OK ! So you can't tell me what i need to have a job running that could help me
test if this is a fatal error or juste a false alarm ?
I think that my jobs are not running because of an another bigger mistake I've
made and am unable to locate !
here is an older message to refresh memory ;-)

I don't think that will work. I recommend that you do not put min/max block
size directives unless you are forced to, and almost certainly Bacula will
not work with those values, which are what the drive supports but not
approprate for Bacula blocks.

Yes, I should have mentioned, that as far as I can see from the write part and
the seek/read back part, it worked.
That said, as I mentioned, I believe that the WEOF error is indication of a
bad driver (or Bacula not understanding Win32 error codes, or a real
problem), and I wouldn't run my tape drives that way.
