Removing overprovisioning from ssds in windows 10

[Teo222]

Says I cannot remove overprovisioning because it is not the last accessible partition. 850 EVO ssd. Samsung magician and windows utils don't work in windows 10. How can I remove overprovisioning?

EDIT: Found the solution by deleting recovery partitions https://www.youtube.com/watch?v=Ygtq_2ejcPI
recovery was the last accessible so you couldn't remove overprovisioning from the primary drive.

Recovery partitions are not over-provisioning, but good to hear you fixed it.

Over-provisioning might be able to be reduced using software tools, but you won't be able to eliminate it without seriously modifying the drive's firmware...

I just went through this with Window 10 Preview Edition. Over provisioning is built into windows ten. So setting up OP in Samsung ware is impossible cause it already enabled. I didn't know this at 1st and went in and looked at my "Disk management" and it shows my C: drive consisting of : main partition /Healthy recovery partition /50 GB of unallocated space(ssd is 512 so its inline with 10% ish for over provisioning)... SO after further research discovering win 10 manages OP for you I thought win 10 just isn't doin as good a job . SO I took the following steps to Discover I just don't need the Samsung Software to manage my OP .
I started with successfully removing the recovery partition reallocate the space to setup the Samsung ware to handle the OP. So I went into disk management and deleted the Recovery and reallocated the space to allow Samsung to manage the OP it worked ! speed and space were there and all was well. However upon an update or restart a week later I had a restart that took several minutes. The system restored the recovery partition I'm assuming cause I have "system protection enabled" so it creates this drive for recovery. I since cleaned up my drive uninstall Samsung software, went to window 10 Defrag as it now recognizes SSD's and forces the trim command. ( it doesn't Defrag ! ) and ran a "crystal disk" Benchmark and my speed it back ... I suppose you could delete recovery all together but 1st turn off system protection or it will just put it back.

EDIT (Week later new build14936.rs ) I've completely removed the "recovery drive" and made the full drive space accessible Turned overprovisioning off and win 10 doesn't not "create" a OP space. at least thus far.
