Let's get the obvious out of the way, I messed up, bad. Over the weekend my daily machine (Mid 2012 3.33) started giving me beach balls every few seconds. Without thinking I did a NVRAM reset three times. Everything got crazy after that. Couldn't boot to Big Sur any longer. Removed all drives from the machine and put in an old Mojave backup and it booted fine. Thinking that I junked the EFI partition, I tried to mount it to take a look or get lucky with a rebless. It will NOT mount using Terminal, Clover, or OpenCore Configurator while booted into Mojave. Grabbed my daughter's Mini running Big Sur and plugged the bad BS drive in. The Data drive mounts and unmounts over and over. Again, cannot mount that EFI partition. At this point I believe the drive (Samsung 870 EVO) is possibly bad/damaged/corrupt which may have been causing the initial beachball issues.
I do have Time Machine backups. I'm not able to pull any of the data off BS drive in Mojave. Like everyone else, I got a million things to do and this wasn't one of them. I'm getting frustrated and not thinking straight. Should I get a new SSD and start over from scratch? Then restore Time Machine? I've honestly never used Time Machine, been lucky not to need it. Any help with what direction to go would be very appreciated!
One thing is for sure, I'll be documenting the process. I've been running this setup for three yrs without an issue (other than USB issues here n there) and I can't honestly remember how I got from Mojave to BS! Getting old sucks!
