Corrupt datafile

Question

Hello gurus,
I have a test db in NOARCHIVELOG mode and i recently discovered that one of the datafiles is corrupt and so i cannot open the database.
This is the error when trying to open db:
SQL> alter database open;
alter database open
ERROR at line 1:
ORA-01113: file 50 needs media recovery
ORA-01110: data file 50: '/fcrdb3/fcrlive/datafiles/fcrdata_lrg/lrgdata13.dbf'
I don't have any valid backups and i need to bring my test instance back online. I came up with the following steps to resolve the problem and i want you to
analyze it for me.
step 1. Mount the db
startup mount
step 2.drop the datafile -
alter database datafile /fcrdb3/fcrlive/datafiles/fcrdata_lrg/lrgdata13.dbf offline drop
3. open the database -
alter database open
4. check all objects belong to that tablespace:
select owner, segment_name, segment_type
from dba_segments
where tablespace_name='tbs_name'
5. export out all the objects in that tablespace
6. drop the tablespace - drop tablespace tbs_name including contents
7. Delete the physical datafiles belonging to the tablespace
8. Recreate the tablespace, import back the objects
Please will these steps above help in resolving my problem?
Thank you.
