I have an external hard drive that's my working drive for photo work. It's a 7200rpm Seagate Drive I'm using a brand-new rMBP 15in. I've had some issues with Mavericks restarting with external drives plugged in. Today, I was rendering some photos, somehow my drive got ejected, and now it get this error message whenever I plug it it: "USB Devices Disabled Unplug the device using too much power to re-enable USB devices." I've tried the drive in different enclosures, with different cords and on difference macs. I've tried plugging it into two USB slots. Still the same thing. Sometimes nothing happens at all, other times the error message pops up instantaneously when plugging it in and other times it takes several moments before the error message popped up. The drive is new (just over a year) and it's not making any funny sounds and other drives work. I really need this drive to not be dead. I have all the files back-uped, but I spent all day doing reorganizing and re-exporting my photo library and I really don't want to have to do that again. Thanks for any help you can give me. UPDATE: It seems one of the USB ports is no longer working either.
