No big deal. |

99.9% of the data is backed up. I was just hoping to recover the last |
| 28 |
0.1% (picky huh?<g>). Now that I know one of the main drawbacks of |
| 29 |
fakeraid, I think I'll move ahead with software RAID. |

OK, so I've partitioned the first disk as a single linux partition |
| 32 |
(/dev/sdb1, ID 83, Linux). |
| 33 |
How do I use sfdisk to transfer that partition scheme to the other |
| 34 |
disks? Is it not sufficient just to partition the other two disks in |
| 35 |
the same way as the first? |
