Fwd: Bad root block 0

[Roland Häder]

Hello again,

another thing: I could extract the "missing" metadata as you described 
to a compressed file. But I do not mail it to you, because it contains 
"security-breaking-data": My Online-Banking stuff. :-( If I do so, 
which will never happen - you just need to crack my password for 
"unlimited" cash.... :-(

Hm. Can you tell us what kernel version you were using at the time of writing
your files to encrypted device?
What do you mean by extracting "missing metadata"?

"unlimited cash"? Wow!

debugreiserfs can extract the metadata of a rfs-partition. With 
"missing" I mean that reiserfschk tells me that there's no metadata 
available. So here's a strange thing: debugreiserfs found it, but 
reiserfschk not...

Nope, not *really* unlimited cash... :)

What debugfs command found the metadata? Was it just plain "debugreiserfs -p"?
How much leaves/internal nodes were found?

Ah, sigh.
I thought Bill Gates started to use linux + reiserfs, but no...
