whole partition is gone! [SOLVED]

Hello!

I've updated my system by emerge --update world, the only two things that were emerged were doxygen and udev. Then, after reboot the whole 70GB reiserfs (3.6) partition was _gone_, it's not visible even with fdisk... :cry:

I've definitely not changed the partition table, so it's very strange having 70 GB free space there... I had some problems with 2 other reiserfs partitions for / and /home too, they was reported as not clean on reboot but a reiserfsck from a live-cd helped.

I've read some threads about mounting problems after udev update, but since I have no /dev/hda6 any more, I can't try reiserfsck or else, so I decided to ask before I make the things even worse.

Is it possible to recover the data of a reiserfs partition by making a new partition on this place (without formatting it afterwards) and executing reiserfsck --rebuild-sb? Or maybe there are some utilities for it?

Any help would be appreciated

Are you sure your partition is gone? Boot with the liveCD and have a look.

Btw which udev version did you upgrade to? I too upgraded udev today, and now that I've heard this I won't reboot.

Yes, I'm sure, I've noticed it when I tryed to fsck it from the live-cd like other partitions...
Well, I'm in a re-partition phase now, I've reformatted everything to reiserfs for some weeks and since I can't move or resize may root reiserfs partition (it was reiserfs already), I decided to try out "~x86" keyword and Xorg v.7 before reformatting root partition and reinstalling gentoo, so it was udev-081... I thought it may cause unstable/unbootable system and not deleting whole partitions

I've downgraded to udev-079 and baselayout-1.11.14-r1 marked as stable, but no chance...
Can a defect hard disk drive cause damaging of the partition table? AFAIK defect drives just don't work any more...

I've made a new partition (with fdisk) of the same size and at the same place as my disappeared partition was and run reiserfsck --rebuild-sb and reiserfsck --fix-fixable on it, it solved the problem

That's great news nickless. I don't know what would cause this. Btw I did reboot later on, to the latest stable udev and baselayout and had no problems whatsoever. Anyway glad you got your stuff back.
