I have the impression now that the drives are lying and it's not the fault
of the drivers or cards. The same problem occured with a fourth card and a
non-Linux system.

Anyway I also tried changing the timeout to 86400000 milliseconds (one day)
and it made no difference. So again I stop blaming the drivers.
