Like Simon said, sr is your optical drive. I guess you are missing |
| 72 |
something in the HDD driver stack. Maybe you should post your kernel |
| 73 |
config and lspci. |
| 74 |
|
| 75 |
Or, like Simon suggested, the drives don't spin up fast enough. |

Thought the same. Using `make oldconfig` is also highly recommended. |

I think that is a different error ("unknown super block", "unsupported |
| 93 |
features" or something similar). |
