I searched the Forum and found no issue as I am writing about. Mac User. I just purchased a LaCie d2 USB 3.0 Thunderbolt Series 4TB External Hard Drive (9000303) and intended to save the LaCie Setup Assistant and Readme.txt files before formatting, however I failed to do so. Does anyone have recent copies of these files you would be willing to send to me. I know it might seem strange to some I wish to have these files, but I do and I am not interested in any of the alternative downloads available on the LaCie site. If you have these files and are willing to share them with me, please private message me so I can send you my email address. Thank you very much!
