Continue by selecting Dos Programs .

In the Hiren's Boot main menu, select  Hard Disk Tools.

Step 2: Select More until you find the MHDD 4.6 function in Hiren's Boot. Usually, you need to select More twice , depending on the version you are using.

Step 3: The program will appear; select the drive you want to check --> press Enter --> press F4 twice to start the scan.

Step 4: The bottom section shows the percentage of the drive that has been scanned. The percentage of bad sectors is highlighted in dark red with a red X. Note that when cutting, you should add about 1-2% of the area you want to cut for greater safety.

To calculate the number of bad sectors, divide the total hard drive capacity by 100 and multiply by the percentage recovered during the scan to get the amount that needs to be removed.

Step 5: You must use DiskManager 9.57 in Hiren's Boot to remove bad sectors. Disk Manager (DM) is used to partition the hard drive to run the program . You can find it in DOS on the Hiren's Boot CD.

When you run it, a window will appear. Select Advanced Options --> select Yes. If the Select a Partitions Option window appears , select the bottom option, Define your own , and begin the disk partitioning process.

Step 6: The Disk Manager program will ask you to enter the size of the Primary partition ; the rest will be the Extended partition . Use Tab to switch to the Extended partition , then press the N key to subdivide this partition into Logical partitions .

Step 7 : To remove bad sectors, select the logical partitions containing the bad sectors, click Delete to disable them, and Save and Continue to apply the changes to the hard drive partition.
