why is my external HD bay less effective at reading a failing hard drive?
I know my backup hard drive is starting to fail, because the external USB bay sometimes can't access it; and when it does, I sometimes (not always) hear the characteristic ticking . Until I can get around to ordering a replacement, I knew a trick that often helps: put the failing hard drive in my laptop's internal bay and run the main hard drive from the external bay. The internal bay accessed the drive more easily. I just wondered why an external bay has more trouble. I vaguely supposed it has to do with the USB connection having some inherent limitations. Can anyone explain it better?
