Essential Tips for You to Successfully Merge Hard Drives

Now before we get into the details of each step, there are a few tips that you need to know.

• Increasing C drive across two disks is possible but not in the way of converting two disks into dynamic .
• Conversion of both HDDs/SSDs into dynamic disks is mandatory for combining them. (See how to convert basic to dynamic)
• Back up your new volume regularly as a corruption of one of the drives will lead to failure of the whole volume.

Method #1- Combine Multiple Hard Drives into One with EaseUS Partition Master

EaseUS Partition Master is a comprehensive partition manager that enables users to create partitions as well as resize, merge, clone, and format them. It basically helps you to manage Windows partitions without losing any data. It can even create, format, and delete USBs, SSD, HDD, and SD cards. 

You can use this partition magic software to merge your multiple hard drives into a single volume. Simply follow the steps given below to achieve your target.

Step 1. Convert Basic into Dynamic

• Click "Disk Converter" and select "Basic => Dynamic". Click "Next" to continue.

• Select the disk that you want to convert to Dynamic and click "Convert" to start the disk conversion from the Basic to Dynamic.

• Go to "Disk Converter" and choose "Basic => Dynamic" again. Select the other disk (with at least 1M free space at the end of the disk) and convert it to a dynamic disk in the same way.

• When both disks have been converted into dynamic disks, as shown below, you can follow Step 2 to merge free space from one disk to another now.

Step 2. Merge Two Disks into One Disk

Note: The other dynamic must be unallocated space. If it's not, use EaseUS Partition Master to delete all the partitions on it. What's more, you cannot merge a system partition even if you have converted it to dynamic.

• Select the full disk, right-click on it and choose "Resize/Move".

• Use your mouse to drag the partition panel rightward or leftward to extend partition size. The "Fill in all unallocated" button can help you quickly utilize all unallocated space.

Sometimes, the unallocated space is on the left of the partition you want to extend. If you want to move unallocated space, just drag the left partition handle leftwards to the size you want.

• Click "OK" and "Execute 1 Task(s)".

Apart from merging multiple volumes as one on a disk, EaseUS partition manager software also provides you with flexible resolutions to deal with the following tasks, for example:

Method #2- How to Combine Two Hard Drives/SSD Drives with Disk Management

You can create two different types of volumes with Disk Management: Spanned and Stripped. Spanned Volume is used when you want to combine files having different sizes while Stripped Volume can only be used to combine files having the same size. Another difference between the two is that spanned volume utilizes drives sequentially which means it will not use the second drive until you fill up the first one while stripped volume uses both drives simultaneously which increases read and write performances. Choose the volume that suits your needs best. i.e., if you want to combine two drives with different volumes, create a new spanned volume. But if you want faster performance, opt for a new striped volume.

Mentioned below are the steps to combine two hard drives or two SSD drives using Disk Management.

• Go to Start.
• Type diskmgmt.msc into the search box to launch the Disk Management Tool.
• Before proceeding, make sure that both drives are unformatted and do not have any partitions. Also, make sure they are dynamic by right clicking them and selecting convert to a dynamic disk. 
• Right click on the drive that you want to combine. Now select New Spanned Volume or New Stripped Volume from the drop-down menu.
• The New Spanned/Stripped Volume wizard will pop up. Click next once it appears.
• Add the second drive (you can add multiple). 
• Select a letter for your new drive, format the new volume and complete the wizard.
• The Windows Disk Management Tool will now show this new volume that you created listed at the top. The two drives that you combined will be highlighted in purple.
