everyonewantsausername Posted March 14, 2017 Share Posted March 14, 2017 CPU | Intel core i7 6700 3.4GhzMobo | Gigabyte H170-D3hpRam | Corsair Vengeance 16GB (2x8GB) 2133MhzGPU | Galax GTX970 4GBSSD | Samsung 850 Evo 500GBPSU | Thermaltake 600wOS | 10.11.6I initially thought this issue was a blown port and while it still could be hardware I've noticed something very odd.Two days ago I was using a USB 3.0 portable drive doing some colour grading in Da Vinci resolve. Quite suddenly, the mouse stopped working and then a couple of seconds later the system reset itself. I have no idea what happened but when the system rebooted a message popped up and for a tense few seconds I was worried the drive was ruined. The message said something like 'drive connected to mac but does not have power' or something along those lines but specifically indicating that I should plug the device in to a port that has power.This was the same port the drive was plugged in to when the reset happened and so I unplugged it and moved it to the port above and it worked. I was curious about the issue today and didn't have any critical work to do so I had a test with another bus powered drive that also previously worked fine. This one also had not encountered any dodginess like the sudden system reset either. I plugged it in to the port that I knew had caused issue and received the same message. I plugged it in to the port immediately adjacent and also received the same message. The thing is the drive is spinning so it *is* receiving power and the fact that it's giving me that message suggested to me that is registering on at least some level with OSx. I've also had a look in IOregistryexplorer and can actually see that the drive that supposedly has now power is listed in the IOUSB section while it is currently plugged in to the malfunctioning port. On top of that the LED light on the hard drive functions too.Anyone know what I should do? Link to comment Share on other sites More sharing options...
