It could just well be that the act of changing the cable itself (e.g. by reseating connectors) has brought about the change. The device sockets themselves are mechanically quite exposed. > It may sound more than half way off to you, > but it is physically possible and it has been actually demonstrated > that "they" have been hacking into computers through the power supply > lines . . . I hope this is tongue-in-cheek. Yes, I know about proof of concept things in this area (more exfiltration than intrusion, though [1]), but those kinds of attacks are so expensive that you'd have to be a rather important person for them to carry their weight. I'd rather worry about the javascript my browser is downloading from All Of The Internet and executing in my computer. Cheers [1] Yes, I also know about glitching [2]. Targets are typically much simpler devices than your computer or your external disk enclosure. Besides, you'd notice if one of those were rebooting hundreds of times a minute until the hackers succeeded.
