I use an external HDD on a machine. Lately, the hdd has been dropping the USB connection (Windows plays the disconnect/reconnect sounds, then the hdd device goes away for half a second, and comes back).
At first I blamed the HDD (it's new, "Western Digital" if that means anything to you (they all fail eventually)). Suddenly one day the HDD completely disappeared from the machine (it wouldn't show up).
Naturally I panicked and am now mirroring that hdd's data on another hdd, using another machine.
Funny thing is, the hdd in question works fine on this other machine. it doesn't seem to be having any issues.
How can I diagnose if there is a problem or not with the USB ports in my machine? It has 8 of them and I can't remember which one the hdd was plugged into when it was failing --=
