Disk is broken can't start Oracle database

I run small Oracle 7.3 database in NONARCHIVE log mode on NT with 4 disks . I have also full database export.
Suddenly one of disks is broken. That disk is not Nt system disk or disk where Oracle server installed, but I can't startup Oracle database. Is there any way to :
1. 'say to Oracle' don't use files on broken disk and startup Oracle 2. read the name of lost files (or tablespaces) on broken disk from oracle server (maybe from dictionary ).
3. repair tablespace (even empty) which resided on broken disk to the other good disk

The name of tablespaces is similar name of files e.g. TS KD, file is c:\oradata\KD_DATA.ORA and if I can know name of TS I can remember name of files.
