Hard Disk Bad Track fault instance Solution

As a storage device's hard disk, the probability of failure is not high, normal use of the hard disk, if not affected by external forces, generally do not have problems, some hardware faults, such as hard disk circuit board burning, are also caused by user operations. However, in computer maintenance, Hard Disk Bad sectors often encounter hard disk faults, most of which are caused by bad sectors on the disk surface. This part of the hard disk circuit board is good, in the boot CMOS settings, the disk parameters can be detected, If you discard these hard disks, it is a pity. In fact, bad channels usually appear in the starting area of the hard disk. Through the processing of the PowerQuest partition software PartitionMagicd, we can adjust the partition appropriately to bypass these bad channels and reduce some capacity, except that the space distributed near the bad channels is unavailable, these hard disks are completely usable.

In general, there are several "Bad disks" that we can fix: first, boot fails and cannot be started properly. This situation may not be "bad". Generally, it is better to clear MBR and then repartition it. Second, the partition can be normally partitioned and formatted, but the scan finds that there is a "B" mark, which is commonly referred to as "bad track ". In this case, if the number of physical or logical channels is small and the number of "B" is small (less than 100), 80% can be fixed as "good hard disk ". Third, partitions cannot be normally partitioned, or formatted after partitions. In this case, professional maintenance software is used. The repair rate varies depending on the brand. Generally, it is about 50%.

In addition, some hard disks are seriously damaged, and there are too many bad sectors (some disks cannot exceed 3000, some cannot exceed 8000, and some can exceed 10000). The solution is to remove the problematic head, or reduce the capacity, and change the model, it is also a good hard disk available ". This greatly improves the repair rate!

So what is the difference between a repaired hard disk and an unrepaired hard disk? Answer: users do not feel any difference, and non-professionals do not! Because the factory technology is used for repair, the factory technician may not be able to see the difference!

A Pentium4 machine uses an 80 GB hard disk to start the Windows XP system. It remains on the boot screen and the hard disk keeps popping up. Obviously, the hard disk has a problem. The hard disk is divided into three disk partitions: C (20 GB), D (30 GB), and E (30 GB). disk C is the system and application software, and disk D and disk E are the user data. According to this situation, it can be determined that the drive C of the system has a bad track.

Detach the hard Disk from the Disk to another machine with PartitionMagic 4.0 partition software on drive C. Run PartitionMagic and select Disk 2; reduce the capacity of the first partition by 1 GB at the starting position (more or less, estimated based on requirements and actual conditions !), The rest remain unchanged. Confirm Apply. After the program finishes some work in Windows, restart the system and finish the remaining work in DOS; whether to run Drive Map) in the dialog box, select do not do! Shut down the system, unload the hard disk, take it as the main disk, and connect it back to the original machine. It is found that the Windows system is started normally. after entering the system, the application runs properly and the hard disk works properly.
