Why does the computer only have one C drive?

The computer only has one C drive because the computer did not divide the disk when installing the system, so there is only one drive; hard disk partitioning is essentially a formatting of the hard disk, and then the hard disk can be used to save various information. It is recommended to keep the partitioning method of two disks.

Why does the computer only have one C drive?

Because there is no partition when installing the system on the computer, only one disk.

According to common sense, most people divide it into four disks, but dividing it into two is the best for the hard disk. Too many partitions will affect the life of the hard disk, so it is recommended to keep the partitions of two disks. Way.

Hard disk partitioning is essentially a formatting of the hard disk, and then the hard disk can be used to save various information. When creating a partition, the physical parameters of the hard disk have been set, and the storage location of the hard disk's master boot record (Master Boot Record, generally referred to as MBR) and the boot record backup has been specified.

The information required by the file system and other operating systems to manage the hard disk is achieved through the subsequent high-level formatting, that is, the Format command. In fact, you can create just one partition to use all or part of the hard disk space. However, no matter how many partitions are divided, or whether a SCSI hard disk or an IDE hard disk is used, the primary partition of the hard disk must be set as the active partition before the system can be started through the hard disk.

Extended information

1. Select menu:

1.Easy Disk installation

Hard disk automatic partition option, this is to provide DM with hard disk automatic partition option . After selection, DM will automatically perform partitioning operations based on the hard disk capacity. This function is more suitable for beginner computer users.

Tips: With automatic partitioning, the system will not prompt the user to partition the hard disk, and can only proceed in the default way. It is not recommended to select this option.

2.Advanced Options

Advanced options, this option is a manual partitioning option provided by DM. After selection, a secondary submenu will appear:

Manual Partition Secondary Submenu

There are three options in the secondary submenu. The functions of these three options are: Advanced Disk Installation ( Hard disk partition advanced options); Maintenance Options (maintenance); Upgrade Disk Manager (modify and upgrade the hard disk driver ONTRACKD.SYS, and identify large-capacity hard disks).

2. Actual partitioning:

1. Select the Advanced Disk Installation option and DM will automatically search the hard disk. After the search is completed, the system will ask you which partition format to use.

2. Select partitions: Since you need to set the size of each partition yourself, the first two automatic partition options are not considered. Directly select Option (C) Define your own to manually partition the hard disk.

3. Set the size of each partition: first enter the size of the primary partition, and then enter the size of each logical partition in turn (please note that unlike Fdisk, there is no option to create an extended partition). After completing the partitioning, select the "Save and Continue" option, and then click "OK" twice in succession to save the setting results. If you are not satisfied with the capacity of any partition, you can press the Del key to delete the partition and then re-establish the partition.

4. Complete the formatting of the partition

After saving the partition information, press the "Alt C" key combination to continue the operation. The system will prompt whether to quickly format each partition of the hard disk. Select " Y" to quickly format each partition.

After all operations are completed, the system will prompt to restart the computer (the settings will only take effect after restarting).
