Use CHKDSK to Detect And Fix Hard Drive Errors Did you know that your hard drive is one of the very few mechanical computer parts? Unlike CPU and RAM that have electronic components, hard drives have a mechanical arm that moves whenever anything is written to the disk or read from the disk. That’s why it’s not surprising that your hard drive is the slowest part of your computer. But that’s not all – it’s also extremely prone to errors. These errors vary in severity and are caused by a number of things, from hardware faults and power cuts to interrupted data write process. Now, if any serious hardware faults occur, there is very little you can do. In fact, you would be better off backing up all your data, getting a new hard drive, wiping everything off the old one and chucking it into the bin.
The good news is that you have to do nothing of the sort in case of minor hard drive errors. Most of these errors are easily fixed with the help of a tool called Check Disk. Check Disk (CHKDSK) is a built-in Windows utility that can scan your hard drive for errors and bad sectors, repair logical errors, prevent further deterioration by moving data to the healthier parts of the disk and make sure new data is not saved to the bad sectors. This way Check Disk can improve the stability of your PC.
Generally speaking, it’s good to run Check Disk on a regular basis, like once a month. How to run CHKDSK (Check Disk) Running Check Disk is really easy even though the scan can take a long time to complete.
So make sure you don’t need to use your computer for something like 30-40 minutes (though sometimes it may take up to 2 hours), as Check Disk needs exclusive access to your system. Basically, the larger your disk, the longer Check Disk will need to complete the scan. That’s why it’s good to schedule Check Disk to run either at night or when you’re out. Or at least get yourself a large mug of coffee, sit back and relax. The process of running Check Disk is the same for all Windows versions, which makes things a lot easier.
You can launch the tool in two ways – from (My) Computer or from the Command Prompt. Here is how it’s done from (My) Computer.
