Alan, I have an Intel iMac (24" Mid 2007) running 10.6.2. Earlier this day I was moving files from an Iomega 500 GB External Hard Disk Drive (EHDD) via the iMac's FireWire (FW) 800 port to another EHDD, a 1.5 TB Western Digital My Book, via the iMac's FW 400 port and copying a video from a camcorder (iMovie) via FW 400 connected to the EHDD connected to the iMac's FW 400 port to the iMac's internal HDD.
Iomega 500 GB EHDD#1 -> iMac FW 800 port -> iMac FW 400 port -> 1.5 TB Western Digital My Book EHDD#2 Camcorder -> 1.5 TB Western Digital My Book EHDD#2 -> iMac FW 400 port -> internal HDD About half way thru everything, the iMac froze and I had to power down and power up again. After I did that, it seems that the FW 400 port does not seem to work correctly. The FW 800 port still works and I can connect the external FW 400 HDD to the iMac via the external FW 800 HDD and I could still use the FW400 port to copy the video from the camcorder. But the 1.5 TB Western Digital My Book doesn't work via USB anymore either. The System Profiler reports lots of FW info if ONLY the FW 800 EHDD is connected and when an external FW 400 HDD is connected, it takes a minute to report back only that the maximum speed is 800 bps. Until I spotted your post, I thought the problem was with my iMac since I can use the 1.5 TB Western Digital My Book on other Macs' 400 FW ports. I haven't tried the 1.5 TB Western Digital My Book's USB port with other computers. My question is, if it isn't the WD HDD, what are the various things I can try to reset to try to recover my FW 400 port? Bringing it in to the Apple store is something I want to do last, even though I have another 11 months of Apple Care coverage left.
