Lenovo IdeaPad Pro 5 Gen 9 AMD Ryzen 7 8845HS SSD Not Detected Fix Windows 11

The SSD in your Lenovo IdeaPad Pro 5 Gen 9 AMD Ryzen 7 8845HS is not appearing in File Explorer or Windows cannot find an operating system, indicating the SSD is not being detected by Windows or the BIOS. NVMe driver updates and physical SSD connection checks resolve most SSD detection failures on the IdeaPad Pro 5 Gen 9 AMD.

This guide covers NVMe driver updates, Disk Management, physical SSD seating, and BIOS storage settings for the Lenovo IdeaPad Pro 5 Gen 9 AMD Ryzen 7 8845HS in Windows 11.

“IdeaPad Pro 5 Gen 9 second SSD not detected after installation. Lenovo Vantage had AMD NVMe driver update. After installing, second drive appeared in Disk Management. Initialized and partitioned it from there.” – Haziq, IT consultant from Selangor

Why SSD Is Not Detected on IdeaPad Pro 5 Gen 9 AMD

SSD not appearing in Windows has different causes depending on whether it is the primary OS drive or a secondary storage drive. For a second SSD added to an empty M.2 slot, the drive is physically present but may need initialization in Disk Management before appearing in File Explorer. For any NVMe SSD not appearing in Device Manager, the AMD NVMe controller driver or the physical M.2 connection requires attention. A completely undetected primary SSD (no boot, no OS) indicates a hardware or physical connection failure.

• New second SSD installed but not initialized – appears in Disk Management as unallocated space
• AMD NVMe controller driver missing causing PCIe NVMe SSD not enumerated in Device Manager
• M.2 SSD not fully seated – one edge lifted from M.2 slot connector
• BIOS showing SSD as disabled or in compatibility mode for different NVMe protocol version

Fix 1 – Check Disk Management for Uninitialized SSD

Press Windows + X and select Disk Management. Look for a disk listed as Unknown or Not Initialized (usually Disk 1 or Disk 2 if a second drive was added). Right-click the uninitialized disk and select Initialize Disk. Choose GPT partition style. After initialization, right-click the unallocated space and select New Simple Volume. Follow the wizard to create an NTFS partition. The new SSD volume appears in File Explorer with a drive letter. This fix applies when the SSD is physically connected and detected by the hardware but not yet configured for use in Windows.

Fix 2 – Update AMD NVMe Driver via Lenovo Vantage

Open Lenovo Vantage and go to System Update. Look for AMD NVMe Driver or AMD StoreMI driver updates. Install and restart. The AMD NVMe controller driver governs how the Ryzen 7 8845HS PCIe lanes communicate with connected NVMe SSDs. An outdated or missing AMD NVMe driver causes connected SSDs to not enumerate in Device Manager, appearing entirely absent from the system until the correct driver is installed. Updated AMD NVMe drivers also improve Gen 4 SSD detection reliability during cold boot.

Reseat M.2 SSD Physically

Power off the IdeaPad Pro 5 Gen 9 AMD completely. Remove the bottom panel screws and lift the panel. Locate the M.2 SSD. The SSD should be flat and secured with one screw at the far end. If the SSD is lifting at an angle from the connector, it is not fully seated. Remove the retention screw, press the SSD flat into the M.2 connector, and replace the screw firmly. Partial M.2 contact (only some lanes connected) causes the SSD to be intermittently detected or detected with reduced speed rather than not at all.

Fix 3 – Check BIOS Storage Configuration

Restart and press F2 for BIOS. Go to Configuration – Storage – Storage Controller mode. Ensure NVMe mode is selected (not AHCI for the M.2 slot). Also check that the specific M.2 slot with the undetected SSD is enabled. Some IdeaPad Pro 5 Gen 9 BIOS versions list individual M.2 slots that can be independently enabled or disabled. If an M.2 slot is disabled in BIOS, the connected SSD is completely invisible to Windows regardless of driver state.

Fix 4 – Update BIOS for NVMe Compatibility

Go to Lenovo Vantage System Update and install BIOS updates for the IdeaPad Pro 5 Gen 9 AMD. BIOS updates include AMD AGESA firmware that manages PCIe lane initialization and NVMe device enumeration during POST. Updated AGESA improves compatibility with newer NVMe SSD firmware versions and resolves specific Gen 4 SSD detection failures during cold boot that result in Windows reporting no boot device found on the primary SSD.

Frequently Asked Questions

Why is SSD not detected on Lenovo IdeaPad Pro 5 Gen 9 AMD Ryzen 7 8845HS?

New SSD uninitialized (check Disk Management), NVMe driver missing (update via Lenovo Vantage), or M.2 SSD not fully seated physically.

How do I fix SSD not showing in Windows on Lenovo IdeaPad Pro 5 Gen 9?

Disk Management for uninitialized check, AMD NVMe driver update via Lenovo Vantage, physical M.2 reseat, BIOS M.2 slot enable check.

What SSD does Lenovo IdeaPad Pro 5 Gen 9 AMD Ryzen 7 8845HS have?

M.2 2280 PCIe Gen 4 NVMe – Samsung or WD factory SSD. One or two M.2 slots depending on configuration.

Can I add a second SSD to Lenovo IdeaPad Pro 5 Gen 9 AMD?

Some configurations have a second empty M.2 slot. Remove bottom panel to check. Initialize in Disk Management after installation.

Conclusion

Lenovo IdeaPad Pro 5 Gen 9 AMD Ryzen 7 8845HS SSD not detected in Windows 11 is resolved by checking Disk Management for uninitialized status on newly added drives, updating AMD NVMe driver via Lenovo Vantage, and physically reseating the M.2 SSD if partially disconnected. BIOS M.2 slot enable setting and AGESA firmware update from Lenovo Vantage address boot-time SSD enumeration failures that cause Windows to report no bootable device on the primary NVMe SSD.
