HELP! M.2 NVME drive not showing up in disk management.

Posted by Daanjansen@reddit | buildapc | View on Reddit | 141 comments

Hi, everyone

I need some help figuring out why my new m.2 ssd is not showing up in disk management First of all heres my parts list: https://pcpartpicker.com/list/qBjHXb

So I bought a second m.2 nvme drive (Intel 660p 1TB). After having installed it in the M2M slot of my motherboard the drive shows up in the bios, device manager, in the properties of my C:/ drive and even CPUID Hardware monitor detects the drive as seen in the screenshots provided. Despite this I cannot manage to get the drive to show up in disk management so I can assign a drive letter to it and have it show in the file explorer.

Ive been at it all day trying out fixes of people with similar problems but no luck yet. This is what ive tried so far:
- Reseating the drive
- Installing the correct drivers directly from intel.
- Deleting the Standard AHCI 1.0 Serial ATA-controller drivers
- Deleting, reinstalling and updating all disk related drivers.
- Run the hardware and devices troubleshooter
- Ive tried 3rd party software, ("Minitool Partition Wizard" which couldn't detect the drive and "EaseUS partition master" which did detect the drive but could only scan it for files.)
- Diskpart
- Disabling SATA port 4/5 in bios
- Enabling and disabling RAID
- Disabling CSM and fast boot settings in BIOS

I am probably still missing a few fixes that ive already tried. I have basicly tried everything I was able to find and cannot find any new posts with proposals of fixes I havent already done.

The only thing I can think of that I havent done is switch the Intel drive with the Crucial one to see if the M2A slot does work. But because of the hassle removing the CPU cooler to access the slot I would rather do that as a last resort.

In the imgur link below theres some pictures of the diskmanager, devicemanager etc. (Sorry for the OS language not being English I hope it isnt too much of a problem) https://imgur.com/a/Z4mcFEp

If theres any additional info needed I would be happy to provide it. I hope we can find a fix and possibly help others experiencing the same problem.

Edit: Fixed a formatting error and added attempted fixes.

Edit2: So after a chat with Intel support I did a low level format using KillDisk which fixed the issue.

I'm extremely late to the party but my drive was recognized in BIOS and in Device Manager but was not showing up in Disk Management, thus, it wasn't functional. In Control Panel, follow the path Control Panel\System and Security\Storage Spaces\Create a storage pool and it showed my unformatted drives. I selected Simple formatting and typed my max GBs in (my drive showed 930 GB available so I put 930 GB) and the drive then showed up in Disk Management. I hope this helps someone. Good luck

You saved me.

For any on win11 the setting slightly moved. It's in System > Storage > Disks and Volumes.

Should be an option to create a volume, you can just choose basic drive and let all the settings be default unless you know what you're doing.

Glad it helped! Thanks for the win11 update!

Posting because this thread helped me solve a similar issue. When I went to disk management, I originally could not see my new SSD (it showed up in Bios and Device Manager) until I switched the view from “Volume List” to “Graphical View”. Under volume the drive would not show up because it did not have any data on it, but under Graphical View it showed up and I could initialize it

[-]

DJHeadshotHunter@reddit

For anyone who may be reading this thread years later (like me) I want to try and help you if nothing else has worked. One thing you might also want to try is your PSU. I spent probably 10 hours trying every suggestion on Reddit but my fix was simple...... the power supply unit (PSU). I thought it was my motherboard socket at the end of the day but it wasn't. My PSU was failing.... and not giving sufficient power to that NVME drive slot for some reason but yet my other NVME slots worked totally fine. So If all else fails on this list try upgrading or getting a new PSU. I went from a failing 750 watt PSU to a new 1000 watt PSU. And just like that my NVME drive started working flawlessly again. So I hope this might help anyone who might still be trying to figure it out. Give it a shot, and good luck on your troubleshooting!!

How to Fix the Issue: NVMe M.2 Drive Shows in BIOS but Not in Windows Disk Management

If your BIOS detects the NVMe M.2 SSD but Windows Disk Management does not, here are the most common causes and solutions.

🔧 1. Check if the drive appears in Device Manager Sometimes Windows sees the drive, but Disk Management does not.

