hah, there it is:
------
Nokia-N810-51-3:~# dosfsck -n /dev/mmcblk0p1
dosfsck 2.11, 12 Mar 2005, FAT32, LFN
alleged total clusters: 490555

24530

34342
39248
44154
49060
Reclaimed 188077 unused clusters (770363392 bytes).
Free cluster summary wrong (250798 vs. really 438875)
Auto-correcting.
checked clusters: 51680
Leaving file system unchanged.

thanks! Ok, but I still can't unmount it :-/.

no, there isn't:
Nokia-N810-51-3:~# ps|grep D
  PID  Uid        VSZ Stat Command
 1637 root       1892 RW  grep D

hmm, I just rebooted with "init 6" (doing reboots with the UI is
sometimes weirdly fast and doesn't seem to do a full reboot).

Hmm, any more ideas? I heard people reporting that they reformatted the
internal SD card ... how does this work if you can't unmount it? Can you
disable mounting it completely? /etc/fstab only lists /media/mmc1 (weird
because this is the external card).

Thanks,
  Torsten
