Your backup drive is in a weird state. You'll want to power off your Mac and the drive, power back up and try again.
Are you using a hub? There seem to be a lot of dries connected...at least 5, from what I can tell.

Hubs, in general, are a problem with high speed drives. Not all of them, but most. I'd avoid using them.
"Exact same problem" would be weird post-powering *everything* off. Or are you saying it didn't work "overnight"? If you could, please send the log using the "Send to shirt pocket" Button so I can get all the details in there, and we'll continue in email.

I followed your instructions: I shut down the iMac and turned off the drive last night. This morning, I powered up the iMac, turned on the backup drive (which is connected directly to the iMac), attempted to do a backup, and received the same exact error message.
