I have the same error with paragon HDM16, chkdsk does not solve it, there is no error in filesystem. Iam not able to make backup with ver.16. The same backup on the same pc with ver. 15 without problem. I reinstalled HDM and try to install on windows 7 pc - but cannot run it - mising some dll. Surprise is that there is only 5 activation with paragon hdm 16 licence ! So i lost any bacause of this error. I must go back and install ver 15, ver. 16 is unusable for me. I purchased it already - big mistake, lost money, lost fast whole day with testing and reinstalling , iam very sad.