Open Device Manager
Expand Disk drives or Storage controllers
Look for your NVMe SSD

If it appears here but not in Disk Management, the drive may: - Not be initialized - Have an unsupported or corrupted partition table (e.g., Linux partitions)

2. Check the drive using DiskPart 1. Open Command Prompt as Administrator 2. Type: diskpart list disk

If the NVMe drive appears → Windows detects it, but it may need initialization or cleaning.
If it does NOT appear → Windows is not communicating with the drive (BIOS settings, compatibility, or drivers).

If DiskPart sees the drive but Disk Management does not The drive may have a corrupted or incompatible partition table.

You can clean it ( this erases all data):

select disk X clean exit

After this, Disk Management should prompt you to initialize the drive (GPT recommended).

Check BIOS settings Some M.2 slots share lanes with SATA ports or require specific settings.

Verify in BIOS:

PCIe/NVMe mode is enabled
CSM (Compatibility Support Module) is disabled
SATA mode is set to AHCI
The correct M.2 slot is enabled
No SATA ports are disabled due to lane sharing

🔌 5. Check compatibility Some motherboards support only:

SATA M.2 drives or
PCIe NVMe drives

If your slot supports only SATA, an NVMe drive may show in BIOS but not in Windows.

6. Update drivers Updating these can help:

Chipset drivers (especially on AMD systems)
NVMe controller drivers
Windows updates

If you want, I can also prepare a shorter “quick guide” version or help you translate more technical content.

Exciting_Artichoke_4@reddit

If it helps anyone, I have an NVMe M2 drive that initially didn't appear in Disk Manager. Some pending Windows 11 updates were installed, and after restarting, it magically appeared.

[-]

Emelius@reddit

I had a very similar issue on Windows 11. I fixed it in the most peculiar way. When I went to Disk Management it wasn't showing up, but in the search results when I searched for "disk...", I saw an option pop up called "Manage Disk & Volumes". I'm guessing this is the new Windows 11 version of the older Disk management tool.

I saw that my drive was being recognized there, so I clicked to format it, then it threw up an error saying essentially "You can't format a read-only drive", but the funny thing is once that popped up, i saw that the drive was now appearing in the older control panel Disk Management tool. From there, I was able to properly format it.

Dunno if people are getting some weird ass Windows 11 funkiness with this issue, but in my case it was.

[-]

Grouchy-Kick6070@reddit

You saved my day, it works for me, that's crazy

[-]

GG_Z@reddit

Sorry for the notification but searching manage disk and volumes is what worked for me. Its the only place I could see the drive to format it

[-]

vapocalypse52@reddit

I had to reseat a drive because I didn't push it enough in the slot. Some slots are very tight and need a bit more strength to fully get in.

Does it appear in the BIOS?

[-]

Daanjansen@reddit (OP)

Yes it does appear in the BIOS I have also tried reseating it aswell.

Important_Swing_9816@reddit

I bought an external M.2 SSD to USB adapter box from some Chinese website for $8, plugged in the dead drives that never showed up in disk management or in BIOS, and then they appeared, all usable.

[-]

Shot_Bass@reddit

So the solution at the top works but for me, it isn’t traditional for a simple m.2

When I went into disk management I couldn’t see the unallocated m.2 device because i needed to scroll down. For some reason the scroll wheel doesn’t work so just try and check for a scroll wheel bar and click it down. Maybe you will see your unallocated device and you can go from there.

Try that out let me know

[-]

Hairy_Day_357@reddit

Full STOP:: This is an easy fix-

Right Click Start/Windows>Disk Management> Scroll to the drive and it likely says "Unassigned"> just assign a volume to it and click format, assign drive letter and youre good.

GhostBandit86@reddit

So a year on from the deleted comment that saved many people… drag the window down on disk management and it’s probably sat there at the bottom. Mouse scroll doesn’t work. I’m a moron too

[-]

SnarKsByte@reddit

Wow. This was it. Good on you. Had to Drag the window bigger and there it is.

[-]

Suphinx@reddit

Dude your comment should be the top comment. I initially created the storage pool which worked, but knew there had to be an actual issue for why it wasn’t showing and this was 100% it. You have to manually drag the window to see more and allocate the volume which makes it show in the disk management now. Thank you for this!!!

[-]

Financial-File-5387@reddit

For those still wondering. I went through all of this and it was really the simplest solution I could have ever found lol. Make sure on the bottom portion of the disk manager that you scroll down XD. Worked for me.

