I just got my 15' MacBook Pro refurbished (by Apple), and everything is working well except my USB ports. My USB keys appear for 30 seconds to as much as 2 minutes before disappearing from eveywhere, my desktop, finder and disk utility.  I have a 1 TB WD passport for mac that also has the same problem, but can stay on the desktop and copy files for around 10 minutes. Then error -36 shows up, the hard drive disappears from the desktop and finder, but only appears in disk utility. It is powered as well, The light is currently flashing indicating it's receiving power as I am typing this. But still, no way i can copy anyhting onto it.


I have searched and searched for the solution to this problem, I have tried using apple script to find "invisible hard drives." and that doesn't work either.

On my windows partition in bootcamp, all usb keys work perfectly fine.


Is it because the USB ports are out of energy and dying? If so, should the refurbishment have covered that and replaced them? (Note: refurbishment included everything from my Keysboard to my battery to my Optical drive and cable optical drive flex)

Is there anything I can do to fix this problem on my own?


Any help I can get would be greatly appreciated.

MacBook Pro, OS X Mountain Lion (10.8.2)
