How to partition and format a hard drive with FDISK command

Use fdisk to partition and format hard drives.

In this example, the fdisk is used to partition the hard disk, and after the partition is completed, the C drive is formatted. When partitioning, the main practice is to create 3 different partitions, activate the partition, view the partition information, and finally delete the created partition. When formatting, the main practice is to perform formatting operations in the DOS system and master the formatting commands in the DOS system.

1) Boot the computer to the DOS system and use the [fdisk] command to enter the fdisk main menu.

2) Create, activate, view and delete partitions on the hard disk according to the prompts.

3) Use the [format] command in the DOS system to format the hard disk.

For specific steps, please refer to the software and the content of the book to explain. Includes:

1) Create a primary partition.

2) Create an extended partition.

3) Create a logical partition.

4) Activate the primary partition.

5) View partition information.

6) Delete the partition.

7) Format the C drive.

Through this operation, users can use the fdisk tool and the [format] format command to partition the hard disk, delete the partition, and format the hard disk in the DOS system when the computer fails in the future. ;

1. Use the original system installation disk to boot the computer, take the unpartitioned hard disk as an example, select the unallocated space (SSD+HDD users need to distinguish the target hard disk according to the capacity), and click "New".

2. Give the partition size, unit MB, for example, if you want to divide the area into 30GB, write "30000" on the hand to remind: If your hard disk is large enough, the system partition can be more than 100GB.

3. Or use an SSD of about 128GB or 256GB size as the system partition, you can use the full defense spine capacity, you don't have to divide other areas, and the value does not need to change, but IT Home thinks that it is safer to divide it a little, even if it is divided into two areas The system is a single area, software, files, etc., in case the system has an irreparable problem that needs to be formatted and reinstalled, and the infiltration will not let all the files suffer.

4. When using GPT partitions, the system will ask to create MSR and EFI partitions, which are 128MB and 100MB by default, which are used to reserve space and store bootloaders, etc.

5. In the same way, divide other regions according to the above method, if you use the MBR partition mode, then you can only divide up to 4 primary partitions here, but if you use GPT partitions, the number is not limited. After partitioning, you can format it here, or you can directly click "Next", and the system will automatically format the selected system partition; Other unformatted partitions can be manually formatted after the system installation is over.

6. Win10 users right-click on the start button, select "Disk Management" to enter the program, Win7 users can right-click "Computer", and then enter "Management", find "Disk Management" in the left sidebar, the current system hard disk situation is listed here, and it can be seen that there is a black undivided area.

First: Formatting operation: If you want to use the newly purchased hard disk normally, you can right-click on the "This Computer My Computer Computer" and select "Manage" in the pop-up menu.

Then open Disk Management, if there is a newly installed hard disk, the system will automatically pop up a prompt to initialize the disk, larger than 2T hard disk, select GPT, otherwise, select MBR.

The initialization was done quickly, and a completely empty hard drive can now be seen.

Second, partition operation: partition below, right-click on the empty hard disk, select Create a simple volume, start the operation of entering the partition, the specific size, according to your own needs of the actual self-allocation, in the wizard page directly click Next.

For example, divide an NTFS partition with a size of 80G, enter the size of the volume, and then the next step; Next, it is recommended to check Perform Quick Format, otherwise it will take a long time. Proceed to the next step;

Click Done, so that there is an 80G partition ready to use.

For the remaining capacity, repeat the preceding steps to partition the capacity.

It is recommended not to divide too many plates, and about 3 pieces of 1t are fine.

Disk management.

Perform the following steps to partition a hard disk using the fdisk command:

1.Prepare the DOS boot disk.

2.Delete the logical DOS partition.

3.Delete the extended DOS partition.

4.Delete the primary DOS partition.

5.Create a DoS partition.

Note: Partitions must be deleted in the following order: Logical DOS Partition, Extended DOS Partition, Main DOS Partition. Be careful because the partition is unrecoverable after deletion and all the data in the partition will be deleted permanently.

Before doing so, refer to your computer's reinstallation guide.

Note: The fdisk tool is only available for advanced users. The command will permanently erase all the data on your hard drive. Before proceeding, make sure that you have the necessary boot** to restart your computer and install the operating system.

1. Create a partition.

Note: Generally speaking, the order of creating a hard disk partition is: Create a basic partition Create an extended partition Create an extended partition Divide the extended partition into several logical partitions.

Since we are partitioning the new hard disk, select "1" in "Figure 2" and press Enter to create the partition. Then as shown in "Figure 3".

