every time i startup my computer it runs a check disk on the same partition. I have a 160gb drive and the partition that keeps getting checked is 60gb. then when i try to defrag the drive i get an error of "Diskeeper has detected that CHKDSK is scheduled to run on the volume: (E:. This is due to either a user request or because the oprating system has found errors in teh file system. CHKDSK will run automatically durint the next system reboot. until chkdsk is run, diskeeper cannot defragment this volume. any idea how to fix this with out formating the partition
