[Tutor] Corrupt file(s) likelihood and prevention?

[boB Stepp]

I just finished reading a thread on the main list that got a little
testy.  The part that is piquing my interest was some discussion of
data files perhaps getting corrupted.  I have wondered about this off
and on.  First what is the likelihood nowadays of a file becoming
corrupted, and, second, what steps should one take to prevent/minimize
this from happening?  I notice that one of the applications I work
with at my job apparently uses checksums to detect when one of its
files gets modified from outside of the application.
