Trouble transferring data between external drives - shrinking file size?

1 Answer

Answer :

Hopefully you get someone to answer here. I was curious about this, so I started googling. These are my results. http://support.apple.com/kb/HT2355 Journaling doesn’t seem to have any meta-data. This is probably what you were thinking was being stripped from each file in the transfers. It’s possible that it is meta data of some sort, but I don’t believe the journaling is the cause. Here is someone who agrees with me, read their response at the very bottom of the page. “Too late to include in my last reply, I noticed your comment about needing to copy the files to an unjournaled partition somewhere. Journalling doesn’t have any effect on file size or fragmentation—it is essentially a method of recording pending file changes so that should that process be interrupted, the file system knows what files might be out-of-date without going through the entire file system.”
