It look to me like registering for kEventClassVolume /
kEventVolumeUnmounted carbon events would do what you need. This will
tell you the cRefNum of the unmounted volume (once again though after
it had gone).

* kEventClassVolume / kEventVolumeUnmounted
*
* Summary:
* An existing volume has been unmounted (or media ejected).
*
* Discussion:
* This event is sent to all handlers registered for it.
*
* Mac OS X threading:
* Not thread safe
*
* Parameters:
*
* --> kEventParamDirectObject (in, typeFSVolumeRefNum)
* The volume refnum of the volume that was unmounted. At the
* point when this event is sent, this is no longer a valid
* volume refnum, and cannot be passed to any File Manager
* API; it is useful only for comparison with cached volume
* refnums in your own data structures.
*
* Availability:
* Mac OS X: in version 10.0 and later in Carbon.framework
* CarbonLib: in CarbonLib 1.3.1 and later
