I  don't think  anyone said  it was  going to  be easy,  only that  your
primary focus should be simply to get a good copy of the raw unencrypted
partition  while  it was  still  available  using simple  techniques  as
quickly as possible.

If you have obtained it, your next goal should be to figure out now what
to do  with it. As  I understand  it, you wrote  74MB of garbage  at the
front of that partition. This will have undoubtedly destroyed filesystem
metadata and some  other data. Can the filesystem be  "recreated" in the
first 74MB as just empty filesystem  space while leaving the rest of the
existing data and  filesystem in tact? I don't know  the answer to that.
Maybe there  is someone with  more FFS experience that  does. Presumably
you know the exact size of the  partition and so could at least recreate
an  empty filesystem  using newfs  with  the same  parameters. Could  it
possible to then stich in or reattach chunks of data into this from your
copy? Again, I don't know. Who does?

Any work you  do at recovery should  be done on yet another  copy of the
same data so that you can keep one "master" copy around just in case.

Some tools for recovering files can  be found in packages like sleuthkit
and testdisk. There may be others of which I'm unaware.
