Why device cant see the memory card?
 

Card to work seamlessly ... when i pulled out of the N900 to another device, then I put back into my N900, device does not see it already ... On the other equipment with card works ... Do i damaged the slot for memory in my N900?

Just asking, did you turn off n900 before taking card out? Because if you didn't and did not unmount it i think it wont start working before complete reboot.

did you close the back cover correctly? there's magnetic switch triggering the sdcard's mounting/unmounting.

Re: Why device cant see the memory card?
 

when you open the back cover, the sd card get's unmounted, thus you can remove/insert it w/o shutting down the fr.

edit:
well, not the fr obviously, but the n900 (wish the fr had had such an easy way)
