It is now 3 days since I started CHKDSK and is still on 51%. The current status is: 2CHKDSK is verifying Security descriptors (Stage 3 of 3). Repairing the security file record segment. 51 per cent complete (599226 of 132864 file SDS/SI processed). This final 3rd stage is taking awfully long. At the current rate it is going to take just undera year to finish!! I have read that once CHKDSK is started that it should not be stopped. But as you will appreciate a year is a long time to wait. Any advice would be greatly welcomed.
