The Problem

With the bootable USB drive ready, John shut down his computer and plugged in the USB drive. He then restarted his computer and entered the BIOS settings (usually by pressing F2, F12, or Del). He set the USB drive as the first boot device and saved the changes. He then exited the BIOS settings, and his computer restarted.

3. Multiple Passes

Sometimes a single pass doesn’t fix all sectors. Run the tool 2–3 times. Often, a sector marked “unrepaired” on the first pass gets fixed on the second.

Phase 4: What to Expect

• "Regenerated": If the software successfully repairs a sector, it will mark it as regenerated.
• "Delayed": If the software encounters a sector that takes too long to read, it may mark it as "Delayed." If there are too many delays, the drive may be physically failing beyond software repair.
• Post-Scan: Once finished, remove the USB and restart the computer to see if the drive is now accessible.

• You have a mechanical hard drive (not SSD).
• The drive is still detected in BIOS.
• There are no severe mechanical noises.
• You’ve already backed up your critical data.
• You have time (process can take over 12 hours).

By following these steps, you can create a bootable USB drive with HDD Regenerator and use it to repair bad sectors on your hard drive. Remember to always backup your data and use the tool with caution.
