no, nothing.
how do I know now is hdparm -I or -W lying? (-I says it's enabled and -W0 says it was disabled just fine.)
my drives do not support cache flushes, I guess your drives do?
drivers/ide/ide-disk.c:write_cache() if (!ide_id_has_flush_cache(drive->id)) return 1;
cat /proc/ide/hda/settings does not work, either
