Why is my external hard drive not working?

Peter Herring May 31, 2013

My hard drive is formatted for Mac. When it left St Louis it was working. When it arrived here it is not working. When I plug it in, it shows a green LED. Then it blinks red 6 times then goes back to green.

Any help is greatly appreciated!

      DiskWarrior is an superb program, but all it does it rebuild the folders on a Macintosh drive. It does not deal with the hardware or even with the partitions. Since Peter does not say that the system is reporting an error on disc, DiskWarrior will not help.

    Look up the blink/error code in your manual.

    Kindly mention your HDD brand and model number as External hard drive light/LED behavior varies from model to model. However, I am enclosing Seagate external HDD some basic troubleshooting checks (it is mentioned for Windows, but relevant for Macintosh too and replace the Macintosh equivalent steps instead of Windows).
