That's a good idea.
Another application is if you suspect that part of the HD surface is bad
(old age, you dropped the HD, etc.) but the HD does not know it yet
because it has not accessed the damaged sectors yet. Then badblocks (or
dd) will force it to do so, probably bricking the HD in the process
(sometimes with audible clicking noises or such) which, if you think
about it, can be very useful if you intended to store valuable data on

Indeed, and that is true for thousands of CLI commands. ImageMagick
alone installs dozens which add complexity to your system if unused.
Back to the topic of HDs, I even remember seeing a unix program for
low-level formatting them, though formattable HDs probably have ceased
to be sold a long time ago.
