the plugable usb 3 hdd docking station i have doesn’t work well at all. i have it plugged into a plugable usb 3 card and when it feels like it, it will mount the hard drive which isn’t most of the time. a blinking green light on the device (with the drive unavailable to the operating system) usually seems to indicate some sort of difficulty accessing the drive. i went ahead and swapped the usb 3 cord for a usb 2 cord and plugged that directly onto the motherboard to no avail. however, when i go ahead and use another brand usb 2 docking station connected to either the plugable usb 3 card or to the motherboard, it works flawlessly (with the same drive). before you ask, i am using the latest drivers for the usb 3 card as well as the latest firmware per your site for the docking station. the os is 64 bit vista.
ps: when the drive manages to mount (via the plugable docking station) which is rarely, i continuous/brief freezups on my mouse pointer as i move it around which makes it hard to get anything productive done. if the device manages to appear in windows for an extended period of time, it will eventually disconnect itself (as when ejecting a drive) and then reconnect later if left on.
