e2label: Superblock checksum does not match superblock while trying to open /dev/sdb3 Couldn't find valid filesystem superblock.

I'm lost.
What does that mean?
How serious is it?
What may have caused this error is, I changed the name of the label of the drive from something like:"Linux Mint 19.3 Backups to Linux Backups. Oddly enough the Terminal is seeing the original name; while the software I used in Win10, where I changed the name, sees the new name. (Linux Backups)
Also, I re-partitioned the drive, from one h.u.g.e. partition to 5 separate ones. Home and Root are 100GB, with a good 78x.GB left over.
Hope this information helps...
