FireWire Hard Drive
     - Maxtor One Touch 200GB USB 2.0 / Firewire External Hard Drive

	Ensure that the FireWire drive you purchase supports multiple
logins. If the drive has a chipset that does not allow for concurrent access
for more than one server, the disk and its partitions can only be seen by
one server at a time. Disks with the Oxford 911 chipset are known to work.
Here are the details about the disk that I purchased for this test:
Vendor: Maxtor
Model: OneTouch
Mfg. Part No. or KIT No.: A01A200 or A01A250
Capacity: 200GB or 250GB
Cache Buffer: 8MB
Spin Rate: 7200 RPM
"Combo" Interface: IEEE 1394 and SPB-2 compliant (100 to 400 Mbits/sec) plus
USB 2.0 and USB 1.1 compatible
"

I guess they mean that most filesystems don't handle it.
