I have copied data to and fro in the ranges of 4GB and above. Once in a while I have seen the machine getting stuck. One work around I have found is after copying large data, before I eject I run "sync" from the command line. This command might take some time to finish. You can see the Pen Dirve LED blinking fast at this time. After this if I eject my Laptop never used to Hang.
Not a solution but a work around :). PD
