Cloning HD, error creating hard link for file in Xcode-beta.app.
At first I thought that the drive was damaged, but the error still occurred after reformatting it. SuperDuper’s Dave Nanian:

Note the “2” for “AuditIssues.strings”. Here are the two files with the same node:
The fix is to make the two files independent copies:
Now the files have different inodes:
