How to Automate ScanDisk and Disk Defragmenter Using Task Scheduler Tool

1. To configure ScanDisk, double-click My Computer, double-click Scheduled Tasks, and then double-click ScanDisk.
   
   NOTE: If ScanDisk is not listed as a scheduled task, see the following article in the Microsoft Knowledge Base for information about how to add a scheduled task:

2. In the Command Line box, type the following line

   <path> <drive>: /noninteractive /silent

   where <path> is the path to the Scandskw.exe file, and <drive> is the letter of the drive you want to scan. ScanDisk runs without user prompts if you use the /noninteractive parameter (switch). The /silent switch removes the summary screen.
   
   For example, you could type the following line:

   c:\windows\scandskw.exe c: /noninteractive /silent

Configure Disk Defragmenter

1. To configure Disk Defragmenter, double-click My Computer, double-click Scheduled Tasks, double-click Disk Defragmenter.
   
   NOTE: If Disk Defragmenter is not listed as a scheduled task, see the following article in the Microsoft Knowledge Base for information about how to add a scheduled task:

   178706 How to Schedule a Program Using Task Scheduler

2. In the Command Line box, type the following line

   <path> <drive>: /noprompt /q

   where <path> is the location of the Defrag.exe file, and <drive> is the letter of the drive you want to defragment. Disk Defragmenter runs without user prompts if you use the /noprompt switch. The /q switch defragments only the files.
   
   For example, you could type the following line:

   c:\windows\defrag.exe c: /noprompt /q
