How to restore the broken sectors of a hard drive using HDD Regenerator

Starting to work with this utility, you can read a voluminous article about its work in order to roughly imagine the structure of the program: How to use Regenerator HDD. Plus, the utilities are that you do not have to create a boot flash drive or disk and go from under the BIOS.

The left button “Bootable USB Flash” will help you create a bootable flash drive to work with the program in the BIOS.
The right “bootable CD/DVD” creates a boot disk for the same purposes.
The upper line allows you to work from under the Windows axis, which saves time very much.

Click on the top line.

Choose your hard drive. It will write a model, the amount of memory and all sectors. Just click twice over it.

Please note that all windows should be closed, and all processes are stopped. Only then can you start working with sectors - the hard drive should be unloaded as much as possible.

Now you need a “Scan and Repair” item to confirm the intention to fix all sectors. Enter the number 1.
You can also enter the number 3 to activate the “Regenerate All Sectors” item. This option is preventing absolutely all sectors, even if they are not broken. This is more suitable for experienced users who can independently cope with possible problems in the regeneration process.

Now you have to choose the start of scanning:

The point under the number 1 “Start secretor 0” begins a scan and treatment from the very beginning.
The second version of “Start SecTOR ***” continues the past scan if it was interrupted for one reason or another.
And the third point “Set Start /End Sectors Manully” allows you to enter the range of sector checks manually.

It is better to start from the very beginning, choosing the first point.
