Can no longer automount exfat or ntfs partitions

Desktop Environments Plasma
1

Today I tried to mount my Ventoy USB and it will not mount in EndeavourOS with the LTS or Arch Kernel.

  • I uninstalled and reinstalled Ventoy from the AUR and that made no difference.
  • I manually installed Ventoy from the Ventoy website and that made no difference.
  • The error given in Plasma in the disk popup is Could not mount this device

However, when I boot into Windows 10 the very same Ventoy USB disk is easily mounted and works as expected.

There are a couple of recent comments on the AUR page for Ventoy which state the libgcrypt package is necessary, but that’s already installed on my system.

Is anyone having the same problem? Is there a solution?

As a followup comment, it seems I can’t mount any exfat or ntfs drives, even though all the pertinent packages from libguestfs are installed, even though I’ve been able to before today. Possibly a recent update caused this?

Cannot see what libguestfs has to do with anything.

  • Which DE?
  • Can you boot from it?

DE is Plasma. I can boot from the Ventoy disk.

However, since I reformatted the USB and reinstalled Ventoy to try to make it work there are no ISOs on the Ventoy partition (exfat format) where the ISOs are stored. And for some reason exfat partitions won’t open any more on my computer.

I will assume you have rebooted? (and are aware that kernel upgrades will break modules dynamic loading)

6

I’ve rebooted many times. I’m fairly certain some upgrade broke something, which is why I was asking if anyone else had the same problem. I don’t know which upgrade did it. I know that the kernels are updated often so maybe this will work itself out soon.

7

No issue here, which is why I asked about if you’d rebooted. I copied POP_OS iso this morning to my Ventoy.

8

Which kernel version are you running?

9

Latest (not LTS)

10

/var/log/pacman.log is text and can show you what was installed and when.

You could try changing mirrors and do a pacman -Syu

11

Nothing really jumps out as out of the ordinary in the pacman.log. I changed mirrows and ran an update but there’s no change. Is there anything I should look for specifically?

12

Are you able to use other USB sticks? I’ve had them die before.

13

So your problem is not “ventoy”, it’s mounting some filesystems in general? Maybe you could change the title, some people may say that they don’t use ventoy and won’t read your post.

Are you able to mount ext4 or btrfs drives?

14

Thanks, I took your advice and renamed the title. The problem seems to be with external drives. My internal SSD is ext4 and I have no problem with that.

External drives formatted to exfat and nfts will not mount, and this is a recent development. Fat32/16 works fine. I really don’t have any other drives/USB sticks in any other format.

15

The USB sticks themselves are fine. If I reformat them to anything other than exfat or ntfs they work as expected.

16

If they’re fine, then something must be wrong with your kernel which would provide support for the filesystems.

17

Would reinstalling the kernel be helpful?

Edit: I ran sudo reinstall-kernels and it didn’t change anything.

I’ve made an interesting discovery. I believe the difficulty I’ve been having has to do with a USB A to C adapter that I have been using. When I forego that USB A to C adapter and plug the USB stick and SSD directly into a media hub they automount as expected.

When using the USB A to C adapter I can manually mount those exfat and ntfs in Konsole.

Perhaps it’s time to purchase a different adapter.

Thanks for your help!
