Hello folks, I have an issue i'm hoping someone can help with. iMac 24" 2.93 4850 connected to Iomega ultramax 640Gb external HDD via Firewire 800, this is in turn daisy chained to an epson r1800 printer via firewire 400. Issue is that my drive either disconnects or becomes unresponsive after a short while (around 20mins). I have tried disonnecting the printer to see if that is causing the problem but the 'dismounting' still occurs when there is nothing else connected! I have done all the logical searching for solutions i can think of, no joy, so here i am at the trusty MR resource. Thanks in advance for any light shed.
