Re: regarding raid disk.
2 or more disk failures *at the same time* are very unlikely. If a disk fails, the array will rebuild and is *fully redundant* again, as long as there is space enough. So replace each failed disk asap. Under special circumstances more than 1 disk can fail at the same time without data loss, this depends on the internal data layout.
Imagine a 4 disk mirror - if you loose the both mirrors you will survive, if you loose a mirrored pair, you loose your data. This example will apply, more or less.
Hope this helps!
Regards
Torsten.

Re: regarding raid disk.
If the status is still the same, this disk is dead.
Hope this helps!
