Is it possible to remove BAD SECTORS on hard disk in order to make them reusable.
Removal for bad sectors in Hard Disk
Â
There is no hope of reusing a sector of the hard drive that is marked with a bad sector. Once a sector has been marked, the option of fixing it is impossible. But there are times where a sector that has been marked as bad can still be recovered and reused. But you will not have an assurance that your data will be safe if stored in a partially usable sector.
Â
Most of the time those bad sectors that have been recovered and reused eventually fail in an unpredictable amount of time. You wouldn’t know when will it gave in but eventually it will surely fail sooner. So, it’s your call if you want to gamble your data in the hard drive’s sectors with 50/50 health level.

Dear aqeel,
Actually as we face a problem of viruses and get ill because of some of the diseases.
Â
So same is the case with the system in a sense that they may becomes ill by facing some of the diseases and that disease is because of viruses and only the way to solve that problem is the little bit care and that care is that try to install always a good antivirus in your computer and do update s for it.
Â
And scan your computer at least once in a week it the best way to avoid the bad sectors in the hard disk drive.
Â
Thanks.

Hello Aqeel.
Â
YES. There is a way to remove bad sectors. Well, technically, bad sectors cannot be removed or made reusable again. However, by design, every hard drive has spare sectors. While reading data, the hard drive's firmware can actually detect these bad sectors and transfer the data from those bad sectors to a spare sector (in a process known as sector reallocation). If during a data write the firmware detects a problem on a certain sector, that problematic sector is deactivated and a spare sector is activated to replace the bad one.
Â
The best way to get the hard drive firmware to detect all and to reallocate those bad sectors is to do a Full Zero Fill (sometimes referred to as a "low-level format"). To perform a full zero fill, you have to download disk maintenance tools from the drive manufacturer.
Â
As an example, here is Seagate's tutorial on how to perform a zero fill on their hard drives:

I have done full zero fill on several hard drives already. Each zero-filled drive served me well for years without any problems.

Removal for bad sectors in Hard Disk
You can do a Disk Repair is logical bad sector removal and repair software that removes the logical bad sectors. This enables tracks the Bad disks as you run this software while on DOS operating system.
This will logically repair and restore all your documents back to their normal state of use. This is mostly done on the hard disk utility to repairs the bad sectors from Floppy disks using either FAT or NTFS definitely on Windows support.
