This is my first post here, thanks for helping out! I have two external hard drives, HD #1 is NTFS and HD #2 is Mac OS Extended (I think this is the same as HFS+). I am copying many files from #1 to #2 (docs, pics, etc). I want to verify that all items copied correctly.
On #1 (NTFS), folder A reports this size: 8,137,638,456 bytes (8.14 GB on disk) for 2,721 items On #2 (HFS+), folder A' reports this size: 8,137,677,392 bytes (8.14 GB on disk) for 2,721 items
How can I verify that everything copied correctly? Kaleidoscope isn't helpful for this, since it just shows that the folders differ, without specifying how.
Diff reports only this: that every subfolder in A' has .DS_STORE :
diff -r "/Volumes/WD Passport/A" "/Volumes/My Passport/A'"
Only in A': .DS_Store
Only in A'/SUBFOLDER: .DS_Store
Only in A'/SUBFOLDER: .DS_Store
...
How can I verify that everything copied correctly? And is there something about NTFS and HFS+ file systems such that copying from one to the other results in different binary representations of files?
.DS_Store
files add up to (approximately) the difference? – Sparhawk May 30 '17 at 2:13
