Immediate Safety Steps
The most critical step in this scenario is to stop using the affected computer immediately. If the drive is still installed internally, powering down the system prevents further writes to the storage medium. Every time the operating system attempts to read or write to a failing drive, it increases the risk of permanent data loss. Do not attempt to run disk repair utilities like chkdsk on the primary drive while it is still connected as the boot volume, as these tools can overwrite critical file system structures.
Physical Connection Methods
To access your data, you must remove the NVMe drive from the failed machine and connect it to a working computer. There are two primary ways to achieve this connection, each with specific technical considerations for NVMe protocols.
Using a USB-to-NVMe Enclosure
This is the safest and most recommended approach for most users. You will need a USB enclosure that supports the PCIe/NVMe protocol (often labeled as M.2 NVMe). Standard SATA enclosures will not work. Once you have the correct enclosure:
- Power off the working computer and disconnect all peripherals.
- Open the case and insert the NVMe drive into the enclosure, ensuring the connector pins align correctly.
- Secure the drive with the provided screw or clip mechanism.
- Connect the enclosure to a USB 3.0 or higher port on the working computer.
This method isolates the drive from the original motherboard’s potential firmware conflicts and presents it as a standard external USB mass storage device.
Daisy-Chaining via Another M.2 Slot
If your working computer has an available M.2 slot on the motherboard, you can install the recovered drive directly as a secondary internal drive. This often provides faster transfer speeds than USB enclosures because it utilizes the direct PCIe lane connection rather than the USB bridge.
- Identify an unused M.2 slot on the motherboard.
- Check the manual to ensure the slot supports the length of your NVMe drive (typically 2280).
- Install the drive and secure it with the standoff screw.
- Boot the computer and enter the BIOS/UEFI to verify the drive is detected.
Note that some older motherboards may not support booting from multiple NVMe drives simultaneously without specific BIOS updates, but they should still recognize the second drive for data access once Windows loads.
Accessing the Data
Once the drive is connected to a functional system, open File Explorer and check if the drive appears under "This PC." It may appear as a new drive letter (e.g., D: or E:).
Handling Permission Errors
You will likely encounter permission denied errors when trying to access folders in C:\Users\YourOldUsername. To resolve this:
- Right-click the folder and select Properties.
- Navigate to the Security tab.
- Click Advanced and then change the owner from the old user account to your current administrator account.
- Check the box to replace all child object permissions and apply the changes.
This process grants your current Windows installation ownership of the files, allowing you to copy them to your new drive. Be patient, as this operation can take several minutes depending on the number of files.
Using Data Recovery Software
If the drive does not appear in File Explorer or shows as RAW format, the file system table may be corrupted. In this case, use professional data recovery software such as Recuva, EaseUS Data Recovery, or R-Studio. These tools can scan the raw sectors of the NVMe drive and reconstruct files based on their signatures rather than relying on the file system index.
Preventing Future Update Issues
After successfully recovering your data, it is essential to address the root cause of the failure. Windows 10 updates occasionally conflict with specific NVMe controller drivers or power management settings. Before updating again, ensure your motherboard BIOS is updated to the latest version, which often includes fixes for NVMe compatibility. Additionally, consider creating a system image backup using Windows Backup or third-party tools before applying major feature updates.

Frequently Asked Questions
Can I use a SATA SSD adapter for my NVMe drive?
No, SATA adapters are physically and electrically incompatible with NVMe drives. NVMe uses the PCIe interface, while SATA uses a different protocol. Using the wrong adapter will not damage the drive but will simply fail to connect, so always ensure you purchase an enclosure specifically labeled for NVMe/M.2 PCIe.
What if the drive is not detected in BIOS?
If the drive is not detected in BIOS, the issue may be physical. Try reseating the drive in the enclosure or testing it in a different USB port. If it still fails, the drive’s controller may have been damaged during the update crash. At this point, professional data recovery services that specialize in chip-off recovery may be necessary.
Will recovering data delete my old Windows installation?
No, accessing the drive as a secondary storage device does not erase any data. You are only reading from the drive. However, if you choose to format the drive to fix errors, all data will be lost. Always prioritize copying your important files before attempting any formatting or repair operations.
Is it safe to run chkdsk on the recovered drive?
It is generally not recommended to run chkdsk unless you have already copied your important data elsewhere. chkdsk attempts to fix file system errors, which can sometimes result in data loss if the corruption is severe. Use it only as a last resort after backing up accessible files.
How do I know if my NVMe drive is encrypted?
If the drive was encrypted with BitLocker, you will need the recovery key to access the data. Without the key, the data is inaccessible even if the drive is physically healthy. Check your Microsoft Account online or printouts from your initial setup for the 48-digit recovery key.
