As a matter of fact, there are. I am using an old Lenovo S20 tower and it does have card reader slots built into it. I never used them and so I never paid any attention to them. The physical labels on the slots match what appears in the unRAID screen, so that verifies the source of the displayed information. But these only started to appear just recently, and they appeared one at a time with a long delay between each one showing up (days, weeks?). Perhaps the last update to UD caused these to start appearing? But why the delay between each line appearing?
If that is all it is, I can live with them being displayed. I was just uncomfortable with not knowing what this was about.
Thanks for solving the mystery.
