You can use Disk Check in Windows 7 not only for local hard drives, but also for removable media such as USB memory sticks or memory cards. Disk Check can identify and automatically correct file system errors and make sure that you can continue to load and write data from the hard disk. You can troubleshoot the problem by using the Disk Check tool in Windows 7. This problem might occur because there are errors on your hard disk drive. Sometimes, your computer is noticeably slower or programs "hang" when you access certain files. Hopefully, Chkdsk will fix whatever hard drive problems you may have, and you can go back to using your computer normally.When you perform specific actions or open certain files, your computer crashes or programs freeze.

The chkdsk tool works pretty much the same in all versions of Windows. For that reason, you should always make sure you have a good backup routine in place and back up your PC before running chkdsk. If chkdsk does encounter problems-especially hard bad sectors-that it can’t repair, data can become unusable. RELATED: Bad Sectors Explained: Why Hard Drives Get Bad Sectors and What You Can Do About It Fortunately, chkdsk was able to recover the sectors in my case, and everything went back to normal afterward. After a lot of troubleshooting, a chkdsk scan revealed I had bad sectors where my Outlook data file was stored. That may all sound very technical, but don’t worry: you don’t need to understand the ins and outs of how it works to know when you should run it.įor example: I once had a problem where Outlook suddenly started crashing on me shortly after loading. Chkdsk attempts to fix these problems by repairing soft bad sectors, and marking hard bad sectors so they won’t be used again. Bad sectors come in two forms: soft bad sectors, that can occur when data is written badly, and hard bad sectors that can occur because of physical damage to the disk. Chkdsk can also optionally scan every sector on a disk volume looking for bad sectors.Such errors might include corrupt entries in a volume’s master file table (MFT), bad security descriptors associated with files, or even misaligned time stamp or file size information about individual files. Chkdsk’s basic function is to scan the integrity of the file system and file system metadata on a disk volume and fix any logical file system errors that it finds.Chkdsk performs a couple of functions, depending on how it’s run: It’s not a terribly exciting tool-and running it can take some time-but it can really help prevent bigger problems and loss of data in the long run. The Check Disk utility, also known as chkdsk (since that’s the command you use to run it) scans through your entire hard drive to find and fix problems.
