While using Disk Management to manage hard drive and partitions, many users find that they cannot create new partition on the drive because the New Simple Volume feature is greyed out. See the following picture:
Do you know what causes this issue and how can you address this problem? We will give you the details.
Usually, this issue happens to MBR hard drives larger than 2TB. When you connect a hard drive that is formatted with MBR partition style, the storage space larger the 2TB will be restricted from creating new partitions on it due to MBR disk limit.
So here comes the best solution. You can convert the MBR disk to GPT to break this limit. But there is one thing you need to pay attention to: if this drive is system disk, make sure the main board supports EFI boot mode. If this drive is data drive, ignore this requirement.
We recommend using MiniTool Partition Wizard Pro to do this job for you. (If you turn to Disk Management, you will need to delete all volumes before you can make the conversion. For system disk, obviously, this is unreasonable.) After installing it on the computer, you can refer to the following guide:
Launch MiniTool Partition Wizard to the main interface. Then select the disk you want to convert and choose “Convert MBR Disk to GPT Disk”.
If you are converting the system disk, you will receive a warning message saying that UEFI Boot Mode should be enabled. Click OK and then Apply to start the conversion.
In fact, New Simple Volume greyed out also happens on removable disks. For hard drives Disk Management marks as removable, if there is already one partition, you are unable to create partition on unallocated space. This is because Windows will not let you repartition removable storage devices, for users who want to partition SD card to increase internal storage of Android, Disk Management is disappointing.
At this time, you can also ask help from MiniTool Partition Wizard. But this time, the free edition is capable of doing this job. Download the free partition magic and launch it to the main interface. Then select the unallocated space on the removable disk, and choose Create Partition feature to get the following window. Please specify the file system as well as other properties before you hit OK.
See! You will get a second partition on the removable disk. But this is just a preview. To put this change into effect, click Apply.
By using MiniTool Partition Wizard, you can easily solve the “new simple volume greyed out USB” issue.
One more thing you may also want to know:
Sometimes, you may find that New Simple Volume is available, but you are still unable to create partition on unallocated space. Usually, this problem happens on MBR disks. For hard drives that employing MBR partition table, at most 4 primary partition or 3 primary partitions plus 1 extended partition (which can be further divided into many logical partitions) are allowed to be created on the drive. In addition, all logical partitions should be included in the extended partition. To get the best solutions, please read Fixed – New Simple Volume Failed to Create New Partition.
