Windows 10 cannot extend volume

This post explains why can"t extfinish volume in Windows 10/8/7 Disk Management and what to execute once cannot extend C drive for Windows 10 laptop/desktop computer.

You watching: Windows 10 cannot extend volume


Nowadays, many kind of Windows 10 computer systems use SSD for Operating System and programs. It is advantageous to improve computer system performance. However, comparing with conventional mechanical disk, SSD is a lot smaller sized bereason it is still expensive. So the partitions are even more likely running out of area, especially to the system C drive.

From Windows 7, brand-new Extfinish Volume attribute was added in Disk Management to assist extfinish partition without losing data. However, this function just works under certain problem. Windows 8/10 inherited the exact same feature without development, so many kind of people encounter issue while extfinishing partition. The typical example is that Disk Management cannot extend C drive after shrinking D. In this post, I"ll explain all probable factors why cannot extend volume in Windows 10/8/7 Disk Management, and also how to resolve this problem rapid and also easily.

Why can"t extfinish C drive in Windows 10/8/7 Disk Management

Reasons 1: no Unallocated area next to C drive

In a Windows computer, there are 3 forms of space on a tough disk:

Used space - already occupied by miscellaneous forms of papers.Free space - empty space in a partition that deserve to be used for brand-new records.Unallocated space - blank space on a disk but is not belengthy to any type of partition.

In Windows 10/8/7 Disk Management, Unallocated area can be offered to create brand-new volume or linked to various other partition. To acquire Unallocated room, you might either delete or shrink a partition. Since the size of a physical disk is addressed, prior to extending a partition, you must delete or shrink one more partition to obtain Unalsituated space. Without such type of area, of course you cannot extend partition in Windows 10/8/7 Disk Management.

Obviously, it is better to gain Unalsituated space by shrinking a partition, bereason you won"t lose records in it. The trouble is, you can not extfinish C drive in Windows 10/8/7 even after shrinking D or any various other partitions, because Disk Management has actually many type of shortages.

This is the most common reason why can not extend C drive in Windows 10/8/7 Disk Management. As you check out in the screenswarm, I cannot extfinish C: drive and E: drive after shrinking D. Because, C drive is nonadjacent to the Unallocated area, E drive is on the ideal.


Reasons 2: the contiguous partition is Logical

Because I can not extfinish C drive in Windows 10/8/7 Disk Management after shrinking D, I tried to delete the surrounding D drive in my test computer. As you view, Disk Management is still unable to extend C drive.

In Windows computer system, there are 2 types of disk - GPT and also MBR. On GPT disk, all partitions are produced as Primary. But on MBR disk, tright here could be Main and Logical partition. In enhancement, you deserve to only produce maximum 4 Main partitions, or 3 Primary partitions plus an Extended partition on MBR disk.

Primary partition works as an independent unit, yet Logical partition is part of the Extended partition. After deleting a Key partition, its disk area will be changed to Unallocated, however after deleting a Logical partition, it will be adjusted to Free space.

While extfinishing partition in Disk Management, Unallocated space can"t be extended to any kind of Logical partition. Free area can"t be extended to any Main partition. In a word, if you desire to extend C drive by deleting D in Disk Management, D need to be Primary partition, because C drive is always Main. (Note: D drive in this article suggests the contiguous partition behind C drive.)

What to execute as soon as cannot extfinish C drive partition

Follow corresponding solution according to your own disk partition configuration.

Systems 1: move partition and also Unalsituated space

As I explained above, Disk Management can not extend C drive partition once Unallocated room is nonsurrounding. As such, you must move Unalsituated room from right side of D to the left.

Steps as soon as can"t extfinish C drive in Windows 10/8/7 after shrinking D:

Tip 1: Downpack NIUBI Partition Editor, appropriate click D: drive and also pick "Resize/Move Volume", drag the middle towards right in the pop-up window.

Solution 2: shrink and extend partition through NIUBI

If the contiguous partition D is a Logical drive, as I explained above, Disk Management is unable to extend C drive by either shrinking or deleting D. It is exceptionally simple to deal with this problem with NIUBI Partition Editor.

Right click D and also pick "Resize/Move Volume", drag left border in the direction of best in the pop-up home window, then Unalsituated space is made on the left.

Other reasons why cannot extend volume in Windows 10/8/7

When you extend a data partition by means of Windows Disk Management, you may enrespond to additional problem.

FAT32 partition can not be extfinished even if there"s contiguous Unalsituated area on the best. Disk Management can only extfinish NTFS partition.Disk Management cannot extend volume past 2TB on a MBR disk.

Besides helping deal with the issue that can"t extfinish volume in Windows 10/8/7, NIUBI Partition Editor helps you carry out many other disk partition monitoring operations such as copy, transform, merge, defrag, wipe, hide partition, scan bad sectors, and so on.
