The symptom is way trickier than the CHA error message, but I'll just skip them for the moment. In hope of solving the problem, I opened the camera card slot and found one of the pins bent. Then i suddenly realized that the card is wasted pretty much due to the pin-missing card reader as well as this defected on-camera card slot i've been using all along.
It actually surprised me when the pin-missing card reader actually did work at first; I didn't give too much thought of the consequence of the missing pin though. Now thinking in retrospection, it might be that the missing pins in the card reader as well as the camera card slot eventually freaked the card out.
I tried all I can think of to cure the card, but in the end even writing new partition tables and zero-ing it out didn't do the trick. These were done on my mac (windows freeze instantly on mounting the card as a mass storage drive); and I believe that if mac cannot do anything about it, there's not much I can do on the OS level (thought I might dig into my floppy disks to find the script in assembly language for zeroing out drives I wrote about 10 years ago --- if I can find a floppy drive)
Now I've got a new card and it works fine. My lesson is, make sure that card reader/slot has all pins working (or at least no pin is obviously impaired), even when you're card reader/slot seems to be doing reading/writing data.
