Thanks a lot for that! Maybe it's not hardware after all :)
Please run SFC one more time to check for a progression (if more errors have developed since your first post, we have a problem, if the number is static, maybe we don't). [don't worry, I'll do the count, just explaining why I want it re-run]
Then download SFCFix from here: https://www.sysnative.com/forums/downloads/sfcfix/
run it (takes ~15 minutes), then copy and paste the logfile generated on completion here.
