processing. But is not absolutely cannot repair, the principle is very simple, as long as uses 1 sectors to replace 0 sectors to be OK, below lets us try!
This time please "Diskman" to help us, it is a more commonly used hard disk tools, in the Pure DOS run, in the "Hard drive" menu to modify the disk (generally for
failure, it will also appear above, such problems in the CMOS hard disk can recognize the hard disk, the dial is very smooth, but is not in the system, can not be normal partition and format.
6. Problems with the motherboard
Related to the motherboard is also mainly the motherboard's hard disk controller, resulting in data transmission instability, error rate
computers often do not detect the hard drive what to do
The computer often does not detect the hard drive solution one:
There are several reasons for these:
1, the hard disk itself has a problem, may be broken, with tools to de
computer does not recognize the mobile hard drive what to do
Under normal circumstances, a removable hard disk is connected to a host and the system can recognize it as a removable storage device and automatically add a letter to my computer. If the system will recognize the mobile hard
drive to make sure it is connected to the motherboard. If you find the connector loose, plug it back in. If its interface is not loose for the connector, plug it back in. If the interface is not specially designed for the connector, you should carefully inspect the board to see if there is a small "I". That's where the foot 1 should be right.
Long-term electrical expansion and contraction, will cause the
Jumper (English jumper) is a small switch that controls the current flow on the circuit board. Its role is to adjust the equipment on the different electrical signals of the relationship, and to adjust the operation of the equipment, such as the motherboard voltage, drive master-slave relationship and so on. The jumper is basically composed of two parts, partly fixed on the motherboard, hard drives and othe
With the sharing of files more and more, movies, picture games and other large-capacity data selected by the mobile hard disk as a storage carrier. Many netizens reflect, when they buy the mobile hard disk put on the computer, the system will be mobile hard disk recognized as "Unknown USB device", the mobile hard disk
What to do if your laptop can't find a removable hard drive:
System-related Setup problems
Do not assume that as long as the motherboard has a USB connector can use the mobile hard drive, but also to see if the system support. Windows2000, Windows XP and the above version of the system can directly support the mobile
Unit recently bought a new HP ProLiant DL385 server, while purchasing an HP Smart array G2 disk control array card, configured with 10 146GB of capacity of 10,000-turn SCSI hard drive, now I intend to make these 10 SCSI hard disk raid 5, so that the disk array system to maintain a large number of multimedia information task. To do this, the author quickly opened
Absrtact: We all know that the disk consists of a controller, a magnetic prime component. When we edit a file at the terminal, how does the file content get to the disk from memory? What the disk drive is primarily doing. How the hard drive interrupts are triggered. And so on, these are the fundamentals of hard disk wo
What to do if a mobile hard drive can't be identified by computer
Solutions for mobile hard drives that cannot be identified by the computer:
Method One: System-related Setup problems
1, do not think that as long as the motherboard has a USB interface can use the mobile hard
(Figure 1, 2). Just for many friends, in order to use the old hard drive to buy a new motherboard is not realistic, based on existing hardware to play their greatest effect is their pursuit, so the following is a brief introduction to the formation of SATA and pat a interface hard disk hybrid RAID System topic.
The
Method one, conventional way
Using a template may cause the virtual machine to have insufficient hard disk capacity and can be stored as data by adding a single hard disk.1. First use the DD command to create an image file size 10G under the default path:
DD bs=1m count=10240 If=/dev/zero of=/var/lib/libvirt/images/guest1_data.img
You can also use the QEMU-IMG
hard drive and you must find out why. Detection of the hard drive with a clear poison disk, found that the virus should be cleared in time.
Reboot the system with C disk, if unsuccessful, transfer the system to C disk again. If it does not start properly, it will back up the DOS
The partition table is copied to the
First, capacity
The size of the mobile hard disk capacity is the first choice for many people, usually in GB or TB units, the current market mainstream mobile hard disk capacity has 320GB, 500GB, 1TB, 2TB and so on. The size of the capacity is directly related to the user's storage needs, the choice of mobile hard disk capacity, should be based on their actual n
People who use laptops may have encountered unreadable data and failed to identify hard drive failures such as hard drives. So what are the causes of these failures? How to solve it after the appearance? How to recover data loss caused by hard disk damage? After consulting professional data recovery personnel, I consul
is very small, it is not easy to put the patent wire on the top, it is best to operate under the magnifier. In my own waste hard drive, two lines on the head are damaged. I am stuck in the wire due to too much force, resulting in a head damage, so only one hard disk is repaired, after the boot back to normal.
For hard
SATA
The full name of Sata is serial Advanced Technology Attachment,Proposed by Intel, IBM, Dell, APT, maxtor, and SeagateHard Disk InterfaceSpecification.
The SATA hard drive adopts a new design structure, which features fast data transmission and space saving. It has many advantages over the IDE Hard Drive:
disk is not formatted, it is displayed as an invalid drive. If you understand how fdisk works, you will know that fdisk only rewrites the content in the primary Boot Sector of the hard disk (0-sided 0-Sector 1-sector). Specifically, it deletes the partition table information of the hard disk, the data in any partition
Computer plug mobile hard drive does not show the solution one:
Let's take a look at Disk Management for a drive that does not have this removable hard disk. Right-click My Computer-manage-disk management. If so, you right click on the disk, choose to open, you can open it, indicating that your mobile disk is OK.
