You can use smartctl to pull the S/N off the drive. |

Short answer: lots of things can go wrong. It might be as simple as |
28 |
removing the failing drive from the array. But it doesn't matter, back |
29 |
up the un-failed disk right now if there's anything important on it. |

*Then* play around to get the array working again. |
