Unsupported System Drive: Last Partition Unable to Resize Error





What is happening?

You are enabling Intel® Optane™ memory for system acceleration. The end of the targeted drive to be accelerated must contain at least 5MB of continuous unallocated space. The drive requires space to store configuration information to successfully pair the drive to be accelerated with the Intel® Optane™ Memory Series module.

You see an error stating the last partition cannot be resized.

Why is it happening?

You may encounter this issue due to:

  • Not enough free space on the drive to be accelerated
  • A locked partition at the end of the drive, commonly a recovery partition. After an OS upgrade, the system may generate a locked partition at the end of the drive.

How can I resolve it?

If you see this error while enabling system acceleration, do the following:

  1. Download an application that is able to resize partitions:
