+### Please describe the problem.
+
+Two regular repositories created with the assistant, one on the computer and one on an USB stick cannot synchronise. Log reports problem with the index file:
+
+     /media/usb/annex/.git/index: copyFile: does not exist (No such file or directory)
+
+### What steps will reproduce the problem?
+
+Create a repository and then another on an usb stick (with `Add another repository`) and add a file to the first one, it doesn't synchronise.

+
+git-annex 5.20141125 from Debian Jessie
