External hard drive cables rarely fail unless they get the same sort of abuse. USB cables can fail after prolonged use, though this is more likely to happen to the Micro USB cables used with mobile phones. EHDs that have their own power supplies tend to work more reliably. This can be a problem if the PC’s motherboard does not supply enough power to the USB port you are using or if the drive is plugged into a non-powered hub. Some external hard drives draw their power from the USB port and they may not get enough. The port, the connecting cable, the power supply and the external hard drive (EHD) can all suffer from physical and/or electrical faults. Thank you to all of you guys who have tried to help me with this.Lots of things can go wrong. When I heard tried to verifyDisk and repairDisk a few days ago it had not worked but somehow with this sequence it was able to repair the partition map Since I've tried pretty much every terminal line under the sun, I think the key was the sequence in which this worked, which was: mount -t /dev/disk3

I recently bought a 4 TB naked (no enclosure) external hard drive that I mount via a Newer Tech dock (the ones where you insert the naked drive like bread in a toaster) and is connected to my MacBook pro via FireWire 800.Ībout a month later I wanted to use the drive and it would not mount.ĭisk Utility reports that it is "Not Mounted".
