That's exactly what I meant.  Disk sectors developed what I can only
describe as "stuck bits".  You could write what you wanted, but you
could never read back exactly what you wrote unless you happened to
write those bits the way they were "stuck".

(Or, to look at it another way, random bits became unwriteable, but no
error was reported.)
