Lost partition and segfaulted with parted...

[Pigeon]

Hi.

parted 1.6.3 on kernel 2.4.19

I was about to do some resizing/reorganizing of a hdd with parted.

Basically I've got weird results, and
lost a partition. I tried to rescue it, but it detected a hfs, instead
of ext3.

At the end, I was albe to get it segfault too. (I can still reproduce
the segfault now with the same way, but anyway)

I guess the most important thing is to rescue that lost partition.
Directions will be appreciated, as I'm not familiar with various fs
tools like debugfs, etc...

Thanks.


What I've done with parted:


(parted) print

(parted) quit

--------------------

Then I run parted again:
