I don't think your problem is related to what this thread is about - your symptoms don't match.
The G-Technology website's support area has some ideas you can use. First off, they have a caution to only use the USB cable that came with the drive. The reason given is "other" cables may not carry power very well, causing your dirive to become unstable (which could be what your observing).
We recommend using only the included USB cable with your drive. USB bus power is rather limited, so lower quality cables can result in unreliable power to the drive. This can result in poor performance, clicking and other noise, or complete failure to detect the drive on your system. There can also be similar issues with using longer USB cables, especially those longer than 3ft/1M.
They also have a troubleshooting guide for MAC: http://www.g-technology.com/kbase/users/kb.php?id=54&category_id=22
I think your likely to get more (maybe better) help in their online support forum:
I did a search for "eject" and over the last few months there have been a lot of postings from people experiencing the same problem as you.
I think its time to call G-Tech service and ask for an RMA: +1-888-426-5214.
Just a reminder to others that one of the first steps is to GOOGLE your drrive and/or poke around the Manufacturers support site to see if OTHERS have the same problem. Doing that can save you a lot of time.

OMG! I am so full of .... my eyes should be BROWN!
I just dug out my old post about my USB3 iNeo tests - and it FAILED!!!!
I "got it to work" by moving it over to a Windoze computer.....
I also found my post of the known-to-fail USB chips:
The iNeo post is a few before it.
This would suggest some truth to the theory ofa USB 3 related issue. Although, note it was only LARGE files that failed.

I'm aware of the cable issue and use only the one that came with the drive. A number of the G-Tech forum posts suggest repairing permissions, which is what I'm doing with OnyX, along with the other maintenance routines (repairing permissions via Disk Utility didn't help).
I may try calling G-Tech. However, I'm pessimistic it will help. Many people in the Apple Forum threads got replacement drives and had the problem recur, and the problem is happening with so many different brands.
There's obviously a software component to whatever my problem is. Something in the hardware is ultra-sensitive to the ever-changing state of the operating system, particularly when the drive has been disconnected for a bit.
But thank you for your help and all of the time you've spent.

It looks like Lacie released a USB 3 driver for lacie drives that works on some kext files and addresses issues related to mac osx, but that someone has patched the file to work on other manufacturer id'd drives? I don't have snow leopard so I can't install multibeast. Can someone look into this?
Here's a link:

Sorry for the premature post. It looks like people are having mixed results with the lacie drivers and the patched lacie drivers, and they are primarily for people who buy their usb 3 pcie cards. Ug. I'm going to keep hunting looking for open source softtware for increased usb 3 compatibility.

I did the research and found the best option is to get a firewire dock or get super USB. Until Mac and Intel make the upgrade to USB 3.0, it will be more hassel then it's worth. That's just my opionion, but I have had a replacement firewire dock, replacing the USB 3.0, for 3 weeks and no ejecting.

"Steve Jobs made a point of saying that No Intel support was a big problem for Apple when it came to USB 3.0. With Intel planning USB 3.0 CPUs for early 2012, there’s just no way they’ll jump ship to a third-party manufacturer instead of just waiting it out." This was a excerpt from an article from "Cult of Mac"

Thunderbolt is much faster, much more efficient. USB has so much overhead that its nearly impossible to get near the max speed of the bus.
This is kinda off topic for this thread guys.
Read more about USB and Thunderbolt on wikipedia:
What I worry about is the cost of adding Thunderbolt to new designs. USB was supposed to be a temporary interface, but it stuck around and is everywhere because it is very inexpensive to add it to a new design. Heck, there is an all-in-one chip you can buy to add a USB interface to your own home electronics projects!
If your trying to get the best speed for external drives, FW is the cost-effective way to go. eSATA is faster, and a lot of places are selling off their stock of eSATA cards so I say snap them up!
However, the dirty secret is your hard drive likely cannot handle sustained data transfers faster than about USB 1.1 or 2.0, so why bother?
