On Ubuntu 22.04, when I try to mount my USB Stick on my file explorer (right-click on it in the side bar, then 'Mount'). A window appears with "Failed to mount USB Stick, an operation is already pending". I can't figure out what is this operation. This behavior is new. The file system on the stick is ext4.

Thank you for your help

EDIT: I still have not found a solution for this. With GParted, I can see that the data are still there on the stick, but when I try to mount it to a directory, it keeps trying forever, without finding anything.

I suggest that you create the mount point

sudo mkdir /mnt/usbdata

and find the UUID with lsblk

lsblk -e7 -o name,fstype,uuid

and edit your file /etc/fstab according to the advice in the manual page

man fstab

and add the following line (use your own file system's UUID):

UUID=4c518694-d97c-4910-bb7b-eeb6a6b73874  /mnt/usbdata  ext4  noatime 0  0

If you do not always keep the drive (USB stick with the ext4 file system) connected, you should add the boot option noauto (so noatime,noauto in field #4).

With the noauto option, you should mount the drive by the following command in a terminal window,

sudo mount /mnt/usbdata

This should start working after reboot.

The following links may help explaining/describing what to do.

  • Thank you @sudodus for the comment. I did what you suggested but sudo mount /mnt/usbdata is hanging in the terminal. Isn't there any log I can find in order to see what's going on? – Maxclac Sep 11 '23 at 06:21
  • You can run lsblk -e7 -f and cat /etc/fstab and paste the output of both commands into your original question. Please indent each line 4 spaces in order to render it as code to make it easy to read. Then write a comment to me (@sudodus) so that I will get an alert about it. - By the way, did you enter the sudo password correctly? – sudodus Sep 11 '23 at 07:49
  • Done! The password was right. @sudodus – Maxclac Sep 11 '23 at 08:17
  • I don't see anything wring in that output; 1. Please write also the output of ls -ld /mnt/usbdata (as code) and of mount | grep ext4 into your original question; 2. Did you reboot the computer after editing /etc/fstab? – sudodus Sep 11 '23 at 09:20
  • Done @sudodus
  • Yes, I rebooted the computer after having edited /etc/fstab

  • @Maxclac, Thanks for the added details. I cannot see anything wrong, and I have no advice right now. Maybe I can suggest something later on. Maybe someone else can suggest something that solves your problem ... – sudodus Sep 11 '23 at 10:05
  • Let us continue this discussion in chat. – sudodus Sep 11 '23 at 10:58
  • Did you ever try running fsck on the unmounted partition? Might be a filesystem error. – ubfan1 Oct 01 '23 at 16:01
