From Inside Macintosh Volume IV page 181.

        Type DrvQEl = RECORD
                qLink:     QElemPtr;       { next queue entry }
                qType:     INTEGER;        { queue type }
                dQDrive:   INTEGER;        { drive number }
                dQRefNum:  INTEGER;        { driver reference number }
                dQFSID:    INTEGER;        { file-system identifier }
                dQDrvSz:   INTEGER;        { number of logical blocks }
                                           { on drive }
            *   dQDrvSz2:  INTEGER;        { additional fields to handle }
                                           { large drive size }


* I think this is the field you were looking for.
