What is happening?

You are enabling Intel® Optane™ memory for system acceleration. The end of the targeted SATA OS drive must contain at least 5MB of continuous unallocated space. The SATA drive requires space to store configuration information to successfully pair the SATA drive 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 SATA drive
  • 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:

  2. Resize (shrink) the partition to create at least 5MB of unallocated space at the end of the targeted SATA boot drive
