Hmm, frustrating. I use Hitachi/Toshiba disks (to 2Tb) and have had no problems.
FWIW, I can confirm that having both Aomei Backupper Pro and Macrium free installed causes no problems, but I don't have them running simultaneously.
You could, for what it's worth, check SMART params and do a surface test with Crystal Diskinfo and Macrorit Disk scanner just to eliminate the most basic possibility.
