There are file system tests in LTP http://ltp.sourceforge.net/ including one called fsstress which is good for stress testing. We would typically do power-off-recovery testing with fsstress running. There are also tests in mtd-utils: http://git.infradead.org/mtd-utils.git We tend to run the integrity test as a basic test of whether things work, but it is best if it can unmount the partition. There are a bunch of tests in mtd-utils/tests/fs-tests that are run by the run-all.sh script there.
