How to merge hard drive partitions?

This article introduces full solution how to merge disk partitions on Windows 10/8/7/Vista/XP (32/64 bit) and how to combine hard drives on Server 2019/2016/2012/2008/2003 (R2).

All hard drive partitions are allocated while installing Operating System, but you can reallocate disk partitions without starting from scratch. One of the methods is merging partitions together, by doing this, you can reduce the number of drives and transfer free space from one to another.

Searching by Google and there are many similar questions, for example: “is it possible to merge disk partitions without any software”, “can I merge hard drives without losing data”, “what is the best way to combine partitions”.

In this article, I’ll introduce the full solution how to merge partitions on Windows Server and PC with native tool and 3rd party software. Combine two contiguous partitions or non-adjacent drives, here we go.

How to merge partitions without software

Windows native Disk Management utility has no “Merge Volumes” feature, but you can achieve with Extend Volume functionality indirectly. This functionality is available in Windows 10, 8, 7, Vista and Server 2019, 2016, 2012 and 2008. If you are running Windows XP or Server 2003, you need to run DiskPart command prompt or 3rd-party software.

Voorzichtigheid You have to delete a volume, so remember to back up or transfer files manually before deleting.

Steps to merge partitions with Disk Management:

1. Druk op Ramen en R sleutel op uw toetsenbord, type diskmgmgmt.msc and press Binnengaan to open Disk Management.

2. For example to merge drive E: into D, right click drive E: and select Volume verwijderen.

4. Volume Wizard uitbreiden zal worden gelanceerd, klik dan op Volgende till Afwerking to start.

In a while, the Unallocated space is combined to volume D.

Partition merged

Tip You can only merge a volume into the left adjacent one in Disk Management, for example: merge drive D to C, or combine drive E to D.

If you cannot manually transfer files to other partition, or want to merge a volume into the right adjacent or other non adjacent partitions, you need to run professional disk partition software.

How to combine contiguous partitions

Stap 1: Downloaden NIUBI Partition Editor, klik met de rechtermuisknop op een van de twee partities die u samen wilt combineren en selecteer Merge Volume.

Stap 2: In het pop-up venster, selecteer beide partities en klik dan op GOED.

Tip Wanneer u twee datavolumes samenvoegt, kunt u in de vervolgkeuzelijst een van beide als bestemming selecteren. Maar wanneer het samenvoegen van C- en D-aandrijvingenkunt u alleen C als bestemming selecteren, anders zal het systeem niet opstarten mislukken. (samenvoegen systeempartitie C: naar D is uitgeschakeld)

Aandrijvingen selecteren

Stap 3: Druk op Apply knop linksboven om uit te voeren. (Deze bewerking werkt in zijn eigen virtuele modus en echte schijfpartities worden niet veranderd totdat u op de knop klikt Applyom te bevestigen).

C en D aandrijving samengevoegd

Nadat het samenvoegen van de volumes voltooid is, open je de C-schijf in Windows Files Explorer en dan zie je een vouw die de naam D tot C (datum en tijd). Alle bestanden van D worden automatisch naar deze map verplaatst.

Stap 1: Rechter muisklik aandrijving E en selecteer Volume verwijderen. (Remember to back up or transfer files)

Drive E deleted

Stap 2: Rechter muisklik aandrijving D en selecteer Resize/Move VolumeSleep de middenpositie rechtsom in het pop-up venster.

Resize volume instead of merging

If you just want to extend a volume, the best idea is resizing disk partitions instead of merging. As you see, you’ll lose a volume by combing with Disk Management or 3rd party software. You can shrink a volume to release free space, and then add the free space to the drive that you want to extend. By this method, you won’t lose partition, Operating System, programs and all files keep intact.

No matter you want to resize or merge partitions, you’d better select a safe partition tool, because there is risk of losing data when re-partitioning disk drive. Backup software is not enough especially for Windows servers, because it costs such a long time to restore and verify data if damage occur. The built-in Rollback technology of NIUBI Partition Editor kunnen automatically reverts the computer to original status in a flash, if any software error or hardware issue occur. It also provide Virtual Mode, Cancel-at-Will and Hot-Resize technologies to enhance the protection ability.
