Keeping your hard drive free from errors is essential to the performance of your Windows 8 computer. When it comes to computer repair, this is one of the first things I do. So, if your experiencing problems opening an application or file, it may be time to check your hard drive for errors with Windows 8 built-in disk checking utility, CHKDSK (Check Disk).

There are two ways to run CHKDSK, standard, and advanced. Here are the procedures for both.

Standard hard drive error checking in Windows 8

1. Go to the Start menu.
   
2. Right-click the Start menu background to bring up the app commands.
3. Select 'All apps'.
4. Scroll to the 'File Explorer' tile and left-click on it.
5. Left-click on 'Computer'.
6. Right-click the hard drive that you want to check, and then click 'Properties'.
7. Click the 'Tools' tab, and then, under 'Error-checking', click 'Check Now'. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
8. Select 'Scan drive'.

Advanced hard drive error checking in Windows 8

1. Open a Command Prompt with Administrative privileges (click here for instructions)
2. Use the following command-line syntax(s) and parameter(s) to run CHKDSK:

CHKDSK [volume[[path]filename]]] [/F] [/V] [/R] [/X] [/I] [/C] [/L[:size]] [/B]
[/scan] [/spotfix]

The /I or /C switch reduces the amount of time required to run CHKDSK by skipping certain volume checks.

In this article, I am going to share my five favorite tips for maintaining Microsoft Windows.

1. Checkdisk. This is the first thing I do when I get a system here in the shop. Errors do occur, and files do get damaged. Best to take care of this first thing. And yes, this can take a while, so I always recommend leaving your system on and let Checkdisk run overnight. That way, your computer is ready to go first thing in the morning.
   

   For more information on how to perform a Checkdisk, select your operating system below:

   Windows 10 Checkdisk

   Windows 8.1 Checkdisk

   Windows 7 / Windows Vista Checkdisk

   Windows XP Checkdisk

2. Delete Temporary files. This is the first place to look when you need to free up some hard disk space. These files served their purpose at one time, but the program that used them did not delete them for some unknown reason. When deleting temporary files, some may still be in use. I recommend deleting all files/folders that are over a week old. See below for the location of the temporary files folder on your version of Windows:
   
   Windows Vista / 7 / 8.1 / 10 - C:\Users\username\AppData\Local\Temp
   Windows XP - C:\Documents and Settings\username\Local Settings\Temp
   
   
3. Delete the Internet Explorer cache. This is the second place to look when you need to free up some hard disk space. I have seen systems with over 9 Gb of temporary files. Open Internet Explorer and go to Tools > Internet Options and change the following settings:
   
   
   
   
   
4. Pagefile optimization. This one often gets overlooked. There is a formula for calculating the correct pagefile size. Minimum pagefile size is one and a half (1.5) x amount of memory. Maximum pagefile size is three (3) x minimum pagefile size. Say you have 4 Gb (4,096 Mb) of memory. 1.5 x 4,096 = 6,144 Mb would be the min. pagefile size and 3 x 6,144 = 18,432 Mb would be the max. pagefile size.
   
   
   

   To change the pagefile size, you need to access the System Properties dialog box. Press + Pause (Windows Vista / 7 / 8.1 / 10 users select 'Advanced' system settings). Then select the 'Advanced' tab and under 'Performance' click on Settings. Then select the 'Advanced' tab and under 'Virtual memory' click on Change.

   For more information on how to change the pagefile size, select your operating system below:

   Windows 10 Pagefile Settings

   Windows 8.1 Pagefile Settings

   Windows 7 Pagefile Settings

   Windows Vista Pagefile Settings

   Windows XP Pagefile Settings

5. Disk Defragmenter. Probably the best single thing you can do to speed up your computer. Imagine a filing cabinet where all of the folders were out of order, and files were misplaced throughout the cabinet. How could you find anything? Same thing with your hard drive. Disk Defragmenter takes care of that for you. And you can run it as a scheduled task too.
   

   For more information on how to use Disk Defragmenter, select your operating system below:

   Windows 10 Disk Defragmenter

   Windows 8.1 Disk Defragmenter

   Windows 7 Disk Defragmenter

   Windows Vista Disk Defragmenter

   Windows XP Disk Defragmenter

You can help solve some computer problems and improve your computer's performance by making sure that your hard disk has no errors.

Click on the Start button.

Click on Computer.

Right-click the hard disk drive that you want to check, and then click Properties.

Click the Tools tab, and then, under Error-checking, click Check Now. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

To automatically repair problems with files and folders that the scan detects, select Automatically fix file system errors. Otherwise, the disk check will report problems but not fix them.

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.

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.

Click Start.

Depending upon the size of your hard disk, this may take several minutes. For the best results, please don't use your computer for any other tasks while it's checking for errors.

Note:
If you select Automatically fix file system errors for a disk in use (for example, the partition that contains Windows), you'll be prompted to reschedule the disk check for the next time you restart your computer.

You can use the Error-checking tool to check for errors and bad sectors on your hard disk.

• Open My Computer, and then select the local disk you want to check.
• On the File menu, click Properties.
• On the Tools tab, under Error-checking, click Check Now.
• Under Check disk options, select the Scan for and attempt recovery of bad sectors checkbox.

Notes

• To open My Computer, double-click the My Computer icon on the desktop.
• All files must be closed for this process to run. If the volume is currently in use, a message box will appear, prompting you to indicate whether or not you want to reschedule the disk checking for the next time you restart your system. Then, the next time you restart your system, disk checking will run. Your volume will not be available to perform other tasks while this process is running.
• If your volume is formatted as NTFS, Windows automatically logs all file transactions, replaces bad clusters, and stores copies of crucial information for all NTFS volume files.
