For the damage question, yes
For the damage question, yes, with all flash media, if you're not using a
read only mount: http://cseweb.ucsd.edu/~swanson/papers/DAC2011PowerCut.pdf
Btw, you're crazy if you're not using a read only mount (or guaranteeing no
writes) for the rootfs of an appliance. ;)

This is why there is a power button. I suggest that you go to your PC and
yank the power cord. Whether it is running Linux or Windows, I suspect it
won't like it.
If you can't use the power button, then yes you can design a cape
that will let it gracefully shutdown properly. When I designed the

A solution would be to design a cape with a small battery to provide
enough power to enable the Beagleboard to gracefully power down when
it detects that external power is gone. That is probably the quickest
solution.
A second solution would be to audit the code to ensure the the file

I read over at another forum that the BBB could get damaged if it recieved
an unexpected hard power down.., is this true, what can we do about this?
Seems like a serious design flaw to me. One can't expect a power source to
be 100% stable and especially with a development board which is
What happens, or *can* happens when you just yank the power on a PC running
