Maching time keeps failing - bought new hard drive and still the same problem

I'm on a mac 27 inches, El Captain 10.11.2 upgrade

Not had a problem for years and then suddenly about a month or two before, he started to do all the time. Got a mybook 2 TB for mac for Christmas - same problem. Works perfectly for hours/days at a time, and then fails again. Don't know what to do!

I know it sounds weird, but I would like to start by making sure that your Mac hard drive is correct. Demarrer start on the recovery environment, run disk utility and perform first aid on your hard drive. You can also perform a boot secured, which does essentially the same thing.

I also saw problems with USB devices that appear only on a specific USB port. Try changing ports.

The external drive is new does not mean that it is not defective. Perform first aid on the external hard drive and reformat. Better still, try another drive altogether to eliminate the drive as the source of the problem.
