i bought a 512mb picture card for my fujifilm A340 and about 80% of the time i take a picture it says "Write Error" i checked the fujifilm Q&A, but all that said to do was wipe the card with a soft cloth and to format it. after formatting it, the problem was reduced to about 50-60% of the time. im just curious if there is something i could do to make this problem either go away entirely or to reduce it from happening as much. any help would be greatly appreciated. Thanks
