FAQs About Disk Already Contains Maximum Number of Partitions

Do you know how to fix the "disk already contains the maximum number of partitions" error? Here, I list some other questions for you. Continue to read if you are interested.

1. What is the maximum number of primary partitions that can be created on a hard disk?

In general, if your disc is an MBR, you can create up to 4 primary partitions. Or you can create three primary partitions and one extended partition to accommodate logical drives. If your disk is a GPT, you can have up to 128 partitions without distinguishing between "primary" and "logical" partitions. By default, all partitions on a GPT disk are primary partitions.

2. What is the maximum number of partitions a GPT disk can have?

128 partitions. The space that is reserved for partition entries in the GPT disk limits the number of partitions.

3. Can you have more than four partitions?

Yes, GPT disk allows you to create 128 partitions, while MBR allows you to create three primary and one extended partition. And you can create as many logical partitions as you want if you have enough free space.
