Try moving around 35GB files between 64GB PATA Flash drives (technically 'SSDs') and 500GB Apple Time Capsules.
Some fun items:
- Cyrus mail spools can't be untarred on 'doze systems, because they contain files whose names have trailing dots ( "123." "543." etc) which are illegal on 'doze.
- Apple Time Capsule's implementation of Windows file sharing can trigger STOP errors on Win 7.
