Hello everybody,
I`ve a ccd wich contains sensetiv data.
The Server crashed for technical reasons.
After it booted up again it told me to do a fsck.
I did.... and the data is gone now.
I think I shouldn`t have done it.... is there ANY way to restore this
file? I didn`t exspected that the fsck would be responseable for any
dataloss so does somebody know a method to restore this big file?
Came home and my X windows was frozen? This never happens. Tried to
ssh in and it seems dead. So I reboot, and fsck. Hundreds of errors...
fix 'em all! Programs begin segfaulting, another reboot, another fsck,
hundreds of more "errors" for fsck to fix. fsck segaults! sh
segfaults! Kernel panics!
It was bad ram. Replaced it. Booted bsd.rd, mounted the partitions,
tar xp'd from a recent tape backup and was back in business in less
than 1 hour.
Story is, fsck corrupted my data. Each pass corrupted more and more
data. Massive data loss! Lesson is, with a tape backup I was back in
business in less than an hour.

And I forgot to say: It`s a private Server but even privat can have
some value sometimes (and it was too big to backup. bigger HDDs are
planed to replace the CCD (later..)).
Maybe instead of buying bigger disks you should look into a backup solution.
Or does somebody know a extraction methode to reassemble the file?
You can restore these by using hexedit on the raw disk.

If you can see it with hexdump, you can probobly go out of your way
with a calculator to use dd with offsets etc. hexedit is user friendly
though.
