Summary: this produce is not the 750gb as advertised. it is 32gb. why i do not know. i just know used it 2 months after i payed for it. i doubt if it can be returned.I went to every website listed in the paperwork from the company. ALL WEBSITES ARE CLOSED! THE USER MANUAL MAKES NO CLAIMS FOR SIZE OF GIGA BITES, ONLY THE 2.5 INCH OF THE UNIT. THIS IS A COMPLETELY FAKE COMPANY.
Summary: I used this hard drive a couple times. One day, I went to use it and all of my files were gone. It was completely blank. That is the opposite of what I want an external hard drive to do. I didn't erase it nor did I reformat it to make my files disappear. I would choose a different hard drive.
Summary: This hard drive worked fine for USB 2.0, but does not work for USB 3.0. I am running Win7 SP1. The USB 3.0 port works fine for two other drives, so I am assuming the USB 3.0 port is fine and it is a problem with either the drive or the connecting cable.
