While these are excellent suggestions, they are not "the
most reliability you can get" from a disc. However, to get
much more reliability without adding an UPS requires an
entirely different and more intrusive type of approach.
By intrusive, I mean "more visible to the application",
i.e. requiring special cognizance in the application of
when it needs to "commit" operations.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
