    It is unallocated space probably reserved for overprovisioning by the SSD firmware.

    Hi,

    450Mb seems a very small amount of disk space for overprovisioning to me considering what seems like a 240 Gb ssd.
    I don't know about Intel SSDs but most firmware controlled overprovisioning is invisible to the user.

    Cheers,

    There could be a way to merge the blank partition


    I believe there are ways to merge that blank partition with your C partition but need more information
    Paid versions of Macrium Reflect, Aoemi Partition Manager and I suppose some other 3rd party programs also.
    If you did not have that intervening partition merging the blank partition with your C partition would have been free and easy
    Did you upgrade from a 250(?) GB HDD to a 300(?)GB HDD?
    Is the partitioning you showed an SSD? (SSD was mentioned in a prior post)
    You mentioned imaging: was it a system image backup or was it a clone?
    Was upgrading to Win10 from a previous OS involved before or during the time that you mentioned the blank HDD partition?
    I need to note I really am not a hardware person but have dealt with a couple of situations similar to what you mentioned but followed instructions on how to deal with them.

    Hi,

    When you run disk management do you actually see this partition?
    If you don't I would leave things as they are. After all it's only 450 Mb, right ?

    Other than that you could consult the manual or Intel's site about this SSD and see how it handles overprovisioning.

    I believe the comments about overprovisioning is what’s happening. Those expert opinions are very valuable.

    As recommended you could check with Intel. Personally I would call them if you can.
    --- Do not do anything about that “blank” partition unless you know it’s the right thing do to
    --- It is only 450MB and it is part of the original setup

    In my case I have a Crucial SSD and I called them in order to set it up properly and everything went fine.
    --- But if I ended up with a “blank” partition I would have called them back and asked them about it
    --- Like you I would have questioned that “blank” partition so I could understand what’s going on and what to do about it if applicable

    It might not be necessary to do so but you could check to see if TRIM is working ok.
    Open an admin-level command window and enter the following: fsutil behavior query DisableDeleteNotify.
    Windows will respond with DisableDeleteNotify = 0 if TRIM is working.
    --- I expect it will be ok and I would then leave the SSD setup as is.

    Also, are we talking about the last actual partition (partition 3 that is 328.7 MB used out of 450 MB), or are we talking about the unallocated space after it of 449.6 MB? Partition 3 is the Windows 10 Recovery (WindowsRE) partition. The space after that is just unallocated space that could be reserved by the SSD for over provisioning, or it could just be blank space that was for some reason or glitch not included in the OS partition.

    Hi,

    partition 3 that is 328.7 GB used out of 450 GB
    Mb not Gb.

    As I understand it we are talking about the unallocated space right behind the Recovery partition.

    Compare your disk management to the MRís system image
    --- If your disk management doesnít show that blank partition then itís a MR issue
    --- Post back on what you find out

    Check out Intelís support options
    Intelģ Solid-State Drive (SSD)
    Contact Support
    I know I would want to find out about that blank partition if your disk management shows the same

    EDIT: Did you replace the computer's original HDD with the SSD?
