Question

Hard Drive Partition

Apr 6, 2016 7:58PM PDT

I have 3 primary partitions on my hard drive. The hard drive is MBR. 20 GB are unallocated space. When I try to make a new fourth volume it said, "You cannot create a new volume in this unallocated space because the disk already contains the maximum number of partitions."

This is a limit for Windows.

You can use it in other OSes. Such as Linux. There's a bootable CD/USB called GPARTED that you can prove this in.

MBR disk have limitation
Apr 8, 2016 2:10AM PDT

MBR disk only supports 4 primary partitions at most, if you want to have more partition on it, you should make one partition extended partition first and then add partition known as logical partition. Actually, I used to use AOMEI Partition Assistant to create partition and the fourth partition of MBR disk became an logical partition by default.

ps. when create more than 4 partitions, from the forth, next partitions will become logical by default and there will be 3 primary partitions and many other logical partitions on the disk.

it seems the hard disk was configured with MBR which supports 4 primary partitions or 3 primary partitions and 1 extended partition at most. If you want to fix the maximum number problem to create more partitions,you can convert the last primary partition to logical partition, and then create a new primary partition in the unallocated space. You can try to use partition manager which is quite easy.
