Is it necessary to leave some space for hard disk partitions?

No. That would be a waste of space, and it would be a partition error.

When partitioning, if it is in MBR mode, do not check it (Win7 system).

If it is UEFE+GPT mode, you need to check ESP (Win10 system).

Disk partitioning is to use a partitioner (Xiangshen partition editor) to divide several logical regrets on the disk, which is essentially a formatting of the hard disk, and then the hard disk can be used to save various information. For some operating systems, the hard drive must be partitioned before it can be used, otherwise it cannot be recognized.

Reserved free sectors: For the GUID partition table, you can reserve a specified number of free sectors between partitions to facilitate the conversion to MBR mode in the future.

What should I do if I feel that my computer's hard disk is not evenly distributed, or that one of my hard drives is not enough? We can reallocate hard disk space to the computer, the following is how to reallocate hard disk space that I have collected and organized, I hope it will be helpful to you

Methods for reallocating hard disk space

Method steps.

Right-click [My Computer], select the [Manage] command, and open "Computer Management".

In the Computer Management window that opens, select the Storage and Disk Management items. In the right pane, you can see the partition status of the current hard disk.

That's when we can allocate space freely!

Take the distribution of G disk as an example:

Right-click [G disk] - [Compress Volume] and enter the size of the space to be allocated in the pop-up box. Then click Compress

Then right-click on the free space you just allocated and select New Simple Volume.

Well, the distribution is complete.

Symptom 1: After the device is turned on, the screen displays: device error

Or display: non-system disk or disk error, replace strike any key when ready

Explain that the hard disk cannot be booted, after booting with a floppy disk, type c:> after a:, and the screen displays:

invalid drive specification", the system ** does not recognize the hard disk. Fault analysis and handling: The cause of this fault is usually caused by the loss of disk setting parameters in CMOS or the wrong disk type setting.

Symptom 2: After the computer is turned on, the "wait" message stays for a long time, and finally the "HDD controller failure" appears. Fault analysis and treatment

The cause of this fault is usually poor contact or incorrect wiring of the hard disk cable interface.

Fault symptom 3:

After booting up, the screen displays: "invalid partition table", the hard disk cannot be booted, if it is booted from a floppy disk, it will be recognized as C disk. Fault analysis and treatment

The cause of this failure is usually an error in the partition table in the master boot record of the hard disk, and the above prompt will occur when multiple bootstrap partitions are specified (only one bootstrap partition can be specified) or when a virus occupies the partition table.

Symptom 4: After the self-test is completed after booting, it crashes or the screen displays: "No ROM Basic, System Halted" when booting from the hard disk.

Fault analysis and treatment

This is usually caused by a corrupted bootloader or virus, or the absence of a bootstrap flag in the partition table, or an override of the end flag 55aah. Boot from the floppy disk and execute the command "fdisk mbr". The fdisk contains the master bootloader** and the end flag 55aah, and the above command can be used to make the correct master bootloader and end flag in the fdisk overwrite the master bootloader on the hard disk, which is a quick and easy way to fix the damage to the master bootloader and the end flag 55aah.

If there is no bootstrap flag in the partition table, you can use NDD to quickly recover from the fault.

As for this, if it's adjacent, it can be expanded, but if it's not connected, it doesn't seem to be. Some third-party software can be merged, but I think this will damage the hard drive. For example, if your D drive is next to the free part, that is, the part of the storage area that has not been allocated or created can be extended to the D drive.

The details are as follows: Solving common problems with computers.

1. The hard disk controller cannot be automatically recognized.

Using non-genuine individual operating system discs, while installing the system, is prone to this error. The reason is that the hard disk controller driver that is automatically loaded by the non-genuine disc does not meet the needs of the computer itself. In this case, it is recommended to install the operating system on a genuine CD.

2. Manually update the wrong driver.

The Windows operating system is used normally, but manually updating the driver to update the driver of the hard disk controller is wrong, resulting in this failure. The solution is to enter the advanced menu of the Windows system and select the last normal configuration, and then you can enter the system normally.

3. Caused by changes in BIOS settings.

The Windows operating system is normal, but due to some reasons, the user modifies the BIOS settings, resulting in 0x0000007b impermeability.
