In all versions of Windows (do you have Windows or a Mac?) TWEAKUI (google.com please) can be used to see if you have hidden drive letters.
Or someone returned one from this discussion.
i bought this maxtor 3100 external hard drive. there is nothing to install.
so i just plug the power cord, and plug the usb thing.
however, my laptop tells me that it is not recognized.
i tried several times, turned off the laptop and restart again. still nothing happened.
so is there something wrong with the hard drive or something else? according to its web site, there is nothing to install.
