What to do when apt upgrade borks your system?

Rpi5 w penta data hat. Recognized the 2Tb drives fine. Did upgrade and now the system thinks they’re all 4Tb. Wish it were true. Things were fine on 3/25 but 4/3…

Wipe OS and start afresh?

Just burn yet another sd with system to reproduce issue, it should be ok and brake after upgrade if that caused issue.
