I wonder if tar might be able to capture the data from the NTFS disk even if ext3 might not be able to handle maximum paths or something. -- Robert Riches spamtrap42(a)verizon.net (Yes, that is one of my email addresses.)

Even if you are doing just a straight copy, it has the big advantage over "cp" if you want to (or have to!) stop and re-start the copy. The real advantages of rsync come if you are copying over a network, but even for local copies I think it is a convenient tool.
