Do you only have a 9-pin to 9-pin cable, or also a 9-pin to 6-pin cable that you could test? I take it that you cannot dualboot into OS X on the iMac, do you? Otherwise you certainly would have tested whether or not OS X discovers the drive. > > Processor: Intel Core 2 Duo, T7300 @ 2.00 GHz x 2 > > OS: Linux Mint 17.2 Cinnamon 64-bit > > Kernel: 3.13.0-38-generic [...] > > Make: WD (My Book Studio) [...] > > $ dmesg | grep -e 1394 -e firewire > > [ 0.116545] ACPI: SSDT 0xFFFF8801394A4840 000085 (v01 APPLE Cpu1Cst 00003000 INTL 20061109) > > [ 2.244113] firewire_ohci 0000:03:00.0: added OHCI v1.10 device as card 0, 8 IR + 8 IT contexts, quirks 0x10, physUB > > [ 2.744192] firewire_core 0000:03:00.0: created device fw0: GUID 001f5bfffe0919bc, S800 > > [ 367.700992] firewire_ohci 0000:03:00.0: removed fw-ohci device > > [ 456.312119] firewire_ohci 0000:03:00.0: added OHCI v1.10 device as card 0, 8 IR + 8 IT contexts, quirks 0x10, physUB > > [ 456.812335] firewire_core 0000:03:00.0: created device fw0: GUID 001f5bfffe0919bc, S800 > > > > $ lspci [...] > > 03:00.0 FireWire (IEEE 1394): LSI Corporation FW643 [TrueFire] PCIe 1394b Controller (rev 06) [...] There were problem reports about iMacs with FW643 rev 06 in the past, but these issues have supposedly been fixed by adding the "quirks 0x10" bit in firewire-ohci for these controllers. Please run the following commands: $ sudo modprobe -r firewire-ohci $ sudo modprobe firewire-ohci debug=3 $ logger "connecting disk" (now switch on and connect the disk) (wait a minute) (disconnect and switch off the disk) $ logger "disconnected, connecting once more" (connect the disk, then switch it on) (wait a minute) (switch off the disk, disconnect it) $ logger "switched off disk, connecting macbook" (connect the MacBook to the iMac via FireWire while the MacBook is running Linux or OS X) (wait a minute) (disconnect the MacBook) $ sudo cat /var/log/messages > messages_copy.txt This assumes that Mint 17.2 is configured such that kernel messages are logged into /var/log/messages. If it isn't, then just inspect the output of "dmesg" instead. "dmesg" does not contain the user messages from the "logger" command though. While you have the MacBook attached to the iMac, also look out for kernel messages on the MacBook where it discovers the iMac as a FireWire node (or shows it in OS X's system profiler). In the worst case you don't get any messages at all, which would mean that the iMac's FireWire port is dead. -- Stefan Richter -=====-===== =-== ----= http://arcgraph.de/sr/ |
