Error 3. Failed to create a new partition on the selected unused space. [Error
You may meet the error while create new partition on a hard drive over 2TB. When you
plug-in your over 2TB hard drive to your computer, you may find it only had a 2TB
partition and the rest space is marked as unallocated space in Windows Disk
Management. When you try to create a new partition on the unallocated space, you
will get the error 0x80042468, and you may be suggested to partition the drive to
use GUID Partition Table (GPT).
That is because of the limits of MBR(Master Boot Record) disk. MBR disk is different
with the GPT disk. It only supports disk volume up to 2TB. The space beyond 2TB will
display with unallocated space. That is why you failed to create a new partition on
the selected unused space with the error 0x80042468. For this situation, you need toconvert the MBR disk to GPT disk first,
and then, you can create new partition without limitations.
*Make sure your motherboard supports EFI/UEFI mode.
Error 4. The Operation you selected will convert the selected basic disk to dynamic
Well, it is another error while create new partition. It may remind you that “the
operation you selected will convert the selected basic to dynamic...etc.”.
For this situation, you’d better check how many primary partitions on your hard drive
and whether your hard drive is MBR disk type. If there are more than 3 primary
partitions on the hard drive, and the hard drive is MBR disk, you may meet this
error while create new partition. Cause MBR disk supports up to 4 primary
partitions. If you need to create more partitions, you can only change primary partition to
logical partition to get more extended partitions. Or you can convert
the MBR disk to GPT disk, which requires your motherboard supports EFI/UEFI mode.
