did you actually _format_ it, or just repartition it? |
| 8 |

I see three possible options: |
| 10 |
1. repartition it, hoping the filesystem has not been touched |
| 11 |
2. run an undelete tool on it (don't know if they exist for reiser, |
| 12 |
certainly not for ext3 |
| 13 |
3. give up! |
| 14 |
|

If you "formatted" it, ie wrote "zero's" all over the place (or whatever |
| 16 |
a format does), then good luck, you'll need an "undelete", if there is |
| 17 |
such a beast for reiser. |
| 18 |

If you just repartitioned it (ie. wrote to the partition table that it |
| 20 |
was now an xfs instead of reiserfs) and you've done nothing else, not |
| 21 |
even mounted it since, then you _should_ just be able to use fdisk to |
| 22 |
redo the partition table. |
| 23 |
|
| 24 |
Use caution! I'd back up the drive with dd or something first, just in |
| 25 |
case you screw it up. |
| 26 |
|
| 27 |
repartitioning doesn't necessarily screw with the actual data on the |
| 28 |
drive - just the partition table. I once blew away my partition table |
| 29 |
by mistake, and rebuilt it by trial and error by guessing how big the |
| 30 |
partition where from memory, and then mounting them to see if I got it |
| 31 |
right. |
| 32 |
|
| 33 |
Of course, if you've run anything like mkfs over the partition then |
| 34 |
you're probably screwed. |

| 39 |
so long as it created the partition without mkfs-ing it! |

*lol* you can't let an opportunity like that pass by... |

Surly to bed, surly to rise, makes you about average. |
