It looks like every Macrium Reflect backup (incrementals and full *.mrimg files) I have on my external back drive is corrupted. This corruption occurred just in time for Microsoft to auto upgrade my PC to Windows 11 (from Win 10 pro) without my permission, which screwed my hard disk completely.  So now I have no good backups and no bootable hard drive in my PC. 

Is there any way to salvage any of these MRIMG files? I tried running verify, and it found a large number of 'corrupt' sections which is then 'repaired' but I cancelled the repair expecting that the verification would utimately fail.

Any chance that all these repairs during Verification will work? What if they do not?
