I'm worried of the same error happening again with the new drive, but let me know what is best to do. Follow the procedure I provided. This is the proper way to prepare a new, bare drive. I'd try it with the drive you have. There is a low probability the drive is dead, just not properly prepared. I'll follow your procedure with it and check back in if there are any problems.

Dec 12, It seems High Sierra was released too early. Perhaps too many Mac techos have been drafted to iOS work and, as evident in other neglected areas of the Mac, it "just doesn't work". I have just nee rrying to help a friend with a Macbook Pro and High Sierra having the same problem.
You will find that you can format the drive in FAT format on a windows machine or you can go to an Apple store and get them to format the drive on a Mac running an earlier operating system Sierra or before.
