Luo Ji bad way:
Generally speaking, it can be found and repaired with the tools that come with the operating system and some special hard disk checking tools. For example, Scandisk, which comes with Windows, is the most commonly used tool to find the logical bad track of hard disk, but the Format command we commonly use can't repair any bad track of hard disk, which we should understand. In the Windows system environment, we can select the hard drive letter to be processed in My Computer, select its properties, select the error checking status in the tool button that appears, then select the full check in the scanning type, check "Automatically fix errors", and then start. If the system doesn't scan the disk or can't enter the Windows system when starting, we can also start the computer with floppy disk or CD-ROM startup disk, run Scandisk *: under the corresponding drive letter, such as "A": (Note: * is the drive letter of the hard disk to be scanned), and then press enter to repair the corresponding hard disk partition that needs scanning and repair.
Physical bad track:
Isolation measures should be taken to minimize losses and prevent further spread of bad tracks. If not, the final result is that the whole hard disk is scrapped. I don't think you want this to happen! *^_^*
Ok, I'll introduce you to one or two useful softwares.
Method 1: use FDISK to format the command format.
Here's the method. First of all, we should find out the capacity of the hard disk. For the problematic disk, it should be divided into C disks with FDISK, and then formatted with FORMAT. When we encounter an irreparable bad block, we always try to repair it and then record the percentage. Then press CTRL+BREAK to terminate the task, and use the total disk capacity × percentage to get the normal disk capacity. Then we can draw a logical disk with FIDSK, and then estimate the approximate size of the bad track for the following disk. This small disk does not need to be formatted. Delete after the overall work is completed, so that all bad blocks are skipped. This may lose some good tracks, but for large-capacity hard disks, it is insignificant and more stable to use.
Method 1: Use disk software such as PartitionMagic to complete the work.
For example, PartitionMagic partition software uses the "Check" command in PartitionMagic4 or the disk scanner in Windows to scan the disk and calculate the location of the bad cluster on the hard disk, and then select "Advanced /badSectorRetest" under the operation menu to divide the hard disk where the bad cluster is located into multiple areas, and then hide the partition where the bad cluster is located to avoid misoperation in Windows. This function is realized through the HidePartition menu item. This can also ensure the normal use of hard disks with serious bad tracks, and prevent the system from reading and writing bad tracks frequently to expand the bad track area. But this requires familiarity with these softwares and experience in calculating hard disks, which is not easy for many people to be accurate.
I think it should be enough to solve the problem! ! I hope you can understand.
