Problem started with I/O errors on my Seagate 4TB internal hard drive while attempting a full image backup. chkdsk /f /r showed two bad clusters and after the extremely long /r a chkdsk on the drive showed no errors but encountered the same I/O error trying to do a full image backup with Macrium Reflect. Seatools for windows ran smart and short dst tests ok on the drive but failed with fix all and recommended Sea Tools for Dos which I booted and received a message stating No hard drives found but Windows 8.1 and Seatools for windows finds them all along with my recovery disk for Reflex.
Any suggestions appreciated
