Missing files - restrict search

I am trying to get my PSE 3 catalog ready for conversion to PSE 6.

In PSE 3 I used the command reconnect all missing files. It starts the process
but finds that there is a missing drive, drive is an external one not being used
at this time. How can I tell PSE 3 NOT to search for this drive?

Meesage is:-

---------------------------
Problem with Shortcut
---------------------------
The drive or network connection that the shortcut 'target.lnk' refers to is
unavailable. Make sure that the disk is properly inserted or the network
resource is available, and then try again.
---------------------------
OK
---------------------------

I think that the first thing I need to have is a list of the files that PSE 3
thinks are missing with the path that it is looking for.

Is there a way to produce such a list?

Having got this I can then decide what to do, delete from catalog, move file to
where PSE 3 will find it, redirect PSE 3 to a new location.

Should have been more patient.

After running all night and two hours, before I went out, this morning came back
this afternoon to find a dialog to remove missing files from my catalog.
