I really just wondered about the smart values, it's hard to find anything about what the values actually mean. Raw data of 1. Does that mean 1 block or sector? Current value of 199 and threshold of 140? After a total loss house fire, I'll probably use it and the other survivor for secondary backups from a hot swap bay and put them in a fireproof encasing. I had multiple backups and PC's. Out of 6 PC's with 2-4 HDD each, only 2 HDDs survived and a 120GB SSD. My thinking was always they aren't online at the same time and had plenty of backups in case one failed or ransomware. Never even thought about a fire. Both those that survived had no errors before. but do now. They got hot enough it burned the paper on the front. One said needed it needed formatted- data was gone and the other was just movies. Both show about the same error now. The one I had to format seems OK also.
