(Normally every DBA after that kind of failure considers at least 3 copies of control files on 3 different (physical) disks.)

Today I also had hard disk failure of developers DB but was lucky because it was not permanent - I managed to copy data files from this corrupt disk to another disk and after did what you was already advised (edit init.ora control_files to point to new location and 'alter database rename file ...') DB worked again. So just try this as well: NT will check CRC for you.
