Disk Crashed, NDF(Index) file lost I have database with : 

-two filegroups (PRIMARY and INDEX)

-three files .mdf(data), .ndf(index) and .ldf(log)

every file is on different disk, yesterday disk where was NDF file crashed so I lost that file.

No, you will have to do a restore.  Please see this reference on how to do file and filegroup restores.
