What is Chkdsk

A chkdsk is an MS-DOS program that you can use in order to fix how your files are being stored on your hard drive. It is used to check the status of a disk or hard drive, find and fix some errors, as well as display a report displaying the errors found on the location. Chkdsk displays warning messages whenever there are errors found on your disk.

The chkdsk is an external DOS command. This means that it is not loaded into the memory with the other DOS. Instead, it remains on the disk, and it is designed this way in order to reserve the computer's memory. Chkdsk is an abbreviation for "Check Disk."

This command may be used on your disk or hard drive. It checks the validity of a drive, the volume information, number of files, amount of free space on the drive and the total disk space. It will also provide you with the information in connection to the format of the disk, and your available RAM.

Whenever trying to run Chkdsk, there are some tips and reminders to be noted.
1. Do not run Chkdsk when still in Windows or in DOS window. You should first exit and run it on the DOS prompt only.
2. Chkdsk requires sole access to a volume whenever it is run. Do not open one or more files that you want your disk to check. If one or more files are open, it will generate the note on the next reminder.
3. In the Command prompt, if you already ran Chkdsk, and it generates the message "Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)", just type in Y, and then Enter. You can run the Chkdsk by restarting your computer.
4. If possible, do not run Chkdsk in read-only. This sometimes creates inaccurate reports
5. Chkdsk could take a long time to run. The time will depend on the number of files and folders, the size of the volume, disk performance and available resources. The resources include the processor and memory.
6. You cannot run Chkdsk as a regular user. You can only run this if you have Administrator rights.
7. The Chkdsk command can only be run under Microsoft Windows operating system.
