formated the card as soon as i had it.
trying it out on my WG II to see if the problem can be repeated on a different camera.

Hello!
Got myself a K30 ( febuary) , bought it initially with an 8 Gb 100X SD card, and since i was filling it up rather quickly i bought a lexar 16Gb 400X class 10 card.
I'm getting "memory card error" messages on startup which go away once i do a reboot.
After the reboot i can do 400 shots with any glitch...
I'm also getting 'can't store image' messages while in shoot, this is after a normal startup with no indications that there is a problem.

any ideas??

Thx!!
A.
