	I am modifying the C code for the old Tecmar T-Disk (yep its still
ticking!).  I now have it running with FFS, but can't get the old code to
properly tell if it is being run after the disk has already been mounted.

	I have tried the following:

/*      This calls up a requestor!!*/
	lock=Lock("dh0:c", SHARED_LOCK);
	if (lock != 0)
	{
		UnLock(lock);	 
		return HDERR_IsMounted;	
   	}
	This works fine if the disk has already been mounted.  It returns what 
you would expect.  The problem is that it prompts for DH0: if it is called 
before the disk is mounted (the normal case).

        Is there a way to check for the existence of a device or directory and
not have a requestor if the check fails?
