I presume the OS only writes 'dirty' records back from the cache, which means that we need to make sure the 'dirty' flag needs to be set so the OS knows the record has changed.
Could you confirm this? If so, people who are modifying records without setting the 'dirty' bit could see their data silently disappear.
That is true, as far as I know. I brought up this issue when I first wrote about NAND flash at http://palmos.combee.net/blog/UnderstandingthePerforman.html
