My experience as I still use them is BAD BLOCKS are bad news (media dying)
or just a crunch from powering down with the disk in the drive. If the
disk does not erase and format without bad blocks it's trash here. I use
my CPM system to format 8" SD disks and failure is not common but in all
cases where I've seen that the media was shedding and gumming the head
so it's trash media and a head cleaning.
IF your trying to salvage data from a dying disk then you apply different
rules.
