Unmounting and Mounting - Acting Weired

[freestyler]

I unmounted a partition /home from my system. I then went into the /home/ path and created a directory (I thought that it will give me some weird error but it didn't) "xyz". I can work with "xyz" directory like a normal directory but when I try to remount the /home this directory disappeared. Again on unmounting and accessing the /home directory I see the "xyz" residing at the same path. I can’t figure out where it went and from where did it come back? Please explain or let me know if I am missing something.

It sounds like it's being hidden when you mount, then unhidden when you unmount.

How are you mounting and unmounting the drive?

@WingedPanther: Why is that?
@relapse: What do you mean? Normally lol

Without looking at it in more detail, and doing research, I couldn't say.
