My experience is that a few drives have a small number of bad blocks
remapped but continue to work. Most just keep
generating more bad blocks and soon stop working, so you want to copy of
the data ASAP.
I'd probably change that from "most" to "all" without much
concern. And
also "small number" to just "a number of tracks"--given the size of
drives
today, the badblock reserve isn't all that small. Which means bad block
checks on a newish drive should never report anything.
In fact, if they ever do, it means all the reserved blocks are exhausted.
This can, and usually does, mean they're failing at a significant, and
likely accelerating, rate. Essentially, once you *start* detecting bad
blocks, it's time to replace that drive, and sooner rather than later.
