W.r.t. the latter, there's at least the sdc_watchdog (see Wiki) which will notify you when the SDCard is write protected...
What FW version are you using, anyway? 
P.S.: Just a quick thought: Without the sdc_watchdog, /media/sd is sometimes _not_ properly umounted when you remove the card without using 'safely remove SD' beforehand... no clue what happens when you reinsert it after it has not been umounted when it was write protected... maybe worthwile to check that out... |
It also could be a problem of the motherboard. I would suggest to contact the vendor and to send the device for inspection. It must be definitely handled as a warranty case.
