Windows 10: C Drive Has 3 Partitions - Is This Correct?

    Last question on the C drive. I installed Macrium Reflect to use as a backup program and when the program opened, it showed the C drive as seen in this picture. This looks funky to me. I don't know what that grey box/partition represents and the fourth box/partition on the right looks like a duplicate of the box/partition. Any thoughts?

    Thanks.

    That is Macrium ? Looks odd. But I haven`t installed it on 10 yet, no need to

    No clue why it`s showing 93 GB as blank.

    Looks as if Macrium is seeing 93.15Gb of unallocated space. You may want to check your C partition for errors. If there are none, suggest you download and install MiniTool Partition Wizard and see what it shows.

    That 93.15 GB is unallocated disk space being used for your 1TB Samsung SSD at 10% overprovisioning. Notice that actual GB for the disk is 931.51 GB, take that times 10% and what do you get?

    Thanks, I installed the mini tool and here is what it showed. It is unallocated space. No idea what that means. Also, why does it show 3 partitions: 100MB Data, C: 837GB, and the 845 MB partition (shows after the unallocated partition)? Can I delete that 845 MB partition?

    I wouldn't. It's over half occupied and probably has to do with Win 10 recovery capability.

    P.S. You can change that 10% overprovisioning if you want and reclaim whatever fraction of the 95 GB you want. Even if you reclaimed it all, whether left unallocated or not, the SSD will reach for what it needs from whatever it considers to be unoccupied system drive or unallocated drive space.

    I'm going to guess you installed Samsung Magician and that's where you ended up with the 10% OP for the SSD. Actually, I'm still not seeing anything wrong or unexpected in anything you've posted, including the Macrium screen. If you were to do a Byte-by-byte disk image with Macrium, it would store what it needs to construct even that unallocated space as it was when imaged. If you just let Macrium image the disk data present, you'll have a MUCH smaller image and it would still full disk restore to be laid out exactly as it was when the disk image was created.

    Not a problem. It was easier from the standpoint that I have same deal going as you, have a 500 GB Samsung 850 EVO, and have been using Macrium for a while now.

    EDIT - well, wish I could cram all those disks in my laptop, so not EXACTLY the same deal...
