They were nice enough to refund my money and shipping. Tossed the HDD, it was bad.

I grabbed an old iBook 30GB drive. I partitioned and formatted it on my PowerMac. I stuck it into the Outbound and it booted fine with no screen artifacts. It detected the HDD and asked if I wanted to format it (which I had already done.) Unfortunately, it appears to get stuck at that point. It'll start the format process and not do anything. :\

I set it to 400MBs. I found a thread on a different site that said the largest they shipped with was 80MBs, and he wished someone could hack the firmware to allow for bigger drives. I'm going to try partitioning it to under 80MBs an see if that works.
