How to a drop tablespace ?????

Question

Hi Expert !!
I am living my life in ORA errors. To describe the complete picture:
1) We have a partitioned table whose partitions reside in multiple tablespaces.
2) One of the datafiles got corrupted where one old partition resides.
3) We are not interested in restoring the corrupt datafile and no more require that partition.
4) How do I drop the partition or tablespace?
Well, I have tried the following but no success:
startup mount
alter database datafile 'C:\MYDB\DATA\SALES_2005_TS1.DBF' offline;
alter database open;
conn sales/sales
SQL> ALTER TABLE sales_range DROP PARTITION sales_2005 update global indexes;
ALTER TABLE sales_range DROP PARTITION sales_2005 update global indexes

I did search on net and metalink but unfortunately couldn't find anything useful. I did try metalink note 267125.1 but again no luck.
Could any of you shed some light on this?
Regards

What about the following :
SQL> create tablespace test1 datafile 'E:\oracle\oradata\DEMO102\test01.dbf' size 1m;
Tablespace created.
SQL> create tablespace test2 datafile 'E:\oracle\oradata\DEMO102\test02.dbf' size 1m;
Tablespace created.
SQL> create table x ( x number not null, y number not null ) partition by list (y) ( partition p1 va
lues (1,2,3) tablespace test1, partition p2 values (4,5,6) tablespace test2);
Table created.
SQL> insert into x values (1,3);
1 row created.
SQL> insert into x values (2,6);
1 row created.
SQL> commit;