Drewski_sG@reddit

Holly shit literally just had to drag the window down.

this comment saved me - but super weird - it took sometime for it to show as "unallocated space" - probably 10-15 mins after I seated it, did it finally show up - was making me go crazy

What part are you stuck on, do you see the drive in BIOS?

[-]

Dusty_Jangles@reddit

I actually just got it lol. Went into the old disk management program and it was there, just assigned it a volume as another comment said, formatted it and it was good to go! Thanks for replying though, appreciate it! And hopefully these help someone else!

Endeyslayer@reddit

smh just had to do the same

[-]

fallouthirteen@reddit

And don't be fooled by its bad UI. Like I just had this problem now, read your comment, checked and thought it wasn't it. I thought I did scroll down (I used the mouse wheel in that box). Ended up going all the way to diskpart and using list disk to see that it knew I had the disk. Then went back to disk management and saw "wait, that grey part on the side isn't at the "bottom" bottom). Dragged on that side part and there it was.

WHY HAVE 1 PANEL OF THE WINDOW NOT REACT TO SCROLL WHEEL? Top part reacts to scroll wheel when the cursor is in that panel, just not the bottom part.

I tried installing KillDisk but it doesn't detect my new SSD. It just shows my C: drive. The new SSD is recognized in BIOS but nowhere in windows, device manager, disk manager, etc. does it show up. What do I do? I've spent over an hour looking up every guide I could find and nothing is working.

[-]

eliasrmf@reddit

Which type? Nvme? My old system had one slot for Sata and another for Nvme. Need to check whether this could be the case. I've been able to consistently see my SSD on bios and dvc mgmt, the only missing was on Windows. So I've reached this thread about KillDisk and it found my device while other tools couldn't. You need to check which type of M2 your Mobo support, which type you bought and put the pieces together.

[-]

roman1177@reddit

Turns out the reason it wasn't showing is because my motherboard won't let me use a second SSD because my CPU is 10th gen and not 11th gen. So I gotta buy a new CPU, yay.

[-]

aNINETIEZkid@reddit

instead of upgrading from 10th to 11th gen cpu to use the second m2 port maybe you could add a PCIe ssd adapter and run it from there.

[-]

eliasrmf@reddit

CPU should not be the reason for an HDD or SSD not being recognized. This sounds odd. Unless, as I've asked before you're trying to get 2 Nvme SSD in the same Mobo, that may require a latest version Mobo.

[-]

roman1177@reddit

My mobo is a B560 DS3H AC-Y1. Prebuilt PC, came with a 10th gen CPU. The second SSD port is unusable unless I upgrade it to an 11th gen.

[-]

aNINETIEZkid@reddit

damn this must be what is screwing with me and my b560 pro4 when trying a 2nd ssd in the top port.. thanks :/ I'll try the 3rd port and maybe that will work

[-]

HAL-Over-9001@reddit

Old thread, but I'm having the same issue. My 5800x is dual M.2 compatible, and both NVME slots on my mobo are M.2 compatible. I'm gonna try using Killdisk like they mentioned in this thread and report back.

[-]

Popular_Many4815@reddit

I had come up with a different solution. Control Panel>System and Security>Storage Spaces. If you can see your SSD in Storage Spaces but not in Disk Management, delete it. Then click "Create a new pool and storage space" and use the settings required for your SSD (you may have to use no resiliency).

This is just what worked for me. c:

[-]

Unforgiven17@reddit

By chance did you figure out a solution for this? I see this was 8 months ago but I just bought a new gigabyte motherboard and am having a very similar issue.

[-]

Daanjansen@reddit (OP)

Sorry for the late response. If you are still looking for a fix, this is what I did: I ended up chatting with Intel support, they suggested I do a low level format of the drive using a program named KillDisk. After the format it showed up fine in diskmanagement.

Hope it helps gif

[-]

mr_rasfar@reddit

Had new kingston ssd that showed in device manager, but not in disk management. After formating with KillDisk issue was solved. Thanks!

[-]

Descrete@reddit

FOR ANYONE THAT HAS THIS ISSUE. Use KillDisk to delete the contents of the drive that's not showing up in Disk Management. After everything is deleted you should be able to format it normally. Just worked for me <3

[-]

cpinkfloy4@reddit

FOR ANYONE *STILL* HAVING ISSUES im an idiot, and found that if i go into Computer Management -> disk Management then click on the drive from here. Format the drive (if it is a new drive) then assign it a drive letter, it will now show up in your Folder explorer.
