Hard drive is relatively weak, it will produce bad sectors if used improperly, this is a prelude to scrapping the hard disk, you should back up important data in advance. Hard disk damage points “logical bad sectors” and “physical bad sectors” two. The former general available software repair; the latter track that had a physical hard disk damage is not repaired.
Hard disk has bad sectors, generally as follows: when open and run the file, the hard drive speed significantly slower; or clearly heared hard disk “Titicaca” sounds, and sometimes the system will prompt can not read and write files. Boot disk scan, can not be passed, or scan certain locations marked in red “B”. Severe cases, the hard disk will not boot, boot with the floppy or CD drive letter is visible, but can not operate it or simply do not see the letter.
Windows Scandisk program is the most commonly used tools to address the logical hard disk bad sectors. This is done in “My Computer” select the drive letter to be dealt with, right click select “Properties”, in the event of the “Tools” button, select “troubleshooting” in the “Start Check” and then the “Scan Type “select” full inspection “and” Auto repair error “ticked, click” Start “button. Of course, under the command prompt, use the chkdsk command is the same effect. It can detect the hard disk have bad sectors, bad clusters that appear to do automatic amendment to the bad cluster with black red in “B” (bad) mark.
If you can not entered the system, you can start the computer with a floppy disk or CD-ROM in the appropriate drive letter, “A:” run “scandisk + the hard drive letter will be scan ” to repair the hard disk scan.
Some other disk repair software such as Norton Disk doctor and Pctools is also frequently used tools, usage is simple.
If the hard disk have physical bad clusters or bad sectors that can not be repaired, you can hide some of their software in order to avoid bad sectors disk diffusion. Such as the use of Fbdisk, will be re-partition the hard disk with bad sectors and bad sectors set to hide the partition, the partition can be a good track set will be separated to prevent bad sectors spread bad sectors. If bad sectors on the hard disk 0 sector generated, then the drive are far from simple than can not store the data, this will lead to the hard disk simply can not be used. At this point DiskEdit in the Pctools9.0 tools available to screen scrap the 0 sector, but instead of using a sector.
If the above ways will not work, you could use format procedures that comes with the motherboard or hard drive, such as low-DM, Lformat such a comprehensive low-level format the hard drive bad sectors.
