MacBook Pro runnining 10.5.5. Since upgrading to Leopard my Express Card reader will not ingest on version 4.4.3.3. Any reason?
My experience is that this is a platform/driver issue.
I gave up trying to use an UDMA PCIe expresscard (Synchrotec) with Leopard.
It was fast, really fast, but would randomly crash, too often to be useful, usually in PM.
The firm said that the drivers were shaky and they hoped more people would complain so that new ones would be written.
I now use the SanDisk 800 and attach an eSATA drive through the ExpressCard Slot.
This seems to give us the quickest possible ingests to two drives.

If speed is your goal make sure your hardware is designed to use the pcie bus and not the usb bus that go into the expresscard.
