Hard drive Bad track repair knowledge

Classification of Bad DAO

The hard drive has a bad way in addition to the quality of the hard disk itself and the reasons for aging, but also to a large extent due to improper use of the cause. Hard drive bad road according to its nature can be divided into logical bad road and physical bad road two kinds, in short, the logical bad way is caused by some software or improper use, this kind of bad way can use software repair, and the physical bad way is the hard disk itself magnetic media problems, such as the disc has physical damage, This type of failure usually uses software that cannot be repaired.

There's a bad way. If you have any of these symptoms on your hard drive, you should be aware that the hard drive has broken down:

(1) Read a file or run a program, the hard disk repeatedly read the disk and error, prompting file damage information, or to be successful after a long time, sometimes even a blue screen;

(2) The hard disk sound suddenly from the original normal friction sound into a strange sound;

(3) In the case of excluding virus infection, the system can not start normally, appearing "sector not found" or "general error in Reading drive C" and other prompts;

(4) Format hard disk, to a certain progress stopped before, the last error, can not be completed;

(5) Every time the system boot will automatically run ScanDisk scan disk error;

(6) to the hard drive to perform fdisk, to a certain progress will be repeated into retreat;

(7) boot can not be through the hard disk boot system, with a floppy disk may be turned to the hard drive letter, but unable to enter, with the SYS command conduction system can not be successful. This is most likely the problem with the boot sector of the hard drive.

Repair physical bad road-low grid hard drive method more

Low-level format of the hard disk in the way there are two kinds, one is through the motherboard BIOS from the low grid tool, one is the use of software to the low lattice. The method of using the low grid tool with the motherboard BIOS will be limited by the motherboard, some motherboards are not equipped with such a program in the BIOS, and most of the new model of the motherboard is not the function of the low grid, so the recommended or software to the way to the low-level format of the hard disk.

Maxtor produced a low grid tool Low.exe, the software can be maxtor hard disk, in fact, this program can be applied to various brands of various models of IDE hard disk. The operation of the software is quite simple.

After startup, press "Y" to enter the software, just select the hard drive that you need to lower the grid, and then select the hard drive on which to start the low grid selection. Computer knowledge

The general low lattice process is longer, so it takes patience to wait. Also, it is important to remind the reader that if you have other hard drives installed on your machine, it is best to remove the hard drive when running the low Low-pass program to avoid data loss.

Warm tip: It is recommended to complete the bad block after the new partition for a scan, still recommend the use of ScanDisk, to ensure that the bad road has been completely shielded to the hidden partition. Of course, if you feel pity, you can also set up a new partition before the bad way, of course, the premise is not to divide the bad way into the new partition again, but do not recommend this, lest partition too much and too fragmented, will greatly affect disk performance.
