Hi, I've had a search on the forums as well as Googling the issue but cant seem to find anyone with the same issue as my grandfathers iMac 7,1 As the title says after seeing his iMac taking an unusually long time to open simple things like system preferences, whereby it takes a good 5 seconds to appear in the dock, then a short while longer to open I decided to do a speed test on the hard drive and got a max of 2.5Mbps write using Blackmagic. I didn't even wait till the end of the test it was taking that long. I was under the impression it should be around 60, or at least considerably more than the reading given. The strange thing is he uses Final Cut Pro 7 and only complains of the occasional freeze. I left it doing a disk check before I had to leave and don't know the results yet. So what do you think? Is the drive on its way out or would an OS reinstall help out? It is a work machine so I don't want to leave it too late! Luckily I set up Time Machine from the beginning.
