How to build an OP partition on an SSD drive
On a newly installed Crucial 500GB SSD (MX300), setting up an OP-Partition failed with a message, 'Not enough room' to install.
While the SSD is installed as a slave / secondary drive, and before you clone the disk, format the entire drive as a Simple volume, assigning any drive letter.
Then, running Cruicial's Storage Executive, create the Over Provisioning partition on the blank disk.
Later, when cloning (using the free version of Acronis HD, or any other cloning software), manually set cloning options, where you will manually adjust the partition sizes. Example steps on how to do this can be found in the keyliner article: How to install a Crucial MX300 SSD Drive.

Install the New Drive
Format and Enable Over Provisioning and
Clone the disk
