This method is used to exclude volumes from the chkdsk operation to be run at the next reboot. If not excluded, chkdsk is performed on the volume if the dirty bit has been set for the disk. Note that the calls to exclude volumes are not cumulative. That is, if a call is made to excluded some volumes, then the new list is not added to the list of ones that were already marked for exclusion, instead the new list of volumes overwrites the previous one. The method is applicable to only those volume instances that represent a physical disk in the machine and is not applicable to mapped logical drives.
