The Problem is that CHKDSK runs every time i start up,and sometime it asks while i'm still in windows.It only asks it for one drive ,my d drive,which is a ext. ntfs partion on my second hard drive which is for the swap files,scratch disc,other temp stuff.I have not asked this to be done,the only software i have installed is Diskkeepper 6(the defrag software),i think it has something to do with it because every time it runs a scheduled defrag,it asks to run CHKDSK while still in windows,however,when i try it says the drive is locked.Thanks for any help
