A:

You need to update the Paragon NTFS driver. You can find the updated version on Seagate's support site at:

Hi there, Arindamdeb3000!

Thanks for reaching out to the Apple Support Communities! It sounds like you are having issues with your external HD since your update to Sierra. I know how important it is to be sure it is recognized by your computer at all times. First, try using another cable and a different USB port to see if there is any difference.

What you might want to try next are some specific restarts. Check out this article to Try safe mode if your Mac doesn’t finish starting up. While this article speaks about the computer not starting up properly, it can also run repairs and stop startup items that can cause issues.

Next, check out this article with steps how to Reset the System Management Controller (SMC) on your Mac.

Cheers!
