@Glenn when I inserted my USB drive Caja recognized it automatically, so I guess I was lucky this time. I think it is useful that I add a quote from Luke about the importance of unmounting a USB drive after use:
What is the difference between ejecting the drive in Caja and unmounting it in Disks? Is it the same procedure just under different names or is one safer than the other? In fact Disks offers me three options:
- I can click the red rectangular button titled Unmount selected partition
- Alternatively, I can click on the grey button in the top menu titled Eject this disk
- And to add to my confusion there is another option in Disks right next to the eject button titled Power off this disk
