libgit2 error after laptop crash - any way to recover?

[alank99101739]

My laptop crashed (blue screen of death!) and after restarting I got the infamous "libgit2 error" on the project.  I have a backup from a day ago, but I put a fair bit of effort into it since then, so thought I would see if any way to repair it before losing that work.

Another thread mentioned creating the "objects" directory, but its already there.

Anything else I can try before restoring from backup?

Is the "repo.noindex" directory a git repository (like the .git directory using by git command lines). Does that mean I can use command line git tools to try and repair the directory?

Well, interesting.... so it is a git repo.... I am going to do a bit of Google hunting on git repos to see if there is a way to recover it.  Looks like it lost the "refs/heads/master" file when it crashed. (Most people say throw away your .git directory and start again...)

$ git --git-dir=repo.noindex fsck --full
error: Invalid HEAD 
Checking object directories: 100% (256/256), done. 
error: refs/heads/master: invalid sha1 pointer 0000000000000000000000000000000000000000

Everything I read sounded dire, so I restored from backup. After I restored from backup, "git --git-dir=repo.noindex fsck" still reported it as corrupt, so maybe its not a standard git repo somehow or other. Maybe standard git does not use SQL Lite for the repo files...
