+### Please describe the problem.
+
+When running fsck (fast or slow) from an S3 remote that has anonymous access and git-annex publicurl set, it fails only on the files that get chunked into multiple parts because they exceed the configured chunk size for the remote.
+
+
+### What steps will reproduce the problem?
+
+- create repo
+- annex a file
+- set AWS creds as env vars
+- initremote S3 special remote with chunk size smaller than the file size and publicurl
+- push data (authenticated) to the S3 remote, ensure it get chunked.
+- unset AWS auth vars (and remote .git/annex/creds if necessary)
+- fsck from remote should fail on chunked file
+
+
+### What version of git-annex are you using? On what operating system?
