From what I understood, the "freezer method" could work only in case of mechanical problems caused by wear. For example physical wear of the various hard drive bearings could lead to miss alignment of the read/write head and the tracks on the disk, therefore forcing the drive to operate at a lower temperature than "normal" tightens these bearings and reduces the miss alignment at least until the hard drive heats up again.
