I have the setup below, with a 3tb seagate connected through FW800. With all the weird errors that happened during backup of my pc, I've decided to return it and use the 2.5" drives that I have instead. On two ocassions the erase has failed, both with the 1 pass through disk utility on 10.7.3. Are there any other options besides this? I've searched but on the oct 2011 thread, there was no solution.
