    Over Provisioning on Samsung SSD (Magician)


    I left 50GB of my 500GB Samsung EVO 840 SSD at the end of the memory just for over provisioning. But it seems that they are not seen because they are allocated after my Fedora install.

    Any idea on how to work with this?

    Very slow boot time with Windows 10 Pro on SSD

    POSSIBLE SOLUTION: WINDOWS 10 UPGRADE DELETES OVER-PROVISIONING ON SSD!

    After upgrading from Windows 8.1 to Windows 10 I experienced the same slow boot issues. This wasn't anything to do with what was happening IN Windows -- the delay was happening before Windows started, and continued after I rolled back to 8.1 (my Lenovo X220
    was not fully compatible). I realized that it must be something that had changed on my SSD and I finally found out what it is:

    The Windows 10 upgrade process deleted the over-provisioning space on my SSDs!! I had set up 10% for over-provisioning with Samsung Magician for both my Samsung SSDs and after the upgrade it was gone from both drives. After re-applying 10%
    over-provisioning with Samsung Magician everything returned to normal after around 24 hours. It wasn't immediate, probably because the drive firmware needed time to get its references set up again.

    If you have a Samsung SSD you just need to reactivate over-provisioning with the Samsung Magician utility. If you have a different brand you will need to re-activate it using the method you used to set it up in the first place. Make sure you have a backup,
    because any changes to hard disk structure are potentially dangerous.

    Info: Over-provisioning space is free space that an SSD needs to use to replace bad sectors. When sectors go bad they are marked as bad and the firmware uses sectors from the over-provisioning space instead.

    BSOD UNEXPECTED_KERNEL_MODE_TRAP EXCEPTION_DOUBLE_FAULT 'probably caused by SamsungRapidDiskFltr.sys'

    Hi Ban, are you running a Samsung SSD & Samsung Magician 4.4, with RAPID mode turned on.

    If so Updating the Samsung Magician software should get rid of the BSOD's according to the Samsung forum . . .

    Or not worry about it. Manual overprovisioning is not required anyway.
