I installed automount (autofs), so that the USB drive would be unmounted a couple of seconds after I stopped looking at it (i.e. cd'ed out of it, or closed the relevant Nautilus window). In this way, it's unmounted before I physically detach it, and the buffers will be flushed. Well, that's the theory. Jim helped me get it working at the fix-up night, but I noticed last night that the drive was never unmounting.
I just want to know what I'm doing wrong with lsof. Even when I'm looking at the USB drive with Nautilus, I can't see any mention of the usb drive in the lsof output. Consequently, I don't know how to find what's keeping the drive mounted.

Can someone remind me how to find out what's keeping it mounted?
I tried lsof, but couldn't find any reference to the usb drive at all, even when I was viewing it with Nautilus.
Sorry if it's too simplistic, but what does unplugging the USB drive do? And which distro please?
On Ubuntu Nautilus, I found that my USB camera auto-mounted and -unmounted flawlessly, plus desktop "sd0" icon popping up and disappearing.
Is there some purpose for keeping unmounted storage attached to the system?
