Tried all standard methods including:
1] sfc/ scannow in Safe Mode [Fails @ 54% Verification with "W.R.P. Could Not Perform the Requested Operation”]
2] chkdsk /r

Do NOT want to use Windows Automatic Repair and risk losing many customizations etc.. Apologies in advance for waiting SO long to tackle this. I know it will make the problem harder to solve. Thanks, Mole.

After 5 months consider this request as redacted and transfered to another site - seems like long enough to wait.
