Yes, but inaccessible. I do claim "yes, it is" because I could
examine the filesystem's dd image with the fsdb tool. Furthermore,
I tried a trial version of a "Windows" recovery program under
wine. It showed that some of the files are still there.
My wish is that I get fsck to restore the hierarchy within my
home directory into lost+found/, while 1st instance entries
surely will have their (lost) names replaced by the respective
inode number, but that's no big deal (thanks to the file command).

Well, this is an obvious solution if you can access your data but
have problems with the system's startup. SUM is sufficient to
establish a network connection as a means to transfer the data
off the disk; another means would be to mount the disk inside
another running FreeBSD system.

The drive isn't defective. After the "surprise crash" is behaves
completely normal. But that's not interesting because I don't use
this drive, I only would access it if I needed another dd image
of the partition - it's just easier to deal with the image than
with the physical disk.

It does, and, most interesting, it replicates the error (the lost
inode entry) from the original partition.

I could move all home directories (of the other users) and the
archive directory from this partition. From the other partitions
I could copy the "important" parts of the system configuration
and "proprietary" service programs. The only thing that's not
accessible due to the defective inode entry is my own home

I'm glad I don't see a need for this at the moment. Well, this
may be a strange confession, but having used FreeBSD since 4.0
should have put me into the state of being able to solve this
problem on my own, but sadly, I'm not. Too diffuse, too complicated.

They work fine. Even Firefox that is often being called to be
slower than Opera runs much faster.

I didn't play with optimization anyway. The german -questions
list gave me advices how to do system generation correctly.
And FreeBSD 6 didn't live very long here. I used my version 5
system many years without any trouble, so I decided not to
run version 6 (except for toying around with PC-BSD) and instead
wait for 7.0 to be released. After release, I did put up a
system, but put the harddisk onto the shelf because I felt
more comfortable in my still working version 5. So I'm glad
I just had to replace the harddisk when my version 5 system

I'm such a frightened guy when it comes to "Windows"; I don't
trust it further as I could throw it. :-)
Judging from the speed of the base system (general usage speed),
drives don't seem to cause the increased amount of time needed.
Diagnostic means of FreeBSD show normal operation temperatures
and voltages, memory is well, S.M.A.R.T. data is okay.

It's out of date as soon as it arrives in the shop where you can
buy it. And if you take it out of the shop, you can't return it
to get the same amount of money back that you spent to buy it.
Sometimes I miss the good old Sun and SGI systems. Yes, they were
expensive, but they lasted a man's live long. :-)

Something like "while(1) make buildworld"? :-) I'm a really
really mean guy. Another box in the room and I can't move

No problem, I can put the PC-BSD disk into my system, re-init X
and see what's happening. And I can use its fsck_ffs to see which
reason it claims to have why it won't be able to restore my data. :-)

That's a thing I always admired when using FreeBSD. When new
technology is forced to be present in order to keep a working
system, I should look around if there are certain switches that
exclude the new stuff and let FreeBSD 7 behave in "the old
fashioned way", for example, no SMP (because I have none).
By the way, I've tried both ULE and the standard scheduler.

Yes, they ARE strange, and I simply cannot explain them, that's
what frightens me most. The newer I update the system, the longer
the compilation process takes. The system, as mentioned before,
runs fast and fine, as long as no X is involved.
Another thing that could be an explaination of the slowlyness
is the urge of the developers to put the newest GUI toolkits
onto the same functionalities. Maybe I should replace every
Gtk 2.0 based applications (here: Gimp, X-Chat, Sylpheed)
with ones using the respective Gtk 1.0 toolkits that ran so
fine on FreeBSD 5.
I would, for example, never be so stupid to try out KDE 4
on my system - there would definitely be no joy.
