Here's the scoop. I've got an old 2011 Acomdata External HDD that I haven't booted up in a few months that is not recognized by my computer. And no, I don't even get a "USB has malfunctioned" error message, nor can I see it in Device Manager or Disk Management. I can't even view it via the obscure cmd method. As for the product itself... turns on, lights up. Does not make any weird sounds that indicate the drive is toast. I have run out of options at this point. I was thinking it needed more power, so I thought about connecting it with a spare dual USB cable to give it more juice. Anyone have any ideas? Or am I screwed?
