I can't open external drives in Dolphin

[carpet]

Out of the blue, I started getting this message in Dolphin while trying to use my external drives (tried one of them on Windows, it works there):

An error occurred while accessing '...', the system responded: The requested operation has failed: Error mounting /... at /...: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error

Looked at these topics: 1, 2

Went here
and then here

From my terminal:

sudo mount -t  ntfs /dev/sda1 /run/media/...                                                             
fuse: failed to access mountpoint /run/media/...: No such file or directory
sudo mount -t ntfs3 /dev/sda1 /run/media/...
/run/media/...: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error.
       dmesg(1) may have more information after failed mount system call.

Did I mess up the command syntax? I wish the Fine Manual had several concrete examples for dumb-dumbs.
Btw, why is this happening all of a sudden?

I’m seeing a few similar posts on this theme.

I assume you created the folder before creating the mount point:

sudo mkdir /run/media/myfolder
sudo mount -t  ntfs /dev/sda1 /run/media/myfolder

Are the respective fuse and ntfs-3g packages installed?
Have you installed the latest Manjaro update?

The questions could be endless, so I’ll stop here. Cheers.

Now there’s an explanation for a dumb-dumb.
