So don't wipe any drives until you know which flavour you have. Some of the technical stuff starts around post 219 of the Hot Deals thread: What we know so far is that the firmware to run these may be either in the unit or on the hard based on the original configuration.
So if you have questions or solutions on how to set these things up, configure them, mod them or even troubleshoot them please post in this thread. There were subtle changes in hardware and software as this process happened. Part of the confusion comes from the fact that these were initially an Iomega product, which was then bought out by EMC, which Lenovo later acquired. A number of us have bought or per-ordered these based on this thread in the Hot Deals forum: As the orders trickle in we are quickly learning there are many nuances to these units and that the information available on the web is scattered around.
I'm starting this thread on the Lenovo Ix2 and Ix4 NAS boxes.
