Hello, I think i have seen enought flash failure to tell you what happens, i've created a system using linux for embedded systems with a total of 12000 units, for 5 years, in this time we have changed about 20% of theses flashes. What happens is not a single event, here it goes. - The flash just stop working, you can't read, you can't write, you can't do anything - Some sectors of the flash stop working, it gets corrupted somehow - The read of some sectors start to show errors like normal hard disks - When the sectors start to reach 100.000 write cycles, it gets slow to read, and the entire flash starts getting slower and slower My Solution until now: Make a big partition for the writable data, and turn it into reiserfs, it naturaly cycles the writes on each sector and you will be able to recover some of the data when it crashes And dont forget to make the software unlink the node before writing to it, then it will be a brand new file each time.
