yes... that was the first thing I tried. But the card itself isn't even recognized.
dmesg in N800 just says (short form): cover is closed, setting voltage 3300 mV ... 2800 mV ... 0 mV
and there is no device created in /dev !
No chance to reformat or repartition such a card that doesn't exist in the OS.

Same with ubuntu... cardreader was recognized, sdhc card not.
Like there were no card in the reader. Absolutely dead.

If you or someone else has further ideas how I should test this card, please write down a post. It cannot become more badly
