I did my usual full backup (to an external USB disc) using 7.2.4156 with no problems and could open and read the backup using the Windows Explorer option.
I suppose the obvious problem may be a faulty sector on the USB disc giving a write error although I would have thought Macrium would have detected this and given an error message to that effect.
I would do a test on the USB disc to see if it finds any bad sectors.

I ran tests on my external drive, and no errors were detected.

My Macrium was updated to v7.2.4156 (UEFI), 64-bit. In the deep, dark corners of my mind, I seem to recall having had a problem with the 64-bit version of an earlier version of Macrium, so I'm going to uninstall Macrium and then install the 32-bit version. Wish me luck.

Any opinions about EaseUS Todo Backup Free, AOMEI Backupper, and Paragon backup software?

As usual, thank you very much, Pcqandaman and lenjack.
