Yes, this is what is causing me anxiety. You doubt it is the hdd and yet that is the part that they have shipped to be replaced . So if it isn't the hdd then that means that I will lose everything for nothing, such as my bookmarks for instance. I could buy an external drive before they come out but I don't know how to transfer from the computer to the external harddrive. Once I tried it and there was nothing on the external harddrive . What should I do ? Should I just cancel the service call and wait till it gets worse before doing anything ? Should I let the technician come out but I am not happy about replacing the harddrive, especially since you say that it is not what is causing the problem in the first place ?
