and transferred the contents to the 1TB Samsung (attached via Firewire 800 to the MacMini Server) without any problems. ~ 1.7 MB/s over 802.11g. Initially, Win7 said that the drive might not have been shut down properly, and it ran chkdsk (but didn't fix anything).
Dunno.
But it's working over the network, without changing any filenames or running "dot_clean", and that's good enough for now.
Cheers,
Scott.
(Who sees he is going to have to spend a lot of time messing with Win7 to try to make it look less cartoonish...)
