Tales of the Mortal World

To check whether the hard disk has bad sectors, you can use relevant tools and software to detect it, such as the "SCANDISK" disk scanning program that comes with the system. However, the scanning speed of this software is slow. It is recommended to use the "Efficiency Source Hard Disk Bad Sector Detection Software" to scan. "Efficiency Source Hard Drive Bad Sector Detection Software" can test various brands of hard drive products on the market. (1) Make a boot disk Run the downloaded program, insert a floppy disk into the floppy drive, and then run the program. Click the "Create Tool Disk" button in the main interface of the program to generate a tool disk for detecting bad sectors on the hard disk. Note: This software can only generate tool disks on floppy disks for the time being, so a floppy drive is required for use. (2) Detect hard disk Start the computer, press the Del key to enter the BIOS settings, set the "First Boot Device" option in "Advanced BIOS Features" to Floppy, change the first boot disk to the floppy drive, save the BIOS settings, and restart the computer. Then use the tool disk you just created to boot the system, and the program will be automatically executed after startup. If only one hard disk is installed in the system, position the cursor on the "Comprehensive Hard Drive Detection" option, and then press Enter to start a full scan of the hard disk. When the scan is completed, you can see the relevant bad sector information. If multiple hard disks are installed in the system, you can select the "Hard Disk Advanced Detection" option in the main interface. After entering the advanced detection screen, first enter "0" in the "Start Position", press Enter, then enter "100" in the "End Position", press Enter and enter the hard disk serial number to be tested in the "Current Hard Disk". For example, if you want to test the second hard disk, enter "2", and press Enter to start the test. 4. Repair hard disk logical bad sectors For hard disks, repairing logical bad sectors is relatively simple. When software detects bad sectors on the hard disk, the bad sectors must first be treated as logical bad sectors. If the bad sectors still exist, then the physical bad sectors can be repaired. (1) Repair hard disk logical bad sectors through disk scanner For logical bad sectors, the repair method is relatively simple. For users using Windows 98 system, you can click the "Start → Programs → Accessories → System Tools → ScanDisk" menu item, select the partition to be scanned in the dialog box that appears, select the "Complete" and "Automatically repair errors" options, and click the "Start" button. For users using Windows 2000/XP systems, you can double-click to open "My Computer", right-click the partition that needs to be repaired, select the "Properties" command, click the "Tools" button in the dialog box that appears, and click the "Start Check" button in the "Error Checking" option group. In the dialog box that appears, select the "Automatically repair file system errors" and "Scan and attempt to recover bad sectors" options, and click the "Start" button. Through the above methods, the problem of logical bad sectors of the hard disk can generally be solved. If you cannot enter Windows normally, you can use a boot floppy disk to start the computer, and then type "Scandisk X:" (X is the specific hard drive letter) at the prompt to scan and repair the hard drive. Once bad sectors are found, the program will prompt you whether to "Fixit". Select "Yes" and the repair will begin. (2) Repair hard drive logical bad sectors through DM Using the ScanDisk program that comes with Windows to repair the logical bad sectors of the hard disk will not harm the security of the data. However, the program's capabilities are limited. If you find that the hard disk still has bad sectors after repairing it through the ScanDisk program, you can consider using DM to repair it. Before using DM to repair hard drive bad sectors, you must first back up the data on the hard drive to other media. When DM repairs bad sectors, all data on the hard disk will be deleted, so the data must be backed up first. First download the DM universal version from the Internet and make a DM boot floppy disk, then execute DM and enter its main interface. Position the cursor to the "(M)aintenance Options" option, then press Enter. In the secondary interface that appears, position the cursor to the "(U)tilities" option. After pressing Enter, the system will ask you to select the hard drive that needs to be repaired. You can select it according to your own needs. Then press Enter to enter the secondary interface. Position the cursor to the "Zero Fill Drive" option. After pressing Enter, a red warning message will appear. After pressing the Alt+C key combination to confirm, select "Yes" to start "zero filling" of the hard disk. After completing the operation, just repartition the hard disk. This operation can not only repair most bad sectors of the hard drive, but also won't cause harm to the hard drive like low-level formatting. 5. Repair hard disk physical bad sectors For physical bad sectors, ordinary users cannot repair them at all. The only thing we can do is to use some disk software to divide them into a separate area and hide them so that the magnetic heads no longer read them. This can extend the service life of the hard disk to a certain extent. What needs special emphasis is that when using a hard drive with bad sectors, you must always back up your data, because after one bad sector appears on the hard drive, more bad sectors will follow. (1) Use Disk Genius to screen hard disk physical bad sectors After downloading Disk Genius from the Internet, make a system boot floppy disk according to the method described above, then decompress the downloaded compressed package, and copy the main program "Diskgen. Exe" of Disk Genius to the floppy disk. Of course, if a floppy disk is not available, the software can also be stored on a hard disk or other media. Use the floppy disk to start the computer, enter the "Diskgen" command at the prompt and press Enter to start the program. After entering the main interface of the program, press the Alt key to activate the function menu and select the "Tools → Hard Disk Surface Detection" menu command. At this time, the system will display the prompt "Test the current partition hard disk surface? The list of bad sectors will be saved in BACDSECT. TXT". Select "Scan" and press Enter. A scan method selection dialog box will appear. The scan methods are: scan by sector, scan by track and scan by cylinder. It is recommended to select the "by sector" option. After clicking the "By Sector" option to scan, the scanning process dialog box will appear. When bad sectors are scanned, a "click, click" sound will be made. After completion, a prompt message will appear indicating whether there are bad sectors and how many bad sectors there are in total. Restart Windows, back up all the data on the hard disk to other media, and then open the BACDSECT. TXT file in the floppy disk. Record the results of the scan just now in detail in this file. Record it with a pen. We will use this information in the following operations. Restart the computer with a floppy disk, enter the "Diskgen" command at the prompt and press Enter to enter the program's main interface. Press the Alt key to activate the function menu, and select the "Partition→Delete Partition" menu command to delete all original partitions. Then select the "Partition → New Partition" (or Create Extended Partition) menu command, and divide the 10 to 20MB space before and after the bad sector into a separate area based on the location of the bad sectors recorded in the BADSECT. TXT file (this is done to reserve some space for the spread of bad sectors). Note: If there is an error during the partition operation, the software provides a "reload" command to restore the hard disk to the initial partition state. Because all operations of this software before saving are only stored in memory, you can use multiple partitions to control the size of the partition containing bad sectors within a specified range. Finally, press the Alt key to activate the function menu, press the Tab key to select the partition containing bad sectors, and select the "Partition → Hide" menu command to hide the partition containing bad sectors. After dividing all partitions, save the settings and restart the computer. Finally, format all partitions through the Format command that comes with Windows. At this point, the work of blocking bad sectors is completed. (2) Repair bad tracks through "Efficiency Source Hard Drive Bad Track Repair Software" "Efficiency Source Hard Drive Bad Track Repair Software" can intelligently repair hard drive bad tracks. This software also requires making a bootable floppy disk before it can be used. Run the downloaded program, insert a floppy disk into the floppy drive, and then run the program. Click the "Create Tool Disk" button in the main interface of the program to generate a tool disk for detecting bad sectors on the hard disk. Use the floppy disk to start the computer, start the program, and select the "Intelligent Repair of Bad Sectors" option in the main interface to start repairing the bad sectors of the hard disk. When repairing bad sectors through this software, it is recommended to back up the data on the hard disk first, and use the software to conduct a comprehensive bad sector detection before repairing, and then repair it.
