Hi,

When I insert a Pendrive on USB port, it recognizes it,and I am able to read/write to it.

After using it, I press the tiny button on Nautilus to unmount safely.

On next reboot, I get a boot page that prompts me to run "fsck" on Root Volume.

I happens every time a USB device (Pendrives, Mobile Phone, Hard Drives) is safely (or not) unplugged

Please tell me what info/logs/files are needed in order to have advice/support from you.

Regards,
David García.
