start/run /cmd
enter 'chkdsk/f'
after finishing type d:
then again perform 'chkdsk/f'
perform this on every HD partitions.
This will dismount every partitions[except windows live] for full access to indexes nd for enuf authorisation for editing the indexes.
this shud solve the problem.
It seems that sthe chekdisk is unable to slove the error in read only mode.So u need to force dismount with /f
