Instead of stopping the process, why not view the Chkdsk log:
In XP, open the Control Panel, double click on "Adminstrative Tools", double click on the "Event Viewer" icon, then click on "Application". In the "Source" column, look for the "Winlogon" item. Double click it and you should see the results of your Chkdsk.
Hope this helps.

When I run CHKDSK on my Windows XP it goes through the whole procedure, steps 1,2,&3, then disappears real quick before I get a chance to read everything. Is there some way to keep it from doing that? Thanks
