Detection and repair of bad track in computer hard disk

Computer hard drive bad way is the word that we often hear, then what is the hard drive bad way? What is the cause of the hard drive bad? How to detect hard drive bad way, how to repair hard drive bad way? Please read this article.

Computer hard disk used too long will appear a variety of problems, such as the speed of the hard disk is slower than before, and read the disk for a long time, and then error, or Windows prompts "cannot read or write files", a serious blue screen phenomenon. These are caused by the bad way. Hard drive bad road is due to the hard drive in addition to its own quality and aging reasons, but also partly due to improper use of the cause. Hard drive bad road divided into logical bad and physical bad road two kinds, the former is a soft bad road, usually for software operation or improper use of the resulting, the software can be repaired; the latter is a real physical bad way, it shows that your hard disk track has a physical damage, can only be resolved by changing the hard disk partition or sector usage.

How to detect if your hard drive has bad track

As a result of the previous detection of hard disk bad way most of the disk in pure DOS to detect, and now USB disk instead of floppy, so the floppy drive also disappeared from the computer. The following is the introduction of the Ghost XP installation disk with the efficiency of the large-capacity HDD detection and repair program.

Set the computer to a CD-ROM boot entry, and then the selection interface appears, select [9] hard disk memory detection repair tool, click Enter.

Click on the efficiency source HDD detection hotfix to enter the program interface.

The main application of this interface is the "hard disk comprehensive detection" option, when the scan to the bad, will be on the right side of the "known bad track Information" displayed. The hard drive advanced detection option allows you to customize the start and end positions, but for most users it is appropriate to select the first item.

How to fix a known hard drive bad track

When you know that your hard drive is bad, do not panic, first of all, you should confirm that the hard drive is bad logic or physical bad way, the method is relatively simple, is still using just the Ghost CD to start, and then run [3]dos enhanced version and toolset, the implementation of the "ScanDisk", The ScanDisk program will check the hard drive, the resulting logical bad way will pop-up dialog box, select "Fix It" to the logical bad road for primary repair. If the scanner is stalled at a certain pace, then the hard drive has a physical bad way.

When detection is a logical bad way, we can try to use Windows with its own tools. Go to "My Computer" and choose a hard drive that has a bad logical path. Click the right mouse button, select the "Properties" → "tools" → "Start check" pop-up "ScanDisk", select "Full" and "Automatic Fix Errors" Tick, click "Start" to start scanning and repair the partition.

For the physical bad road, there are some trouble, if the hard drive can find a business solution, but if the hard drive can only be resolved. The most common solution is to use partition tools, such as Zoning magician, XP installed version of the partition tool, etc., through the hard disk repartition, hide the hard disk space, the physical bad road to the isolation.

Of course, sometimes, no matter how the isolation will detect the bad, then the method will only be low-level format. To know the low-level format is the last resort method, so I suggest users to use caution. Because the low lattice is to divide the blank disk from the cylinder and the track and the sector, the standard address and other information, will cause severe wear to the hard disk.

Low-level formatting can only be done in a DOS environment, after the Lformat command is run. Some bad tracks and bad sectors can be repaired by low-level formatting, but the physical scratches on the real hard disk's surface cannot be repaired, which means that the location of bad sectors is marked in a variety of ways so that the operating system does not use them.

Summary: The above to introduce some information about hard drive bad road, for some old hard disk, the probability of this problem is greater, I suggest to have physical bad way friends as far as possible to choose shielding method, do not have to lower their own hard disk, in addition to hard disk damage, the data inside is not recoverable.
