1. Tracks, cylinders and sectors The structure of the hard disk disc group is shown in Figure 1. The track (Track) is a concentric 阏 trajectory formed when the head of the hard disk 屮 reads and writes data on the disc surface. The track of the hard

　　0-Track Repair The 0 track is in a very important position on the hard disk, and the primary boot record area (MBR) of the hard disk is in this location. The MBR is located on the hard disk's 0-track 0-cylinder 1-sector, which holds the

I. How does the system identify hard disks during initialization?1. The system identifies the hard disk based on the MBR information at the beginning, including some execution files to load to the system. These execution files are the boot loader program in 446bytes before MBR, the following 16x4 space is the location where the partition table information is stor

After hard disk data is damaged for various reasons, can we blame ourselves?The full solution of this example is to hope that readers can quickly find the corresponding solution when the unfortunate situation occurs, so as not to waste their hard work.Of course, our greatest expectation is that you will never use the following methods! Because a complete post-eve

After the software is installed, it is likely that it cannot be uninstalled. The solution is to enter fdisk/MBR in pure DOS mode (not in Windows mode. I started the command with old Mao Tao and did not use the command. It is estimated that the boot partition is not a hard disk, later I thought of the Windows Recovery control platform with the repair MBR command (fixmbr), then I used the Windows installation

There are many ways to expand a hard disk in linux. Before expansion, try to see which disks exist in your space before expansion. If it is an extension, the disk symbol is the same as the existing symbol. For example, if it is an sda device, the Knowledge partition may be sda3 sda4. If it is added, it may be sdb sdc relative to a new

Memory virtual hard diskImprove ArcGIS Server A Method for concurrent performance WY 1. Question raised 1.1 Overview There are many ways to improve the concurrency performance of ArcGIS Server. This article discusses how to use memory to simulate hard disks to improve data reading efficiency when the user's hardware is powerful enough (mainly the memory is large enough, to improve the concurrency performan

first, how to identify the hard disk when the system is initialized1, the system initially according to the information of the MBR to identify the hard disk, including some executable files to load the system, these execution files are in the MBR in front of the 446bytes boot loader program, and the back of the 16x4 sp

Common Fault One: the system does not recognize the hard drive The system can not boot from the hard drive, boot from a disk can not enter the C disk, the use of the CMOS automatic monitoring function can not find the hard drive. Most of this fault occurs on the connection

Hard Disk partitions The most common tool for partitioning a hard disk is fdisk. It exists in the Windows 98 Startup disk or in the Windows\Command directory of the system disk. The following is a detailed description of the ste

As one of the core components in the computer, hard disk plays an irreplaceable role in the work. Especially now the integrity of large data age, hard disk storage of various data information, hard disk life is particularly import

Whether it is installing Windows or Linux operating system, hard disk partition is the most difficult part of the whole system installation process, some of the online Ubuntu Linux installation tutorials are generally automatic partitioning, for beginners to bring great inconvenience, I will talk about the most reasonable way to install the hard

1. Hard disk power supply: The power of the hard drive from the host's switching power supply, the voltage of four terminals are: Red is 5V, black for ground, yellow is positive 12V, through the linear power conversion circuit, to transform the normal work of the hard disk v

① first checks to see if Cmossetup has lost the hard drive configuration information. Measurement of the motherboard on the Comsram circuit for battery failure, or components (such as diodes, transistors, resistors, capacitors, etc.) damage can cause and the CMOS hard disk configuration parameters error. ② through the electric self-test, if the screen display er

Here's how to deploy a Windows 8 installation to a removable hard disk under Windows 7. When we install Windows 8 to a removable hard drive, we can start and use Win8 on the mobile hard drive. This way, you can carry a portable hard drive, plug into any other comp
