o.k. this I do understand,

but is this related to my problem, that one directory can only be seen 
sometimes ?

If I just try to access this directory and it was not found I get no error 
message. Its hard to find out in what situation this directory can be 
accessed and if, if the error is thrown then.
At least to make a complete copy of this directory is not possible, because 
its gone again before the copy is finished.
This directory itself is not much important because it can be reproduced. 

But what I need is to keep this filesystem alive for at least the next 2, 
better 3 weeks. Most of the tasks will be read operations, but small write or 
at least copy operations can not be avoided.

Any suggestions?

Harald
