What's happening?
A really important point about calibre and any ereader is that calibre uses the OS functions to access the device. If the OS doesn't mount and display the device, calibre cannot do anything. If you can't see the device somewhere, and you can't access it with Explorer, Finder or whatever your OS uses, then calibre cannot do anything with it.

If there are problems with the device, such as the file system is corrupt, then they need to be fixed before calibre is used. With these sort of problems, calibre can probably do something, but will likely show an error and stop.

And that's sounds like your first post. You had a problem, the OS could mount the device but may have given you an warning. Calibre could then see the device and attempt to use it, but couldn't use it fully. And when this happened, calibre would have displayed an error. An error would have given hints about what the problem was. Without knowing what the error was, I'm not even going to make a wild guess at what the problems was.
