Introduction to Interfaces
IDE interface
(Integrated-drive-electronics) is now commonly used external interface, mainly connected to the hard disk and optical drive. Using 16-bit data parallel transmission mode, small size, fast data transmission. An IDE interface can only receive two external devices.
The IDE's English is all called "Integrated
the "Start position", enter the "0", press ENTER, and then in the "End position" enter "100", press Enter the "current hard disk" place to detect the hard disk number, For example, to detect the 2nd hard drive is entered "2", enter that start detection. As shown in the figure.

be successful. This is most likely the problem with the boot sector of the hard drive.
Second, the bad Road repair method:
1, the restoration of the logical bad Road
Under normal circumstances, hard drive logical bad reason is that some genuine software will be in some sectors of the
detection operation, and then log into the Windows system interface after performing any operation is normal. Then why is the system in the detection of the hard drive, hard drive detection can not be successfully passed it? Will it be hardware damage to the hard
skipping the hard disk to start the floppy disk, so that regardless of whether the hard drive is locked, the hard drive can not be recognized with this boot floppy, so this boot disk can not be used as a normal MS-dos boot disk. Conversely, if you
boot of the hard drive's boot zone to be compromised, we can fix it using the FDISK/MBR command, or use the KV3000 disk editing feature to find out if the other 62 sectors on the 0 0 side have a backup master boot program, restore it to 0 0-side 0.
The damage to the partition table is more cumbersome. If only the partition table does not have a "80" flag or multiple "80" flags, or no "55AA" flag, we can o
parts of the hard disk, and the main boot program is part of it, which is used primarily to detect the correctness of hard disk partitions and to determine the active partition, which is responsible for handing over the boot to the DOS or other operating system of the active partition. This piece of program corruption will not boot from the hard
external box and attach the SCSI hard drive directly to the computer chassis.
Necessary tools for installation:
To install the hard drive system into the chassis, you need some tools to help you at least prepare the following two:

Hard disk failure is divided into two types of physical and soft faults, its diagnosis is based on the system after the phenomenon of electricity and the screen appears on the message to judge. When the hard disk failure, should carefully analyze the phenomenon of fault, whether it is a soft fault or physical device damage. Do not blindly remove the lid, plug the control card or easy to lower the
. If the program is damaged, it cannot be booted from the hard disk, but the hard disk can be read and written after being started from the soft drive or optical drive. The solution to this fault is relatively simple. It is most convenient to use the FDISK of the higher DOS version. When the FDISK with parameters/mbr i

1. When installing CentOS with a USB flash drive, partition partitions should note: The system (contains Win7) can only be 4 primary partitions, so you can only delete a primary partition or in the extended partition in the free partition to establish the directory.2, CentOS at the end of the installation step, the boot loader option only "installed on the USB stick" One, note: not easily installed on the MBR, will overwrite the Win7 system boot loade

First of all, we first confirm that the hard drive is bad logic or physical bad way, the method is very simple. In the computer just started, press the "F8" button, select "Command Prompt only" into the DOS mode (the operating system must be win95/98, if for win2000/xp please use the DOS boot disk), the implementation of "ScanDisk x:" (X for the letter), The ScanDisk program will check the
There are two fault prompts for Hard Disk Self-check by microcomputer: "HDD Not Detected (Hard Disk Not Detected)" and "HDD Control Error (Hard Disk Control Error) ". The following describes how to fix the vulnerability.
First, wash your hands with water to clean the oil and sweat on your hands. At the same time, remo
As the most important storage device of a microcomputer, hard disks play an important role in the microcomputer system. If the hard disk cannot be started, it will cause you to be in a hurry. Here we will introduce you to several "weapons" to specifically deal with the "stubborn" problem that hard disk cannot be started. You must be careful when using them. Other
