It shouldn't, however if the data is corrupted elsewhere then scp probably
won't detect it. Corruption on the network should be caught by the MAC
in the ssh protocol. It's also possible that there's a bug somewhere.

Can you isolate it to one machine? ie if you do "scp files*
localhost:/tmp" on each machine, is the corruption present on both or
just one (and if so, which one)?

rsync?

usually comes from bad judgement.
