Sure, but let's take it back on-list. Then other people can help answer, and later users can benefit from seeing the answers.

Running verify-pack like that is slow. If you have a recent version of git, you can use:

  git rev-list --objects --all |
  git cat-file --batch-check='%(objectsize:disk) %(objectname) %(rest)' |
  sort -rn

to get a sorted list of the largest objects that are reachable. If you don't see your big object there, try doing:

  git rev-list --objects --reflog

for the first line, to see if it shows up in the reflog.

If the object is only in the reflog, the simplest thing is to expire the reflog and repack:

  git reflog expire --expire-unreachable=now --all
  git gc --prune=now

If it is reachable, then you'll have to actually rewrite history to get rid of it. Since you know the sha1 of the object, you can find which commit introduced it with:

  sha1=...whatever...
  git log --all --no-abbrev --raw | less +/$sha1

That will dump you in less, with the sha1 highlighted (if it comes and goes through history, you may need to use "/" to find other instances).
