Iomega Prestige 320 GB USB 2.0 Portable External Hard Drive 34342
$114.99
Perfect machine. Small, quiet, effective. A very efficient purchase and hard drive overall. I would recommend this to absolutely anybody. Works like a charm, comes with a USB cable and an extra connection, I suppose in case you need more power. So far not needed though. I am very happy.

No brainer installation, but if you need help, WD is there for you on the internet. Item was well protected for shipping.

plugged this into my HTPC build as was looking for a large, yet quiet and cool HD. This HD is perfect and performs exactly as I had hoped. The energy savings is added bonus.

Seagate FreeAgent Desk 1 TB USB 2.0 External Hard Drive ST310005FDA2E1-RK (Silver)
$139.99
I have installed the 64-bit updates from the Seagate Website but I still get blue screen errors every time I plug it in. Apparently Vista Ultimate and Seagate are incompatible. I will continue troubleshooting and attempting to fix it. If that works, I will update the review... If not, I will not buy another one of these paperweights and will seek a refund and more.
