The first review was written before this unit was available, and the second couldn't get in touch with tech support, so be wary of all those stars.I purchased the unit and it would not install on Win98SE no matter what I did (I also couldn't get through to a support rep)It was pointed out to me that the blue and white color scheme of the Maxtor are the dated colors of the Imac, it makes one wonder just how old the plans and tech for this unit are...Finally after 48 hours of configuring, I got it up and running but it was much too slow at backing up media so I exchanged it for the Seagate 160 External, which is nearly perfect in comparison to the Maxtor and just what I wanted in an external drive
