[SOLVED] Second SSD doesn't show in dual boot system (Ubuntu 24.04, Windows 11)

Hi,
I set up my new fw 16 laptop with a dual boot system. I use Windows 11 Pro and Ubuntu 24.04.

Both operating systems boot from the same ssd that has two partitions (one for windows and one for ubuntu). So the second ssd is just for storing files, videos, documents and stuff.

When I open the Ubuntu Program “Laufwerke” (german for “disks”), it shows both ssd’s. The 500GB ssd is the one that is used for booting both operating systems, the 1TB ssd is the one just for storing data.

However, in my Ubuntu File Explorer, I don’t see the 1TB ssd. So I can’t access it from Ubuntu. It only shows the 100Gb partition of the 500GB ssd that is used for booting Ubuntu and the other 392GB partition of the ssd which runs windows.

Has anyone got an idea, on how I can access the 1TB ssd via the file explorer in Ubuntu?

On windows, everything works just fine.

Your 1TB SSD is not mounted in Ubuntu. Ubuntu knows it’s there but cannot read the contents. It says “unknown” and it’s not mounted. Click on partition 2 in Disks, what happens? What does it say? Can you mount it? I don’t think you can, because it’s unknown.

It’s Windows 11, so it should be NTFS. Ubuntu should have the ntfs-3g package which can work with NTFS and it should be installed by default. The fact that it doesn’t know anything about that drive when it should be able to read NTFS is a mystery though. Do you have file encryption on your Windows drive? BitLocker?

I’m out of my element with Windows and BitLocker, so I hope someone else chimes in here.

Hi, thanks for your reply!
This it what the 1TB ssd says, when I click on the partition 2:

Yep, in Windows 11, the disc is formatted in NTFS. I checked, that BitLocker is turned off for the 1TB SSD, so it should be visible and readable for Ubuntu. My 500GB SSD is also visible and it has the same configuration (also NTFS, Bitlocker also deactivated).

This is what the different partitions of the 500GB SSD look like:

I could resolve the issue :smiley:

I just formatted the partition 2 of the 1TB SSD in Ubuntu to NTFS. Now the SSD is shown in my Ubuntu File explorer and I can also use it on Windows - exactly how I want it to work!

Maybe it was unformatted then? I assumed you had Windows installed on it.

It has been formatted to NTFS before and I were able to access it under windows. I don’t know what has been the issue.
