I'll say some specific parts of the magnetic platters of your drive are
damaged and that's why you get this error every time trying to access the same
files.

A drive has not to be old to fail; failure during the first weeks of activity
is relatively common.
It may have been badly packaged or handled during transport or may have been
badly manufactured ...
