You might want to turn off soft-updates because they rely more on the
hard drive cache correctly behaving than the alternative (the "normal"
mode, without sync or async). If you do so, file system operations will
be slower and you will suffer long fsck times, but at least your file
system will be consistent (which says nothing about your data).
