Note: A hard disk can only be divided into four primary partitions at most, or three primary partitions plus one extended partition. This is because the most important information MBR (Master) of the hard disk is stored in 512 bytes in the 0 head, 0 column, 0 side, 0 track, and 0 sector of the hard disk Boot Record，Master boot record) and partition information. Since the record space is only that large, only the information of these four partitions can be recorded. 1、 Disk split description: 1. A primary partition can occupy all or part of the space of a disk. A hard disk can have up to four primary partitions, and a primary partition can be formatted into a single logical drive (rather than multiple logical drives) 2. Any primary partition on a hard disk of the computer can be designated as the active partition. It is important to activate the partition.Because when the computer starts, it tries to load the operating system from the active primary partition on the first hard disk of the computer. 3. A hard disk can only have one extended partition.The extended partition cannot be identified as the active partition and cannot be used as the system partition of a computer. 4. An extended partition can be divided into one or more logical drives.Each partition is assigned a different drive letter.The logical drive can be formatted as FAT or NTFS.You can format a logical drive in FAT format and another logical drive in the same extended partition in NTFS format. 2、 How to set the primary partition: Preparation: one non partitioned hard disk, one SATA cable or one USB hard disk. 1. Download DiskGen partition software and install it on the computer; 2. In the power off state, attach the empty hard disk to the motherboard through the SATA cable; Or when starting up, insert the USB hard disk box directly and put the empty hard disk in the hard disk box. 3. Open DiskGen and click "New Partition"; 2. On the page that appears, select Primary Partition, Type, and Size. 3. Use this method to partition the remaining space. Note: This method can only divide 4 primary partitions, and the first partition is the active partition by default.
You mean the 879G one?Right click to see whether you can choose to change the drive letter and path. If you can, assign a drive letter to it and format it in NTFS format.However, this partition is too large. If there is no data in it, you can delete it and use the diskpart command to create an extended partition, and then create several logical partitions.
