Method of hard disk damage repair

1, hard disk damage test, if there part of the sector on the hard disk can not be properly read or write or visit the situation, the general was known as a bad fan (bad sector), which is commonly known as "bad sectors . "hard disk bad sectors is very complex, and some recorded in the sector by the checksum code, sector identification, address information, which do not normally lead to logical errors. Hard disk bad sector the situation is very complex, and some recorded in the sector by the checksum code, sector identification, address information, which do not normally lead to logical errors.
Such as certain viruses will force some hard-disk sector marked with bad blocks tag, so that system can not use these sectors. For example some viruses will force some hard-disk sector marked with marking of bad blocks, so that system can not use these sectors. Some of them are hit by the anomaly caused by a variety of reasons such as physical damage. Some of them are hit by the anomaly caused by a variety of reasons such as physical damage. When the hard disk bad sectors, it may appear hard to read and write errors or even slow down, sound anomalies, can not boot from the hard drive or can not be the completion of high-level formatting and other symptoms in severe cases will cause the entire hard disk can not be used to guide the system. When the hard disk bad sectors, it may appear hard to read and write errors or even slow down, sound anomalies, can not boot from the hard drive or can not complete the high-level formatting and other symptoms in severe cases will cause the entire hard disk can not be used to guide the system.

Hard disk bad sectors, the most simple way is to use the system detection built-in disk scan function, scan the disk in question and attempt to fix the bad sector. Hard disk bad sectors, the most simple way is to use the system detection built-in disk scan function, scan the disk in question and attempt to fix the bad sector. But its functions are extremely limited, and generally only handle some simple logic of sector errors, if you encounter really physical bad sectors, and its detection speed will be very slow. But its functions are extremely limited, and generally can only handle a few simple logical sector error, if the experience is really the physical bad sectors, it will be very slow inspection speed. At this point can be used for something more powerful detection software does not Scan the hard disk bad sectors, such as HDDTEST. At this point can be used for something more powerful detection software does not scan the hard disk bad sectors, such as HDDTEST.

HDDTEST is an extremely compact software, I use this version is only 8KB size. HDDTEST is an extremely compact software, I use this version is only 8KB size. But it can only be run in pure DOS environment, in the use of the former first copy it to a bootable system floppy disk, floppy disk and then starts .

Even brand new hard drive, in fact, is not without flaws, there is no bad sectors. Even brand new hard drive, in fact, is not without flaws, there is no bad sectors. In fact, each more or less hard disk in the production process, there will be a certain number of bad sectors. In fact, each more or less hard disk in the production process, there will be a certain number of bad sectors. While the manufacturers will use specialized equipment to detect all of the bad sectors and recorded in the P-Iist (permanent defects in the table), the average user can not be of the view, it can not access recorded in the P-Iist in bad sectors. The vendor will use specialized equipment to detect all of the bad sectors and recorded in the P-Iist (permanent one table) in the normal user can not be of the view, but also can not access the recorded in the P-Iist in bad sectors. In other words, the end-user's hard drive will be purchased with a certain number of bad sectors, but this part of the vendor with a special method of shielding has been lost, did not affect the normal use of the hard disk, which is not hard disk bad sectors so terrible as people might imagine. In other words, the end-user's hard drive will be purchased with a certain number of bad sectors, but this part of the vendor with a special method of shielding has been lost, did not affect the normal use of the hard disk, so people are not as hard disk bad sectors as you might imagine terrible. Generally speaking, if the bad sectors on the hard disk is not too serious, then, in addition to sending manufacturers rework, but also you can try some software to be repaired. In general, if the bad sectors on the hard disk is not too serious, then, in addition to sending manufacturers rework, but also you can try some software to repair it.

First of all, using some basic hard drive maintenance tools, such as the hard drive manufacturers DM software and low-level formatting tools Iformat so will be able to repair some of the logic of hard disk damage.
