Avoid Sierra Disk Utility Partitioning Problems & try Partition Tool

Summary: Mac Hard drive partitioning is easily manageable through Disk Utility, but, with the launch of macOS Sierra 10.12, this otherwise helpful Mac feature has seen some unexpected issues. Stellar Partition Manager Software is ideal in performing Mac partition management functions when Disk Utility fails.

Though Apple utilities are renowned for being robust, sometimes, they fail to work on some OS versions. Take the Disk Utility for example. This helpful utility that allows users to perform Mac partition management, fix disk permissions, create disk image, and other critical tasks doesn’t work so well when it comes to latest Mac OS versions such as El Capitan and macOS Sierra. While El Capitan witnessed minor issues with this utility, many macOS Sierra users have recently posted queries on online forums about major issues where they’ve complained that Disk Utility can’t partition Mac external hard drive, is missing the disk repair feature, or cannot burn CD/DVD.

If you’ve faced any of these issues, reading this post till the very end will help you figure out an easy solution for such situations.

Partitioning issues on macOS Sierra

Some of the most common problems users faced while trying to partition their hard drives on macOS Sierra included:

  • Partition option in Disk Utility greyed out
  • Disk Utility incorrectly showing some space as occupied even after erasing hard drive
  • Error messages prompting users to repair disk permissions every time they tried to repartition it

While these problems sound quite simple, a user who encounters them repeatedly even after trying out fixes like unplug-replug, restart, and drive erase could easily get irritated. But it is important to realize that there are workarounds to every problem and if they too don’t work, you always have a reliable third-party macOS sierra partitioning tool to help you out.

A few workarounds

If you’re facing one of the above-mentioned problems, here are some workarounds for them:

“Partition” option grayed out

Try running the following command on Terminal:

diskutil erasedisk hfs+ External GPT /dev/disk2

Once the command finishes executing your drive might be named to something else (as opposed to what name you gave it earlier) and might show its own partition named simply “External,” but it will show the “Partition” option when highlighting the HDD.

Free space shown as occupied or Disk Permission errors

Try partitioning the drive on a computer running a different version of OS, for example, El Capitan. Though initial attempts may throw same errors, erasing the drive on a Mac running the different OS (El Capitan here) will most probably get rid of the false “occupied” and “disk permissions” messages. Thereafter, if you try to repartition the drive on macOS Sierra, it should work.
