My LaCie Firewire 800 hard drive, connected to my Macbook Pro via Thunderbolt Cinema Display port, disconnects after sleep

Question

I have a LaCie RAID Quadra hard drive (two disks in a case set to a redundant array) which for all intents and purporses appears as a normal hard drive to my mac.
When connected directly via FW800 to my Macbook Pro (2011, with thunderbolt port), it works perfectly.
For the sake of convenience, and since I am using it only at home as my Time Machine drive, I connected it to the FW800 port on my Thunderbolt Cinema Display.  The display works perfectly in every way up until now.
When connected, the drive works great.  However, when I put the machine to sleep, upon awakening it, I receive the "Disk improperly ejected" error immediately upon the screen coming up.  
The drive is set to Auto mode which has always worked fine in the past; putting the drive to sleep when the computer is asleep, etc.
So, I only receive the disk ejected error when it's plugged into the Cinema Display; not when directly plugged into the MBP.
I have the 1.1 firmware update applied to the monitor.
Any ideas?  I appreciate it.

My desktop has two FireWire ports. In the first one I had my webcam plugged in. In the second one, the External Hard Drive. I unplugged the camera and used the first port for my External HDrive and now it works! So it seems the problem is a hardware problem with the port.
I'd check to see if the problem returns when you plug the camera back into the second port, or if the drive works in the original port when the camera is not connected.
Edit: Maybe you unplugged the problem, when you unplugged the camera?
