No, udev doesn't "keep" that info. It's just the piece "routing" kernel
events to whatever user space software needs to know about it (e.g.
"an USB stick has been inserted" or "a block device just appeared" --
as you see, one phisical event may well lead to a whole flurry of
things happening).

But if I were you, I'd see whether udisks is managing your DE's
perception of "disks". See [1]. Do you have a binary called udiskctl?
Another way to try to home in on the problem would be to just "reset"
the DE's memory, e.g. by completely logging out and back in,
without rebooting. Is the ghost gone? Then you'd know your DE is
dreaming. Otherwise it's seeing "something out there".
