directory error mesage advice- besides reinsert the CF card

whats going on. I know I'm not alone with the directory error issue with the 1K. I used to get this message less frequently but now it seems to piss me off on the daily. What cause's the directory error message and is anyone aware of ways to prevent it from coming up?
I've tried the eject >re-insert ish and occasionally its a fix but most of the time I end up saving to internal memory in one of my programs. Its a good backup but takes time to rewrite the memory and there has to be another way around this issue. Words of wisdom, slander, needless banter apreciated- thanks peace

alright ask a stupid question get a stupid answer. I asked akai about this and they basically told me create a new folder b/c the one I was using was full. So create new folders and that should fix it.
