Unfortunately, I'm afraid it's not possible to delete the datafile
without dropping the tablespace. If you try it you'll have the datafile
dropped status as recover. If you've got and export, try deleting all
objects allocated in that tablespace (if not possible, drop the
tablespace) and importing then from the last export.
A couple of things:
I suppose you can obtain table information from catalog, althoug the
datafile is corrupted. So, to know witch tables are in that tablespace
you can do:
select table_name from dba_tables where tablespace_name='X';
If they're indexes:
select index_name ftom dba_indexes where tablespace_name='X';
Then, drop the tablespace, recreate it again and import the
tables/indexes from the last export file.
Other way, in case you've shutdown the db and cannot open it due to that
error, is to list the content of the export file:
imp FILE=<last_export_file> show=y

Hope this help, although am not very sure. :( -- =
