Filesystem corruption

[Volker Wysk]

Hi!

I've brought my machine to the computer shop. They checked everything,  
especially the PSU and the main board. All the capacitors are okay.  
They couldn't find anything.

The main board is quite old, must be more than ten years. The HDD is 3  
1/2 years old.

Now I still don't know the reason of the data corruption, which  
wrecked my Kubuntu system. I've installed a new Ubuntu-19.04, and  
found no corruption so far. The problem can't be reproduced. This  
includes my dm-cache, which I've set up anew.

I'm worrying that the problem might hiddenly continue, and I don't  
notice in time.  :-(  Good thing that I have multiple backups.

Thanks to all contributors to this thread.
