Chaining vs. direct connect...
Authored by: robg on Jan 16, '03 01:25:34PM

I .think. this problem only occurs with chained devices, ie Computer -> Device 1 -> Device 2. Remove Device 2's cable and Device 1 may no longer work. I experienced this while travelling with a 20gb FW drive and a FW camera; when I disconnected the camera and left the cable attached, the drive wasn't happy.

But at home, I leave the camera cable plugged directly into the back of the Mac all the time, and have no trouble...

me too, no problem with my always attached ipod cable.

the passthrough ports on firewire drives are known to be somewhat flaky, so it doesn't surprise me that they couldn't handle a cable without an attached device.

lets stay away from the word "terminate" as its old SCSI terminology. (I'm very sure there's no such thing as a terminated firewire cable)

FireWire "termination" exists. It is not outdated SCSI terminology. The difference here is that it's done /automatically/ in FireWire, all the time. The extra two pins on your FW port (vs your PC friends' crappy 4-pin FW ports) are for termination power.

Yes, you're supposed to disconnect the cable from the FireWire controller first (read: TEH COMPUTAR!!1); no, there is nothing special about the cable that comes with the iPod; and no, not all chain pass-through ports suck. As a matter of fact, the ports on my LaCie FireWire drive kick much ass.

I am looking at the back of my Qksilver 800 and I have one wired (not connected) and another (chained to two CDRs and a DVDRAM). Never have bootup or corruption issues.
Might be isolated incident.

Then again, I have all Granite Digital FW cables with the bright green LED.

"Remember-don't ever force the FW cable into the slot. Someone one did and friend their board and drive" +20volts can be bad...

Those 2 pins you see there are the 12V power coming from the CPU that charges your ipod and keeps bus powered devices running. Firewire does not need "termination" in the sense of scsi because it is a serial- based interface.
