Hi guys so I have 2 Seagate hard drives that works perfectly well, but when I upgraded my mac to macos sierra, it just suddenly wont read it. My mac is MacBook 2015
Seagate external hard drive cant be read in macos sierra
With the disk(s) connected, please share outputs from the following commands:
diskutil list
diskutil cs list
I am having the same trouble... they are now showing up as unreadable to the mac... I checked the drive on a pc and was able to get in there and look at the files and media.

Is /dev/disk3 (internal, physical) one of the two Seagate drives?
Same here. My Seagate 1TB is not mounting on MacOS Sierra. Tried it on mac running el Capitan and it works just fine. What should i do?
Hi ,
I had the same issue with Seagate 1TB HD, and I've just install this driver http://www.seagate.com/br/pt/support/downloads/item/ntfs-driver-for-mac-os-master-dl/ and it is now working perfectly.
iv had the same problem with 2 of my seagate drives they worked fine before i updated my OSX so whats the fault with sierra when it worked on the capitain perfectly fine ??

The same problem, but I installed the program and now works fine. I feel bad that Apple do not consider this problem.
I am having the same problem with my Mac Book Pro-2015, I upgraded to Sierra and now I cant use my external Hard Drives, I have 2 of them , 1 is a Toshiba 2TB, and the other one is Touro 1 TB HDD,it wont read them is there a software program i can use to fix this problem?
I am getting the same problem now on mac OS Sierra,
I am having seagate 1TB external power hard drive with 2 partitions with following file system
1. OS X Journeled
2 . FAT32
Now suddenly only OSX Journled partiion is getting mounted and I could not see FAT3.
If I run the command "diskutil list" i can see both the volumes but in finder and diskutility only 1st partition is seen,
IS this the os problem? It occured just now.
thanks man sure seems to be working after i did this
I did this but all I get is a message telling me that the NTFS_for_mac/dmg is damaged & I need to trash it. So no joy here
Thanks!!
Finally resolved! A week and a 1/2 later plus 2 so called computer repair shops.
this helped
Perfect. Thanks!
I did this. My drive shows up in the System Report, but not in the Finder, and Pargon NTSF for Mac, now in System Preferences, lists no drives.

Thank you very much .... this resolved the issue.
You could of damaged your drive. That happened to me on an upgrade from Mac OS X Mavericks (10.9.5) to macOS Sierra (10.12).
This driver only works with older versions of MacOS, not High Sierra.
