How can I recreate my git directory and working tree?

How can I recreate my git directory and working tree?

My hard drive failed. No backups. (I know. I know.) Managed to clone the
drive and recover most lost data. However, files and directories which
were prefixed with dot (or blob) are now without their dot. So I have a
visible directory called git with files (COMMIT_EDITMSG, config,
description, HEAD and index) and directories (branches, hooks, info, logs,
objects and refs). The objects directory has directories (eg. 00, 0a, 0b,
etc.) and they each have files with SHA1 hash filenames. The
git/objects/pack directory is empty. So from what I can tell... the data
is there. I'm hoping I just need to rename the directory(ies) and
filename(s) and maybe it'll all work again. Or is this wishful thinking?
Perhaps I should have added I'm using a Mac.
