It's a myth! People need to stop worrying or even considering that their CF card is going to stop working or run out of space when using it in an Amiga. The people who say they run out are just quoting bullcrap from other uninformed people who don't know anything about the AmigaOS. It doesn't constantly write to the hard drive like some OSs do, and even when a block in the CF card has been written to the maximum number of times, it becomes unavailable, so the CF card doesn't become unusable, the capacity just slowly decreases over many, many, many, many years of usage.
