I have an external hard drive that is not showing up in device manager. Can you help?
I have a Seagate Backup Plus external/portable drive. Purchased August 2013. Working one day; not working the next. If looking at task manager it shows its running however it does not show up I device manager.
It could be the USB panel of the drive got faulty or the USB cable. Try to replace the USB cable first see what happens.
And when the drive is working try to check it with : http://crystalmark.info/software/CrystalDiskInfo/index-e.html
