why 2 ieee ports in Maxtor OneTouch III FireWire 400 and USB 2.0?
Nothing in literature with external drive, nor on
manufacturer's web site explains why the there are two ieee 1394 (firewire) ports. anyone know the purpose of having two? --David |

i stand Corrected... thank you WiKi...
FireWire can connect together up to 63 peripherals in an acyclic topology (as opposed to Parallel SCSI's Electrical bus topology). It allows peer-to-peer device communication, such as communication between a scanner and a printer, to take place without using system memory or the CPU. FireWire also supports multiple hosts per bus. It is designed to support Plug-and-play and hot swapping. Its six-wire cable is more flexible than most Parallel SCSI cables and can supply up to 45 watts of power per port at up to 30 volts, allowing moderate- consumption devices to operate without a separate power supply. As noted earlier, the Sony-branded i.Link usually omits the power wiring of the cables and uses a 4-pin connector. Power is provided by a separate power adapter for each device. also... somthign i didnt know... Networking over FireWire FireWire can be used for ad-hoc (terminals only, no routers) computer networks. Specifically, RFC 2734 specifies how to run IPv4 over the FireWire interface, and RFC 3146 specifies how to run IPv6. Mac OS X, Linux, FreeBSD, and Windows XP include support for networking over FireWire. A network can be set up between two computers using a single standard FireWire cable, or by multiple computers through use of a hub. This is similar to Ethernet networks with the major differences being transfer speed, wire length and that standard Firewire cables can be used for point-to-point communication. Note that this feature is not supported in Windows Vista.[14] The PlayStation 2 console had an iLink-branded 1394 connector. This was used for networking until the release of an ethernet adapter late in the console's lifespan, but was poorly supported by software. |

You can do this with them. The "X" means the second connector on the second drive is not used. +----------+ Computer ----------| Firewire | | Drive | +---| #1 | | +----------+ | | +----------+ +---| Firewire | | Drive | X----| #2 | +----------+ My experience suggests the daisy chain connectors are "active buffered". If my computer talks to drive #1, I get higher bandwidth than drive #2. There seems to be a bit of a bottleneck, for packets that go in and out of drive #1, on their way to #2. YMMV. I don't have a third enclosure, to daisy chain a third one :-) Paul |

Daisychaining more firewire devices. Firewire is meant to connect from device to device instead of a central hub like USB. |
