Error mounting /dev/sda2

[lwalper]

Ubuntu Version

Ubuntu 26.04 LTS

Desktop Environment (if applicable)

GNOME

Problem Description

I moved the SSDs from one Windows computer to another and now Microsoft won’t let me activate the OS due to unregistered software, no IDs and etc. It’s the OS and hardware I’ve had registered for years. Time to try Ubuntu one more time. I moved 2 SSDs, one with the OS installs and the other with user data. Both drives are formatted with NTFS. Problem is, I get the following error when I try to access the “data” drive. It works fine in Windows. What’s the problem?

What I’ve Tried

Wouldn’t know where to begin . . .

[tea-for-one]

Files (nautilus) in Ubuntu 26.04 will always mount a clean, undamaged ntfs partition

Power off the Ubuntu 26.04 PC
Boot into your Windows OS and run chkdsk on the data drive
Repair the file system if required
Safely unmount the data drive
Power off completely (not reboot)
Power on and boot into Ubuntu
Attach the data drive
Open a terminal and enter

lsblk -e 7 -o name,size,pttype,type,fstype,fsuse%,fsavail,mountpoint

Please post the output within code tags </>

It’s probably not a damaged drive. Windows likely left the NTFS drive in a messy state, so Ubuntu won’t mount it.

Let’s try this:

1. Boot into Windows.
2. Open Command Prompt as Administrator and run:

chkdsk D: /f
(Replace D: with the correct drive letter.)

3. Disable Windows Fast Startup.
4. Fully shut down Windows, then boot into Ubuntu.

If it still doesn’t work, run:

lsblk -e 7 -o name,size,pttype,type,fstype,fsuse%,fsavail,mountpoint

Post the result please and we can go from there. Hoping it will work.

OK, that worked. Chkdsk didn’t show any errors so I unmounted the drive and booted into Ubuntu. Now it mounts, no problem. Thanks! Output from the code string didn’t show much.

@lwalper

Output from the code string didn’t show much

lsblk: unknown column: mountpoint~

You have a ~ after mountpoint, hence the missing output

We all have been there…

A good starting point, when asking for help and people ask you to run commands, is to copy/paste exactly what was asked.
