Windows 11 doesn’t recognize an m.2 NVMe in a pcie slot after upgrade
Hey all,
Bought a new HP Omen 30L-1139 it has expansion slots for upto 3 m.2 SSDs. I swapped out the 2 SSDs from my old computer to the new one and everything worked as it should. I had this working for over a week, then when I upgraded to windows 11 and a new bios update, well, windows 11 doesn’t see the 2nd M.2 SSD plugged into the pcie slot.
I can go into the bios and see the ssd in the pcie slot, no way to activate it or anything like that if needed. When I go into wing, not detected at all, not under disk management, or partition either.
stumped on this one. Tried to reach out to HP; howe
- Looks I have a similar issue on my Dell T7820. The nvme in the flexbay is not available under Windows 11. I have excluded BIOS problems since the device works under windows 7.
The device manager indicates under "other devices" that there is no raid driver installed. Dell online diagnostics comes to the same conclusion and proposes a driver to install. When I do so, the drive in the flexbay is immediately accessible and works fine until shutdown. During restart a bluescreen indicates that the driver is not working and only getting back to the last restauration point allows me to run windows again in the above described state with no access to the nvme drive in the flexbay.
This is what I learned up to now.
The question for me is now, where to get a driver which is working under windows 11.
Dell will you come up with one, which is in turn passing microsoft requirements and will be included automatically in winfows update ?
For the time being windows 11 keeps telling me there is no raid driver for the nvme in a Dell T7820 flexbay.- Typo in the begining of my post: the device works under "windows 10" .
Well, after a few weeks of experimenting myself, the only way I got it to work was to remove the SSD and reinstall windows 11. When that was done and all upgrades completed I reinstalled the SSD, now it finally recognizes it. Took me allot of trial and error to get it to finally work. I even tried the disk HP sent me. It didn't work either. I had to use the window setup from Windows itself, well all that did was format one of my SSD with all my stuff on it.
Suffice to say, remove the spare ssd from your computer, upgrade it or reinstall Windows, when that's done reinstall the SSD, it should recognize it then.
Good luck!
- Thank you I appreciate your answer. I have done this as well. Windows update cannot find any appropriate driver. Dell diagnostics tells me there is no driver installed and the one they propose leads to bluescreen on reeboot. I am working with the Dell user community on the subject which seems specific to Windows 11 since rverything is working with Windows 10.
Cheers
- Looking for some help on similar issue. I have an HP Slim Desktop with 512GB m,2 primary drive and 1TB secondary HDD. I am unable to add a 4TB Crucial m.2 NVMe via PCIe or using a USB adapter on Windows 11 home edition. It shows up in the disk mgmt dashboard as unknown and when I try to initialize it, it fails to initialize it with a fatal error msg. I have tried 3 brand new Crucial m.2 NVMe drives (all 4TB) and they all fail to work on the system. Any insights on how to resolve this would be very much appreciated. HP is unable to provide meaningful assistance.
- Have a look at your motherboard manual or Google search the capacity of SSDs on it. Some will only allow upto 2GIG SSDs.
Thank you very much for your response to my email. I will look into it. In the meanwhile, I have a 8 TB SATA Seagate external USB drive that works just fine on this system for my backup however the internal 4TB m.2 NVMe is the one that seems to have some issues even using a USB enclosure. Would they behave differently between m.2 vs SATA/USB? Thanks again for your response.
Regards
