I am unable to see or access my passport external hard drive….. On my Mac air-book. I was able to access last week. When plugged in to a port (and I’ve tried both sides) it is running…the light on the drive is on and it’s running, but I can’t see it and it will not load any “previous” files. I’ve opened and looked for it on disc utility as well… it’s not there. I’ve rebooted…. I’ve unplugged, replugged…. I’ve tried with and without power attached. I’ve tried with and without wifi. I’ve completed an SMC reset…. No luck. It does not show up.
Now the odd part - If I plug it into my wife’s macbook air – it’s fine. I can see it, access files, etc. etc. So the issue is only on my computer? What could be wrong?
