I'm really hoping someone can help me with this. I have a TB drive that until recently has resided on my PC which streams/syncs to my AppleTV. Well, I've finally decided to stop copying everything over to it there and just place it on the network. I have an AEBS with a 500 GB drive already attached which is running seamlessly as a Time Machine Drive. I went and bought a tiny little USB powered hub and connected it this weekend. The Time Machine drive is connected through it now and still works perfectly, but whenever I connect the TB drive and try to mount it so I can alias all the files into my MBP's iTunes, it kills the AEBS and I have to restart my whole setup to get the internet back. I tried connecting the TB straight through to the AEBS, but that didn't do it either, so I know the problem isn't the hub. To clarify, Finder shows the two drives under the AEBS, but as soon as I try to connect to the TB drive the network connection drops across the whole network. I have no idea what would be doing this and would be devastated if it turns out that the TB drive is just too much, but I seriously doubt that's the issue. My only possible idea is that the Time Machine drive is HFS and the TB drive that was connected to my PC is still formatted as FAT32. Does anyone know if this could be the root of the problem? I'd hate to have to wipe it and reformat and then copy all my files over from a backup drive, but I will if it's the only way. Please don't jump to assumptions though and tell me this is what to do unless you know for sure or have had experience with this kind of problem. Someone...help? Please.
