II am currently using a 2.5" 40GB USB 2.0 Kanguru Portable HD. This device has worked well. However, I am seeking a replacement . Requirements. 80GB, USB 2.0 (logic and power off the USB port) and most importantly the device comes in an industrial strength case where the drive is well padded from shocks. Maybe put another way, what is the lastest and greatest gear out there in portable HD's. Any suggestions would be appreciated. Thanks.
