Opensuse 10.2 ruins reiserfs


A 300 MB USB hard disk that has backed up many systems
is unreachable since plugged it in while running openSuse 10.2.

It had reiserfs partitions on it. Bottom
line is OpenSuse 10.2 destroyed the partition table on
the external usb disk. Now any Linux just sees
/dev/sda instead of /dev/sda1 ... /dev/sda8. What can
I do to recover my year's of work on that hd?

In addition to destroying my external hd here is
what happened to my internal hd.

I had been multi-booting on my internal hd under Windows and
many linux updates. I installed openSuse 10.2 on a
partition that had previously used openSuse 10.1, some
beta releases of openSuse 10.2, and finally Edubuntu.
This partition was reiserfs. After I installed openSuse
10.2, booting my old Ubuntu from a different partition
always failed to mount the two reiserfs partitions on my
internal hd. I finally discovered that both of these
partitions had been changed to ext3. No problem with
the internal hd. I just changed the /etc/fstab from
reiserfs on these two partitions and everything on that
hd showed up again. It is the external hd that I am
concerned about. Do you think it tried to do the same
thing to the external that it did to the internal and
just lost it? If so how can I recover?

Yet another Suse partition problem - I'd take that as a hint.
As root, try "fdisk -l" to see what the partition table(s) look like.

For recovering partition table where the data is still intact (i.e. no writing has ocurred to the old space - especially mkfs), try testdisk.
VERY handy utility.

Before doing anything to your external hd copy raw data from it to a file (use dd comand). In case anything goes wrong with testdisk there's a chance, that you can copy raw data dumped to a file back to the external hd and try over again.

Is this a troll? I haven't had any partition problems, haven't used an ext. HD though. I do use USB sticks in FAT32, I can read all Reiser, EXT, NTFS drives in my system, no corruption at all.

I resent anyone thinking this was not the truth. Check it out on Suse
bugs. Just because something happens ok many times does not mean it will
never go wrong. Suse was great till this scared me half to death. I
solved it by switching to ubuntu.

Whilst hopefully not rising to the bait of a Troll -- I'd suggest that the OP does some limited reading before installing / upgrading an operating system.

Resierfs is "deprecated" in Opensuse 10.2. You should use EXT3.
If your hard disk was Reserfs you should really have converted it to EXT3 before insalling SUSE 10.2. Reiserfs is not the recommended file system any more. There might be an extension to EXT3 (Ext4) appearing later but EXT3 is currently as stable as anything else and rarely breaks if ever.

I must admit I haven't had ANY partition problems with SUSE even when recovering from a system hang.

I've even been using ntfs-3g with FUSE for WRITING to external USB drives formatted with Windows NTFS file systems.

Partition problems in recent SUSE distros are fortunately relatively rare unless you install experimental / dubious modules with highly customized kernels.

Cheers

I've had my fair share of partition problems but I think it's mainly due to reiserfs and not SuSE. The reason I say this is:

First time I installed SuSE 10.1 on my computer on a separate partition I selected reiserfs as the file system. Then every time I played a new song my sound reset to 30%. This also happened to a friend of mine. I installed the same OS with ext3 and that problem was solved, told my friend about it and his problem was solved. I don't know how this is possible but it's true.

Second and third problems include PC-BSD. First time I installed it it had this ugly LILO or some kind of bootloader which showed:

1. UNIX/BSD
2. ???
3. DOS
4. Linux

So BSD could boot and Linux could boot and "DOS" which is Windows could not boot. I did fixmbr with the Windows disk and that didn't help and then I was totally screwed and I re-formatted. Not too long ago (about 2-3 weeks) I thought let's give PC-BSD another try it seems such a nice OS...

This time things looked like this in the bootloader

1. ???
3. Linux
4. DOS
5. Boot from CD/DVD

There wasn't a '2'. I tried booting Linux...nothing happened. Tried booting option 1 which I assumed was BSD...nothing. In the end I could only boot up into Windows and boot from CD. When I booted into Windows and I checked partition magic to remove BSD. My whole sdb showed "BAD" meaning it didn't know which file system it was. I tried formatting the whole drive with PM...no luck it just couldn't. So I booted Ubuntu dapper and tried formatting it from there...(2 partitions, NTFS + EXT3...not luck it also showed "BAD". So then I just told GParted thingy to take the whole drive and install Ubuntu on it...finally it managed to make a file system on it...ext3 and it allocated a 4GB swap :| . I was just happy I could save the drive...

However this is my personal experience...yours may differ

Where do I find instructions for converting my "reiser to ext3" partitions?

Google Results 11 - 13 of 13 for "reiser to ext3"
Some are announcements that distros are changing.
None tell me how to reformat my partitions.
I think it is ok for you to say I have done limited reading. But such comments do
not encourage users of M$ and other distros to switch to your favorite distro.
Much more helpful would be to publish how I change my partitions to ext3.
Just a URL will do the trick.
Of Google's 13 results at least one claimed that he could not convert
reiser to ext3.
