I ran sudo rsync -va --progress
from the root of one external drive to a folder on another external drive. The reason is that the source drive has an error-ful NTFS and I don't have access to a Windows PC to repair the NTFS.
10 hours later it said:
sent 608725204596 bytes received 19365712 bytes 15902210.53 bytes/sec
total size is 608586212274 speedup is 1.00
rsync error: some files could not be transferred (code 23) at /SourceCache/rsync/rsync-42/rsync/main.c(992) [sender=2.6.9]
I saved the entire terminal output. At the beginning, there are a few hundred Input/output error (5)
for files I actually don't need totaling roughly 2GB. OSX Finder "disk usage" tells me the source is 617 billion bytes, not 608 as in the above report.
Questions:
- Does the first portion of the verbose output (building a file list) definitely say
Input/output error (5)
for EVERY file that won't be copied? - Does
code 23
mean that all the files except theInput/output error (5)
ones were successfully copied?

23
only means (from the man page):For everything that could not be transferred, you'll get an error message. Note that the error messages could be about opening or reading directories, so you won't necessarily see an error message for each file that could not be transferred.
If your source has not changed, you can run the
rsync
again with-n
to see what it would transfer this time without actually doing the transfer.About the byte difference,
rsync
gives you the size of the files (how much data can be read from them). Are you sureFinder
doesn't tell you the disk usage instead?Also note that NTFS can store data in alternate streams or attributes of the files, and
rsync
will typically not transfer (is not aware of) those (and that can account for a lot as well).
