Installing a Zip drive causes the zip disk to constantly try to load. Can't eject it when it does this. If I hook it up to my G4 via its power plug, it works fine.

A similar issue with the Imation SuperDisk drive. If it's powered by my G4, it works fine. When I have it plugged into the GDock, it acts like it can't quite load the disk.

This is with just the power connected, not the data cable. So I'm wondering if this is a power issue. I'll try taking pictures of it, maybe someone can help me identify what part could be the problem?
