Symptom
Mac OS X stops responding during a large FireWire-to-FireWire device file transfer (copy). This does not occur when Mac OS X is used with one FireWire data storage device at a time.
Solutions
Update to Mac OS X version 10.1.1 or later. For more information, see technical document 106634 "
Mac OS X Update 10.1.2: Enhancement and Installation Information"
Check with the manufacturer(s) of your FireWire devices to ensure that the latest device firmware is installed.
If the issue persists, use one of the following workarounds:
- Copy smaller amounts of data at a time.
- Copy the data from one FireWire device to a non-FireWire volume, then from the non-FireWire volume to your other FireWire device.
- Start up from Mac OS 9 to perform the file copy.
