Thank you for your response, i usually do the f fix option because in the vast majority of cases that fixes it . I usually do repeat and rerun chkdsk because on the second try on many occasions it shows no problems but not always .
I run chkdsk and sfc/scannow on a regular basis in safe mode and i can't recall the last time anything showed during the sfc/scannow scan but sometimes i still get the chkdsk error , sometimes it says there's a problem with the bitmap image and sometimes it says the scan found free space marked as allocated .
Quite annoying , i do know that the system health report shows that it cannot tell if a AV product is installed although there always is one , i have re installed Kaspersky but it doesn't correct that issue . Don't know if it's related to the chkdsk problem
Thank you very much for the assistance
