I ran Samsung Magician to explore over provisioning of this drive. The OP Settings display shows that 93.5GB at the end of the disk are Unallocated, but marked "OP" (first clip attached).
BUT -- it also recommends a new OP partition of the same size, displayed as the gray box with a lighter outline and a slider bar.
I would like for the drive to use OP, but not twice. Is the drive already OP, as suggested the label on the lighter gray box? If not how can I recover that space and use it for OP configured by Samsung Magician? (Windows 10 Disk Manager also shows that unused 93GB at the right end of the chart -- second clip attached.)
