I encountered a strange situation 2 days ago. I rsync my pdf files periodically between my harddrives. rsync showed no differences between two folder trees, but if I did `diff -r` between the two, 3 pdfs came out different.
I checked the three individually but they showed no corruption or changes either side. How can this happen?
Edit: the hard drive copy is previously rsynced from this copy & both copies are mirrored with google cloud bucket.
The 3 files which showed different have the same MD5 checksum
