how to force CHKDSK on all local drives?
in [Windows XP]

From: someone watching on 4 May 2010 08:41 John, very interesting and informative post! I knew disks were checked when the 'dirty bit' was set but didn't know how to set it. Also didn't know only chkdsk could UNset it! This technique will come in handy when away for a day and want all volumes scanned. There is a question there however; being I'd like SURFACE SCAN (chkdsk /f /R), how can one have surface scan automated at startup? Does the registry have a entry for changing chkdsk defaults? Regarding entering chkdsk in a cmd window for each volume and following the prompts; great idea, have tried it and it works well albeit I did not try with /R switch (only /F). Lastly, pretty neat with the BootExecute registry trick! It's an option I'll keep in mind (in fact I've already saved your post for future reference). For what I'm wanting to do it looks like seeting the dirty bit would be the fastest and easiest method, provided chkdsk will automatically start (and run) with the /R switch ... so if you know how to have chkdsk start with a dirty bit with the /R switch, please let me know. Many thanks!

There are no user configurable settings for the way chkdsk runs on dirty volumes, this is coded within the operating system and it can't be changed. You can use the /r switch with user scheduled chkdsk, no need to use the /f switch with the /r switch, /r implies /f. By the way, none of my business, but running chkdsk as a preventive maintenance routine on NTFS volumes is for most parts completely unnecessary, NTFS is self healing and the operating system constantly verifies and corrects any files system or disk errors without user knowledge or intervention. Chkdsk can be run if you suspect errors or problems but otherwise you can run for *years* without ever running a chkdsk and this would in no way put your machine at greater risk than one where chkdsk was regularly run. Also keep in mind that there is *always* a risk of data loss when chkdsk is run, your backups should be up to date before you run chkdsk! John

If you are using the /f parameter chkdsk won't run on the OS partition but will offer to run on the next boot. As John has pointed out it's very seldom necessary to run chkdsk on NTFS volumes. I'd run a low-level disk diagnostic tool, such as SMART if your bios supports it, if I were really concerned about surface scan. Bill
