I got a notification that I cannot access my USB flash drive both 32GB and 64GB. Before it will auto-detect after being inserted. I am new to Ubuntu 18.04 and I would like to explore more about it. I installed it alongside with Windows 10. I would greatly appreciate your help on this matter. Both flash drives were fine in Windows 10 if mounted.

If you happen to have chrome-remote-desktop installed as a Chrome Extension there's a good chance that is the cause of problem.

See Automount when clicking on disks in GUI file manager suddenly stopped working in Ubuntu 18.04 for solution.

Step 1: List mount-able devices

sudo fdisk -l

In my case I get:

fdisk output

Step 2: Create a directory to mount to

sudo mkdir /media/external

Step 3: Mount the drive now

sudo mount -t ntfs /dev/sdc1 /media/external -o  uid=1000,gid=100,utf8,dmask=027,fmask=137

Replace ntfs with the type, /dev/sdc1 with the device

If that does not work , go to /etc/inittab and change default runlevel from 3 to 4. With the next boot, your system will start GUI automatically, and those remaining options should be active.

  • Thanks, Bro for your help. Anyway, I figured it out lately as I learned from other member that chrome remote desktop may link your user account online and you are unable to mount your drive because other user has logged on. I deleted my profile out there after a while my usb drive has been detected. I logged out and reboot my desktop and mount the drive again and surprisingly my usb drive has been detected without hassle. – cortemplumist Dec 23 '19 at 15:58

Try this works for me,install USBGuard with synaptic.

Before the First Start Prior to starting the USBGuard daemon (or service) for the first time (but after installation) we need to generate a rules file for USBGuard so that the currently attached USB devices (in particular mouse and keyboard) keep working so that you will not get locked out of your system.

A rules file can be generated like this:

$ sudo sh -c 'usbguard generate-policy > /etc/usbguard/rules.conf' After that, you can safely start service usbguard:

$ sudo systemctl start usbguard.service And you can make systemd start the service every time your boot your machine:

$ sudo systemctl enable usbguard.service
