Hi Eric,

thank`s a lot for your fast answer !

I have compiled the newest xfs-tools and I was able to recover the 
Fileystem ide1(22,2) (=/usr) which has the same Problems at booting the 
machine as the ide1(22,3). 
After installing a minimal Debian on a new harddisk, I was able to do the 
xfs_repair on the ide1(22,2), and I was able to mount this partition and 
was glad, that all files of this partition 
where ok. 
I do the same at the ide1(22,3) and mounted it, but there was only the 
"lost+found" directory with many "lost+found" files.
A simply "df" showed me, that the capacity shows 80 % (the same as before 
the crash.)
Is there a chance, to rescue my files on this (=/home) Partition ?

Thank you for your help

Christian

That one mounted fine...

And this one has problems.

Can you run this through ksymoops?

This is odd, this is on the filesystem that said it mounted OK...

Maybe you can do an strace of the process to see where it stops?  Also,
make sure you have the latest version of the tool...
