But let's start with SAFETY FIRST.
Be sure you have nothing you can't lose on this drive BEFORE attempting of the repairs you read about in the many other discussions.

<span id="INSERTION_MARKER">When I try to run disk defragmenter a window comes up and says, 'Disk Defragmenter has detected that Chkdsk is scheduled to run on the volume (C). Please run Chkdsk/f. I run Chkdsk/f from the run window the pop up window says, Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? Y/N I type Y and restart the computer. Upon restart I get the blue screen error mussage stating that: One of your disk needs to be checked for consistecy. It is strongly recommend that you check your disk.
Disk checking has been cancelled.
I have been reading forums and trying all sorts of things, nothing seems to be working.
