Cowon j3 sd card removal problem, any ideas ?

[ip8g_345]

I finally managed to remove the card using needle ended pliers.
Then I insert and removed card for about 10 times into usb adapter which come with it and I paid attention that last few times I needn't apply a lot effort to remove it

I just put the card again into J3 and now I can remove with no problems : I press card with fingernail it clicks and pops for half of it length so I can just grab it with fingers and pull it out.

My explanation is that it probably was a very slight imperfection on the card which get polished when I pushed/pulled it multiple times from USB adaptor. It looks like the problem wasn't with J3 at least in my case ( as I mentioned many people complain about problems, but may be at least in some cases the card is the problem)
