I agree that the current display is more appropriate as a default.
But yes, I think adding a -vv flag to show the range output would be
useful. It seems interesting from an observability standpoint, since I
could easily tell how much damage did the file get. Simply telling the
number of checksum errors per file would be useful too, but not as
useful it was since each checksum error can be between 512 bytes and 128 KB.

Sure :)

Aren't USB pen drives great? (not!)
For curiosity sake, that "pen" pool is in a 2 GB partition inside a 4 GB
pen drive I bought recently, and both vmware-img.tar files have around
750 MB each.
The "ruben" pool is a *very flaky* 128 MB pen drive that a friend gave
to me since it was completely unusable with other filesystems.
For the record, in this filesystem, I set copies=3, filled the pool with
random files and even then the scrub found 1 permanent error!
