Apple is held in high regard for a number of things: branding, design, innovation and security. All these apply to their entire line of products. What cannot be denied, however, is that there is no device that runs flawlessly.
Even Apple’s high-end computers—the desktop workstation Mac Pro and the laptop MacBook Pro—can still run into problems that plague every hard drive-based computer. This article aims to help in the repair of one specific problem: bad sectors.
What are bad sectors?
These are parts of the hard drive that cannot be read or written on for new data. The data stored in those sectors either vanished or got corrupted.
Bad sectors also contribute to major slowdown of the computer even in simple processes. They can spread if they are still used, eventually destroying the entire hard disk.
What are the causes of this problem?
Hard drives are fragile pieces of equipment. It cannot take much impact or stand in high temperatures without getting damaged. When the disk inside the drive touches the head due to shock, it can lead to problems. Power outages that occur during data writing can also be a cause. Bad sectors caused by physical damage are called hard bad sectors, and they cannot be repaired.
Another cause of bad sector is the parity bits that got corrupted by malware, resulting in the data not matching when the hard drive is trying to read them. This is called a soft bad sector and fortunately, it can be repaired.
What can be done?
Mac users can rest easy with the help of these five professional programs that can repair soft bad sectors, and help make their Macs run smoother than before.
1. Disk Tools Pro
This all-in-one software can defrag the Mac’s hard drive once it starts slowing down due to excessive use. It alerts the user if a drive is in imminent danger of failing, and it creates a backup of entire volumes for worst case scenarios. They also repair bad sectors, among many other things.
What makes this software convenient is its ability to schedule any of the abovementioned activities without having to boot the damaged volumes with a CD.

Running into bad sectors on a Mac can be a frustrating experience especially when considering the stability of such computers, but it does not mean the end of their usefulness. Purchasing any of the aforementioned software can solve that seemingly irreparable problem, and they can even find a way to make the Macs faster and more secure.
Of course, it would be less expensive to simply keep the Mac from getting these problems in the first place. Here are a few tips:
- Place your computer in a sheltered place to keep it from getting hit or bumped.
- Ensure proper ventilation in the room to keep the hard disk from heating up.
- Make sure that enough voltage is provided to the Mac, especially when a lot of devices are connected to the power supply.
- Get a UPS (uninterruptable power supply), as it helps keep power surges and outages from damaging hard disks.
- Defrag the Mac at least every three months to keep data streamlined, so it wouldn’t have to work so hard locating files.
