He has been running video game servers from home for more than 10 years using Windows, Ubuntu, or Raspberry Pi OS. Nick's love of tinkering with computers extends beyond work. In college, Nick made extensive use of Fortran while pursuing a physics degree. Before How-To Geek, he used Python and C++ as a freelance programmer. He has been using computers for 20 years - tinkering with everything from the UI to the Windows registry to device firmware. Nick Lewis is a staff writer for How-To Geek. 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. Even if you're just having strange problems with apps not loading or crashing that you haven't been able to resolve another way, you might consider checking the disk.įor example: I once had a problem where Outlook suddenly started crashing on me shortly after loading. Sometimes Windows will automatically run a scan during startup, but most often you'll have to do it yourself. You should also consider running it any time Windows has shut down abnormally-such as after a power loss or system crash. You may want to run chkdsk every few months as part of routine maintenance along with using a S.M.A.R.T. 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. 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, which can occur when data is written badly, and hard bad sectors, which 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.
