Although I found a work-around, I was wondering if there is a solution. I am running this on a E520 Lenovo laptop using an NEC chip USB 3.0 ExpressCard adapter. Windows 7 64-bit.
First, the drive cannot be ejected via the "Safely Remove Hardware..." notification icon. However, I do have the default drive policy, "Quick removal" checked in the device manager, so in theory I could simply unplug it, but have been afraid to do so since it can't be ejected like other drives.
Second, since the drive can't be ejected, if one puts the laptop to sleep and then disconnects the drive, the drive persists in the "My Computer" list when the laptop is reawakened. Worse, if one plugs in a new drive, not the Seagate, it can accidentally be identified as the ghost Seagate drive and the OS actually allows one to to try and read and write from the misidentified drive. The operations so far don't seem to be able to complete however, and I haven't seen any permanent damage caused by it, although there are lots of time-outs and error messages.
As a result I nearly had a heart attack when this first happened since I had plugged a *different* hard drive in prior to waking up the laptop, and to my surprise, a 1.5 Tb generic drive was then being identified as the 3Tb Seagate Expansion Drive! Before I realized this, I had attempted to transfer some files to the misidentified drive, and the copy dialog appeared to be transfering the files, but eventually started spewing error messages. That flurry of error messages eventually got me looking at "My Computer", and that is when I realized the drive list was completely wrong as a result of the weird behavior of the Seagate Expansion Drive.
The work-around I found to safely disconnect the Seagate Expansion Drive was to shut down the computer fully and then disconnect the drive. This makes using the Expansion Drive with a laptop a real pain-in-the-neck since most of the time I put the laptop to sleep upon disconnecting a drive. I can't do that with Seagate's ED since it becomes a ghost drive.
(1) Is there a solution to being able to make the Seagate ED hot-pluggable? "Quick removal" is checked in drive properties, but I don't want to test this on a drive with live data, esp. since it prohibits "Safely remove hardware and Eject Media" from executing.
(2) How can one prevent the Seagate drive from persisting in the My Computer list when it's not even plugged in? (it happens when I unplug the Expansion Drive after putting the laptop to sleep)
