Hey Everyone, I have recently set up my new imac and im having a bit of a problem with Time Machine. I have my imac wired to a belkin router that is attached to a Western Digital MyBook World edition to work with time machine. Ive reset the NAS back to factory setting and cleared it and when ever I set the time machine to create a back up (currently about 80GB) it gets to somewhere between 75 and 79GB done and comes up with a message saying something like calculating changes and then whenever I try to back up again after this the back ups are rediculously slow. I mean like after 5 minutes it might have done 10KB, YES KB!!! Also, strangely, whenever I start these back ups it says something like preparing xxx items and it reaches about 40,000 items before it starts backing up and then only wants to back up about 15MB or something small which obviously cant be right. time machine worked fine before on my MBP Any ideas?
