If I run chkdsk /f at the command prompt it finds problems but can't fix them because it can't lock the drive. I tell it to run at boot time but XP runs autochk not chkdsk at boot time. How can I setup the system to run chkdsk with the /f option at boot,(not at login). The scheduler doesn't work. It is a 11.7 Gig, FAT32 partition. Is there a way to create a boot disk to do this that will recognize the FAT32 partition?
