Hey, i have had the new 21.5" iMac for over 2 weeks now and have not found a hardrive for time machine backup. One i dont know what to be looking for. I am not willing to spend over 90-100£ on it. I have found these two, can any reccomend any from the two or any others? When referring to the hardrives can you refer to this one as 1: item.mobileweb.ebay.co.uk/viewitem?itemId=110982392612&siteId=3&isClassified=false And this one as 2: www.amazon.co.uk/gp/aw/d/B0084LZI9U/ref=redir_mdp_mobile?creative=22206&creativeASIN=B0084LZI9U&linkCode=asn&ref_=asc_df_B0084LZI9U11067801&smid=A3P5ROKL5A1OLE&tag=googlecouk06-21 I have the 1TB iMac. And on my harddrive i have lots of valuable courseworks and a few games of course so i dont want t coursework to go missing. I would really appreciate your input.
