Does scandisk/CHKDSK produce a log file when running before login?



As an IT administrator, it's important to know whether or not running the Scandisk/CHKDSK command will produce a log file. This command is used to scan your hard drive for errors, and it's important to have a record of the scan results in case you discover any issues.

In short, the answer is yes, Scandisk/CHKDSK will produce a log file when it is run. The log file will contain information about any errors that were found during the scan, as well as any changes that were made to the hard drive. The log file is stored in the root of the drive, and it will be named CHKDSK.LOG.

However, there are some caveats to be aware of when running Scandisk/CHKDSK. First, the scan can only be run before the operating system has fully loaded. This means that if you're running the scan from within Windows, it won't be able to scan the whole hard drive. In this case, you'll need to restart your computer and run the scan from the command prompt before booting into Windows.

Second, if you're running Scandisk/CHKDSK on an external hard drive, you'll need to make sure that the drive is connected and the computer is powered on before running the scan. Otherwise, Scandisk/CHKDSK won't be able to access the hard drive, and no log file will be produced.

Finally, even if a log file is created, it won't necessarily contain all the information you need. In some cases, the log file may simply indicate that errors were found, without giving any details about what those errors were. To get more detailed information about the errors, you'll need to refer to the Event Viewer.

In conclusion, Scandisk/CHKDSK will produce a log file when it is run, provided that the scan is run before the operating system has fully loaded and the external hard drive is connected and powered on. However, the log file may not contain all the information you need, and you may need to refer to the Event Viewer for more detailed information about any errors that were found.
