ASM disk corrupted

 Hi,
I want to know if the diskgroup couldn't mount and the header of an asm disk corrupted (it is only my supposition), how should I deal with it? Will the data in  the ASM disk lose?
I know the kfed can repair the ASM header, and if it restores the disk header successfully, the data will not lose. And another way is to use the 'dd' command. It can clear the disk header, but I think in this way the data will lose, is it right? The third way is as ID 353423.1 said, but I don't know whether it is practicable, and I also don't know whether the data will lose.

Howdy, Stranger!