In order to ensure the reasonable use of hard disk resources, the user should enter "n" and press enter to confirm the selection. Then the Create Primary Dos Partition interface appears, enter the capacity of the primary partition required by the user at the mark of this figure, it can be a number or a percentage, and press Enter to determine. After confirmation, the interface shown in Figure 5 will appear in the following figure, indicating that the primary partition has been defined, press the "Esc" key to return to the main menu of fdisk.

Enter 2 in Figure 3 to start creating the extended partition. For example, enter the size of the extended partition in Figure 6 and press enter to determine it. Generally speaking, we use all the remaining space on the hard disk as an extended partition.

After the extension partition is created, press the "Esc" key, and the "Figure 7" interface appears, indicating that the extension partition has been created.

Then start to create a logical partition, select "3" in the interface of "Figure 3", then create a logical partition "Figure 8", enter the size of the first logical partition, and press Enter to confirm. (Figure 8 divides the rest into a logical partition, depending on the size of your hard drive and your personal preferences!) If the general hard disk space is OK, it is recommended to divide it into about 4 areas!

After dividing the first logical partition, you can enter the size of the second partition as prompted, press enter to confirm, and then ...... the third and fourth partitionsAt the end of the partition "Figure 9", then press "Esc" to return to the main interface of the fdisk as shown in "Figure 2", now let's activate the partition. Select 2 Set Active Partiton to activate the partition, then the screen will display all the partitions on the main hard disk for the user to select (see Figure 10), only the main partition on our main disk"1"and Extended Partitions"2", of course we choose the primary partition"1"After entering, you can see that there is an "A" character under the "status" of the C drive, which means that the partition is the active partition, and then return to the main menu of fdisk.

At this point we have everything done with the partition of the new hard drive, exit the fdisk program. Keep pressing"esc"key to exit the screen to prompt the user to reboot the system, and the system must be rebooted before proceeding with formatting all the logical disks that have been created.

The fdisk hard disk partitioning tool can partition and format hard disks larger than 160g.

When we create a partition, we have already set the physical parameters of the hard disk, and specified the location of the master boot record (MBR) and boot record backup of the hard disk. For the file system and other operating systems, the information required to manage the hard disk is achieved through the subsequent advanced formatting, that is, the format command.

To use a figurative analogy, partitioning is like drawing a large box on a blank piece of paper. Formatting, on the other hand, is like putting a grid in a box. Installing software is like writing in a grid.

Partitioning and formatting are the basis for installing software, and they actually serve as a marker for computers to store data on the hard drive.

fdisk is formatted using the MBR partition table, and the limitation of the MBR partition table is its limitation. The absolute value is used in the header of the MBR partition table to mark the position of the start and end sectors of a partition, which is called the logical block number (LBA), which occupies 4 bytes and 32 bits, corresponding to the maximum addressing address 2 32-1.

If you use a 512-byte sector size, you can support up to about 2 tons, and if the operating system supports 4K sectors, you can support up to 8 tons. You can also set the starting address of the last partition to 2 32-1, so that the subsequent addressing will start from 0, and the maximum partition space (2T or 8T can be doubled as long as the operating system supports it).

Zoning principle

1.Select the appropriate partition format for the C drive.

The C disk is generally a system disk, which installs the main operating system, and usually has two options: FAT32 and NTFS. If you are installing Windows XP, it is more convenient to use FAT32. Because when the operating system of the C drive is corrupted or the virus trojan loaded on boot is removed, it is often necessary to use the boot tool disk to repair it.

However, many boot tool disks do not recognize the NTFS partition in most cases, so they cannot operate the C drive. If you are installing Windows 7, you can only choose the NTFS format.

The plate should not be too large.

C disk is the system disk, the hard disk reads and writes more, the probability of errors and disk fragmentation is also larger, scanning the disk and defragmenting is a daily work, and the time required for these two tasks is closely related to the capacity of the disk. The capacity of the C disk is too large, which often makes these two work very slow, thus affecting the work efficiency.

If the C drive is too small, just expand the capacity of the C drive, compress the disk adjacent to the C disk or delete the volume, and then get a blank unprocessed space. Then you can expand the volume to the C drive. The details are as follows:

1. In Disk Management, right-click the disk on the right side of the C drive, here is the F drive.

2. Click Delete Volume in the pop-up menu.

3. Right-click on the disk again and select Delete Partition.

4. Right-click on the C drive, select Extended Volume, and then follow the wizard step by step.

Pay attention to the important data of the disk before operation!

If the expansion is still not large enough, you can also clean up your C disk space, if you want to format the C disk, then choose the U disk reinstallation system method to achieve the purpose of formatting the C disk.
