controller. Try reseating the drive in a different M.2 slot or using a different USB adapter. If it remains undetected, professional data recovery services may be required to bypass the controller.
Does Windows Update automatically delete my personal files?
Windows Updates generally do not delete personal files like documents, photos, or videos. They primarily affect system files, drivers, and installed applications. However, if the update causes a BSOD and subsequent file system corruption, some data may become inaccessible until repaired.
How long does a deep scan of an NVMe drive take?
A deep scan duration depends on the drive's capacity and speed. For a 1TB NVMe drive, a comprehensive signature-based scan can take anywhere from 30 minutes to several hours. Slower USB adapters may significantly extend this time due to bandwidth limitations.
