I forgot to comment here on the main problem... How did Brian lose those apparently large numbers of images? If he didn't do it by accident there is a serious system problem which, I suspect, is not an accident.

No, not 9 months on one card;

That wasn't me, saying 9 months on a card is a bad idea, that was Bob B.

one card used twice, reformatted after he first
use ( actually I have used this card umpteen times).

At the end of every shooting session, I upload the new images on to the
computer in the appropriate sub-directory. But I leave the
pre-existing images
on the card, until it is full or nearly full, then with all new images
uploaded, I
erase the card and reformat it in the camera. Works for me with the E-3..

Which is just what I outlined as my procedure. Your reported problem
then must lie with later actions.

The question remains as to how you lost images.

Perhaps you don't back-up often enough?

Perhaps you do it the wrong way? There are two general ways:

1. Incremental back-up, where all that is done is to copy any files not
already on the back-up medium to it.

2. Synchronization. This assumes that what's on the primary disk is true
and complete. It then makes the back-up an exact copy of the main disk.
This may involve wholesale replacement of the existing back-up or
software that copies new stuff and also deletes anything already on the
back-up that is no longer on the primary.

Synchronization is NOT your friend. It spreads any mistake into the
back-up, thus eliminating one of its main purposes by carefully
eliminating the very copies you may later discover you need because of a
disk failure or fumble brain/fingers.

I just checked; I am using a 2 GB CF card. .Amply big enough for me.
I'm not shooting much these days anyway. Must check if 2 GB cards are
still
available here.

There should be a sea of them available used. Used ones should be
tested, but as you say, you are already using used ones, "actually I
have used this card umpteen times"
