+I recently migrated an annex to SHA256 (without \"E\") and I'm now trying to clean the repo from unused data.
+I have a strange situation: there are 62G of unused objects:
+
+ $ du -ks .git/annex/objects/
+ 64334024 .git/annex/objects/
+
+but 'git annex unused' gives me only:
+
+ $ git annex unused
+ unused ...
+ Some annexed data is no longer used by any files:
+ NUMBER KEY
+ 1 SHA256E-s27--32efec98dc9e05442fc2385bb85d855a8c7824c68abd4ab5bf55a4dfe412b334.pdf
+ (To see where data was previously used, try: git log --stat --no-textconv -S'KEY')
+ To remove unwanted data: git-annex dropunused NUMBER
+ ok
+
+I've checked (through a small shell script) that none of the object is in fact referenced by any symlink...
+
+May I delete them? Shall I do some other checking/fscking/repairing?
+
+Thank you
