@0904, Welcome to the HP Support Community!
Thanks for reaching out about your query regarding your HP EX900 Plus!
We're thrilled to have the opportunity to assist you and provide a solution.
f your HP EX900 Plus 512GB NVMe PCIe M.2 2280 SSD was working fine and then suddenly went unrecognized by your computer, there are several steps you can take to diagnose and potentially resolve the issue:
Check Physical Connections:
- Ensure that the SSD is properly seated in the M.2 slot. Sometimes reseating the SSD can resolve connection issues.
- Make sure that the screws securing the SSD in place are not too tight, as this can sometimes cause issues with connection.
BIOS Settings:
- Check your computer’s BIOS settings to ensure that the M.2 slot is enabled.
- Look under the boot or storage settings in BIOS to see if the SSD is detected.
Update BIOS and Drivers:
- Ensure that you have the latest BIOS update for your motherboard.
- Update your motherboard chipset drivers as well.
Check Disk Management:
- Go to Windows Disk Management (Right-click on Start > Disk Management) to see if the SSD is listed. If it is listed but unallocated, you may need to format or partition the drive.
Device Manager:
- Check the Device Manager (Right-click on Start > Device Manager) to see if the SSD appears under Disk Drives.
- Make sure there are no exclamation marks or errors listed.
Swap Slots:
- If available, try installing the SSD into a different M.2 slot on the motherboard to rule out slot issues.
Test on Another System:
- If possible, test the SSD in another computer to verify if the issue is with the SSD or your original system.
Firmware Update:
- Check for any firmware updates for the HP EX900 Plus SSD.
Inspect for Damage:
- Physically inspect the SSD for any visible signs of damage or burning.
Hope this helps!
Take care, and have an amazing day!
