"Well it came fault it the first one that I have had off them that was damaged. I reported the fault and got told to send it back. What I never liked is that I have ordered many many many thousands of pounds of items from Amazon over the years any only had to return about 4 things I think. So they are basically calling me a lier which I did not like over a £25plus harddrive. I don't leave the house and I only shop online so it's pointless asking me to send it back so just chucked it in the corner it's no good with bad block errors. I understand some people my lie to get a free item but Amazon should understand that if a person never really send much back and as been customer for many years it's safe to say his not going to lie about a £25 plus harddrive. Other then that from my past experiences on working harddrives this sells the harddrive are good and cheap. I am giving it 3 stars only because this one I ordered did not work not the reset that I have brought from them."
