Back up any important data to an external drive before they arrive to be safe but I doubt its the hdd.
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 ?
