I have a toshiba laptop running winxp home edition. i went to defrag the drive since it has been awhile and i cleaned up some of the junk files. it tells me i need to run chkdsk/f so i say ok to do it on the restart. i then restart it does all the checking and says that it fixed something...i think it related to actual free room on the harddrive or something. then it starts up normal. i then click on defrag again and i get the same error. anyone have any thoughts or ideas to truly fix the problem so that i can run defrag. thanks in advance...
