Raspberry switch off corrupting SD card

[dmantampfl]

Hi,
I am using XBian alpha. I will be moving to beta very soon. Shutdown may not always be an option as the device is always connected to power. So that I can switch to XBMC without going to power supply board.

When I say card is lot, it is not just OS lost. Because, I am not able to use it for anything else after that.

I am planning to buy a power switch for raspberry. Hopefully that will make things better.
