Sometimes, you may suddenly realize that your computer is running slowly. After checking the free space of your system partition as well as the others, you may get puzzled. Why is it running slowly? In this case, you may need to check your hard drive for bad sectors, the major cause of this issue.
So what is bad sector? According to Wikipedia, a bad sector is a sector on a computer’s disk drive or flash memory that is either inaccessible or unwriteable due to permanent damage, such as physical damage to the disk surface or failed flash memory transistors. If you leave it alone, you will find it too late to regret.
So today we are going to tell you how to find out these bad sectors.
Generally speaking, there are two ways to do this. And the first one is to use diskpart; the second one, of course the free HDD test utility. Both have their own advantages and disadvantages. Let’s see how does these two ways perform.
If you are accustomed with Windows Command Line, then the first way may suit you. All you need to do is the followings:
1. Run command prompt as administrator;
2. Input “chkdsk” or “chkdsk /f”, the later one will automatically fix the error it find.
However, if you are worried about the mistake you may make in cmd, you can try using a more straightforward toll called MiniTool Partition Wizard to help you. Launch this program and choose the disk or partition you want to check and select “Surface Test“. However, this tool only helps you find the bad sector but won’t fix it.
Many users have the doubt why not use the option “Automatically fix file system errors”? In fact, these are two different things. This one is used to fix the errors in files system. And you can access it by doing these:
1. Right-click the hard disk drive that you want to check, and then click Properties.
2. Click the Tools tab, and then, under Error-checking, click Check Now. In this step, a password many required for access.
3. Select Automatically fix file system errors to automatically repair problems with files and folders that the scan detects.
4. To perform a thorough disk check, select Scan for and attempt recovery of bad sectors. This scan attempts to find and repair physical errors on the hard disk itself, and it can take much longer to complete.
5. To check for both file errors and physical errors, select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors.
6. Click Start.
