10 best programs to fix a damaged hard drive

Among the various disasters that can happen to a PC, one of the worst is hard drive failure. Not only because we can (and do) lose the stored data, but also because in the worst case scenario we have to buy a new hard drive, disassemble the computer and replace it.

Sometimes it is not even necessary that our PC’s hard drive or SSD is damaged or defective. It is enough to have used it for a while for it to gradually slow down.

Top 10 Tools to Diagnose and Repair a Defective or Failed Hard Drive

One of the good things about Windows is that it has an internal utility that we can use to check and repair errors on the hard drive. This is the famous CheckDisk or “chkdsk” program for friends. For more information on usage, see THIS POST. Spoiler: You can also use the chkdsk command to repair external USB drives and thumb drives.

The downside of the Windows CheckDisk utility is that it lacks a graphical user interface, which means you need to know all of the commands and use them properly. Next, let’s review some free programs (all with a graphical interface, of course) that will help us troubleshoot PC hard drive errors.

CheckDiskGUI

As the name suggests, it is a graphical user interface (GUI) for the Windows command chkdsk.exe. The application weighs only 1.2MB and does not need to be installed to use it. Simply select the drive to be repaired and choose one of the 3 options available: Read, Repair, or Repair and Recover.

A very easy to use, free application that allows us to repair the hard drive with just a few clicks. In addition, once the process is complete, we can access a registry with all errors detected.

Defraggler

Defraggler is a free program for defragmenting your hard drive. One of its properties is the benefit of being able to Defragment the entire drive or just individual folders and files. It works with both conventional hard drives and solid state SSDs, with NTFS and FAT32 file systems.

Hard disk check (Puran software)

Another application that is very similar to CheckDiskGUI and essentially provides a graphical interface for the Windows tool chkdsk. This is a benefit as we make sure the program doesn’t do anything strange while it tries to repair the hard drive. Among its functions, you can repair multiple units with a single click, schedule scans for the next PC start-up (in case the hard drive is not recognized the first time), etc.

WinDirStat

WinDirStat is a free tool to help you see how your hard drive is organized. That means we can see at a glance how much the videos or certain files are taking up, and maybe it will help us to see that a large part of the hard drive is occupied by junk files or we don’t need it.

Essentially, it shows disk usage statistics on a map, with each file represented by a rectangle whose area is proportional to the size of the file. If sectors or files on the hard drive are damaged and a very large rectangle is displayed in WinDirStat, this may be the cause of the problem.
