Pros: Seems to work well and transfer quite quickly on USB or Firewire. Windows recognizes it right away when you turn it on.

Cons: Power cord pulls out too easily. Software is very unreliuable. If the "back up" button stays lit all the time. If I tap the case the Retrospect software launches. I think the button is stuck or something. When I burn dvd files that I store on the external hd, retrospect software launches and causes the system to freeze up, ruining a 50 cent disc in the process.

Overall Review: The hard drive is good but the software is terrible. you will need to buy new back up software if you buy this external hd.All in all Im still happy with the HD, minus the software issues.
