Not really good timing would probably be a good guess since "Intenso" is
a low cost brand around here (germany).

Thanks for your guidance. It's _not_ the sd_drive parameter.

It's actually just waiting for about 1-2min. After that the device is
readily accessible. (Need to force a re-read of the partition table to
mount though.)

Anyways I made sure that the data I wrote to the card yesterday is still
OK (md5sum) - although it's only around 1MB. I can do more tests tomorrow...
