Hi. I just did this test in my macbook pro 2.8Ghz with Techtool Pro 5. In the picture you can see the results. If you can notice, the SPIN RETRY COUNT parameter is the only one that is low. I dont really know if this is a problem. It passed the test at least, but Im not sure if this is affecting my laptop. Does any one know what is this? should I worry? Should I take it to an apple store. Any suggestions? Thanks! pd: I forgot to write that Ive been experiencing some freezes of 1 or 2 seconds. Im for example scrolling a window in any browser or even the finder and it freezes for just that time, its nothing but is annoying. Also when Im transfering a file to the trashcan it takes the same time. My macbook is pretty new, It just has 2 months old. Im a bit worried as its an expensive laptop. Since the macbook is new , yesterday I did a full re-installation of the software (Snow leopard) but it still behaving a bit slow.
