Better mount the filesystem with the sync option. Then every write goes

turn off the disk's write cache (or set it to write-through). Together
with ext3's data journalling mode, this should give you the most
reliability you can get - and the worst performance. :-)
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.

I speak only for myself, and I am unanimous in that!
