linux erase hard drive

In Windows, disk fragmentation is a common problem. If you do not pay attention to it, the system performance may be eroded. Linux uses the second extended File System (ext2), which processes file storage in a completely different way. Linux does not have the problem found in Windows systems, which makes many people think that disk fragmentation is not a problem at all. However, this is incorrect. All file

Linux hard disk partition Basics What are hard disk partitions and what are used for partitioning? Partition is the "section" of the hard disk ". Windows partitions have their own drive letters (C:, D:, and so on), which look like an independent

After learning about the Linux system, it was still quite smooth in general. For example, all the commands that can be typed in will get corresponding results .... But today, when I learned how to mount the Linux mount command, I was really depressed for a long time. It took about two hours. I found that no solution was found for various google and baidu instances... In the end, it was an unintentional tric

written to the USB flash drive, not your first system on the disk (hard disk) above, that is, the MBR installed on your USB drive disk above, this is wrong, because the MBR is not a file, So you can't copy it from the USB stick to the disk on your first system. Because your u disk's MBR has been modified, so before the start of the U disk (U start) will not have

thought to write this, because I am in the process of tossing Linux system, there are many times to fall into the trap of the hard disk partition experience. In the last few days, once again fell into the pit, tossing two geniuses from the pit to crawl out. After a lot of inquiry data, finally understand the hard disk partition some concepts. Record it below to a

is successful. Note that for an IDE disk, the hard disk is displayed as sda after we start the boot system of the USB flash drive. When using the Windows version of syslinux, be sure to use the-m option to ensure that the master startup record MBR of ISOLINUX is copied); otherwise, the original MBR will continue to be used, this will not point to your syslinux. cfg file. The above section describes how to

measures to optimize the hard disk performance of Linux. Clear Disk This method looks simple: Clear the disk drive, delete unnecessary files, and clear all files that need to be saved but will not be used. If possible, clear unnecessary directories and reduce the number of subdirectories. These suggestions seem obvious, but you will be surprised to find that ea

This article describes how to install Linux on the hard disk and start Linux from the Grub command line. It is helpful for readers who want to install Linux on the hard disk and start Linux from the Grub command line. 1. install

, any Linux device can be viewed as a file. Therefore, you can "open" the appropriate tape drive file for write operations, and the data to be backed up is written to the file. It sounds too simple, but that's the way it is. UNIX systems treat every device as a file, as with a normal file, so that the file and device operations are as uniform as possible. From the user's point of view, the use of the device

range of the primary partition (including the extended partition) is from 1 to 4, and the logical partition is from 5;For example:Device Boot Start End Blocks Id System/Dev/hda1*1 765 6144831 7 HPFS/NTFS/Dev/hda2 766 2805 16386300 c W95 FAT32 (LBA)/Dev/hda3 2806 9729 55617030 5 Extended/Dev/hda5 2806 3825 8193118 + 83 Linux/Dev/hda6 3826 5100 10241406 83 Linux/Dev/hda7 5101 5198 787153 + 82

Linux versions are installed on hard drives in windows at, September 28. Take Linux mint 14 as an example. I. Preparations 1. Partition To ensure the security of hard disk data, we recommend that you partition at the end of the hard disk. A 10-20 GB swap is used to place the

First, install the hard drive to the physical machine. SlightlySecond, check whether the hard disk is installed correctly.Use the "fdisk-l" command to view the hard drive code.You can see that I have added a new hard

There are many ways to extend a hard disk under Linux, before it is extended. Try to see which disks exist in your space and then expand them.If it is an extension, the disk symbol is the same as the existing symbol, such as SDA device, knowledge partition is different. It could be Sda3 sda4.Suppose to be added, relative to a new hard disk, may be SDB SDCMany peo

Many people will choose to install Linux virtual machines on VMware while learning Nutch, Hadoop or familiar Linux operating system, and often do not want to allocate to the Linux virtual machine large enough hard disk space, which makes it easy to use Linux for a period of

Article Title: Use a USB flash drive to load the controller driver to install the Linux system. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems, open source, and other basic categories. Generally, we need to load some scsi

password, anyone can log into the system, making it unsafe. You also need to be very careful when updating your software. Because if the Linux kernel is updated, bootloader is likely to be corrupted. This method is not flexible compared to a system installed on a hard disk. Because the kernel that bootloader needs to be booted is the same as the kernel version of the ISO image that is installed to boot.Ful

The process for the initial process from power on/reset to running Linux user space on the X86 PC. There are several stages of entering the Linux-related code.(1) When the system is power up or reset, the CPU will assign the PC pointer to a specific address 0xffff0 and execute the instruction at that address. In a PC, the address is in the BIOS and is stored in the ROM or Flash on the motherboard.(2) The BI
