I bought one of these. The listing speaks of the hard drive LED glowing red. I have confirmed that these devices do not have a hard drive LED, there is not even a cable for it. Strangely, there is a reset cable. I don't understand why it has a reset cable as there is no reset button. You should also take this button with you, as it cannot be removed from the computer without opening the case to unhook it. Another thing is that it works as intended.
