Hard drive bad Track processing example

As a storage device of the hard disk, the probability of failure is not large, the normal use of the hard disk, if not affected by external forces, generally will not be a problem, and we saw some such as hard disk circuit board burned hardware failure, but also because of the user's very operation caused. But in the maintenance work of the computer, hard drive bad road is often encountered hard disk failure, most of the fault is the surface of the disk appears bad. This part of the hard disk circuit boards are good, in the Power-on CMOS settings, disk parameters can be detected, if discarded these hard drives, is quite a pity. In fact, a bad word usually appears in the starting area of the hard disk. Through the PowerQuest zoning software PARTITIONMAGICD processing, through the appropriate adjustment zoning, bypassing these bad, reduce some capacity, in addition to distribution in the vicinity of the bad road space is not available, these hard drives are completely normal to use.

Usually, we can fix the "bad hard drive" in several cases: first, the boot error, can not start normally. This is not necessarily "bad", usually with the MBR removed and 70% better to repartition. Second, can be normal partition, can be formatted, but the scan found that there is a "B" marked, that is, usually called "out of the bad way." There is no "physical bad way" or "Bad Logic", "B" a small number of words (less than 100), basically 80% can be fixed as a "good hard drive." Three is not normal partition, or partition after the format can not. This situation to use professional maintenance software, depending on the brand, repair rate is different. Generally reached about 50%.

In addition, some hard disk damage is serious, bad sector too much (some disk can not exceed 3000, some can not exceed 8000, some but allow more than 10000), the solution is to remove the problem of the head, or reduce the capacity, while changing the model, also is a usable "good hard drive." This can greatly improve the repair rate!

So what's the difference between a "good hard drive" and a hard drive that hasn't been repaired? Answer Yue: To the user feel no any difference, the professional person does not see the difference! Because use is the factory technology to repair, factory technician also may not see the difference lies!

A Pentium4 machine, the use of 80GB hard drive, start Windows XP system, has been stuck in the start screen, hard drive constantly "ka" rang, apparently hard drive out of the problem. This hard drive is divided into C (20GB), D (30GB), E (30GB) three partition, where C disk is system and application software, D and E disk is user data. According to this situation, it can be judged that the system is located in the C disk has a bad way.

Remove the hard drive, as from the disk to another in the C disk equipped with PartitionMagic 4.0 partition software on the machine, run PartitionMagic, select Disk 2, the first partition capacity in the starting position of 1GB reduction (can be much less, according to the needs and actual situation estimates!), The rest is unchanged; Confirm apply, the program after a part of Windows to do some work, restart the system, in DOS to do the rest of the work; If you need a dialog box to run the disk Character Map (Drive map), choose not to do it! Shut down the system, remove the hard drive, and take it as the main disk, Back to the original machine, found that the Windows system started normal, after entering the system, the application is working properly, this hard drive can work properly.

A Pentium 4 machine, using a 120G hard drive, the symptom is almost the same as above, the hard disk is divided into C (20GB), D (20GB), E (40GB) and F (40GB) four partition, where C disk is the system and application software, the other partitions are set on the extended partition, because of the last experience, So just follow these steps. Select Disk 2, found in the first section of the check failure, the first partition capacity in the starting position to reduce 1GB, confirm apply, start moving the partition data, in the 45% or so, appear "in * * * address error, cannot continue" dialog box, The program cannot be run again.

The author began to wonder whether the data in the bad lane affected the mobile partition? First partition to delete, delete, rerun PartitionMagic, at the beginning to reduce some capacity, reduce 3GB (more discard some space!), the remaining space established as the main guide area, confirmed apply, in the 45%, and then appear "in the * * * address error, Unable to continue the dialog box.

Is there any other way? This is most likely a problem with the boot sector of the hard drive, which may be the primary boot partition at the beginning. It's possible! Delete the first partition, empty 20GB on the tail of the F disk, and empty the extended F partition in the corresponding position 20GB. Set up a primary boot partition for this empty 20GB space and set it to active! Then PartitionMagic handled it smoothly, no more error messages. Note that this hard drive back to the original machine, in the rear of the new main boot partition of the disk is still a C disk, format, reload system and other software, all normal.

Because there are a lot of data and files in the hard disk, although the hard drive appears bad, we can be used to repair the normal use, but the emergence of bad way, it also means that your hard disk life will not be too long, so usually to do the backup of important files, hard disk price data is priceless, when the hard disk is really unable to repair, It will not result in the loss of important file data.
