Either theres a bug in the drive electronics, or its just so underpowered that requesting that SMART data while the drive is quite busy reading/writing will stall out the drive for up to a couple minutes at a time. My feet have been freezing in the southern parts of AZ for the past month; overnight temps were in the 30s and 40s. We have struggled to find the right system to use on the Apple platform that would attach to all of our hardware. They fit perfectly and are SO comfortable. I am purchasing shoe clips to further dress them up. We have worn these for hours on end, they work well and are comfortable. But oh my gosh. All the while getting to listen to my music and podcasts at a decent sound quality. About the middle of my foot on the outer side is rubbing against the hard cork. I guess I will be going back to my old crocs for cushion.
