chkdsk problem


running plain chkdsk from cmd  reveals several errors that go uncorrected.
 I've discovered I can't run chkdsk /F while the system is running, and have said yes to the prompt that makes it run at boot up.  But at boot up it says there are no disk errors...even though running chkdsk from cmd again when the system is up reveals the same errors...

how can I fix these errors?  is there a 3rd party utility that will let me do it or how can I get chkdsk /F to work?

i don't think you have a disk error its moor likely chkdsk is trying to scan its own in use files and failing thats the reason it shod not be run on the c drive when windows is running the files in the prefetch folder may have got to big open the \WINDOWS\Prefetch folder and delete every thing in it for a nice speed increase at boot up i do this every 2/3 months

My system is in Spanish

>>>\WINDOWS\Prefetch\CHKDSK.EXE-2CC4C59D.pf  La primera unidad de asignación >>>no es válida. La entrada estará truncada.
translates something like this:
   \WINDOWS\Prefetch\CMD.EXE-087B4001.pf  The first  allocation unit is not valid.      The entry will be truncated.
   \WINDOWS\Prefetch\CHKDSK.EXE-2CC4C59D.pf The first  allocation unit is not valid.  The entry will be truncated.
