"A comprehensive list of failures that can cause a drive to fail would
be as long as your arm, and there's really no point in compiling one.
This short list will give you a flavor for the types of failures that
occur:
Mechanical Failures: These include component failures related to the
mechanics of the disk. Problems of this type usually relate to the
spindle motor or bearings, such as motor burnout, "stuck" bearings,
excessive heat, or excessive noise and vibration. Actuator problems
would also fit into this general category. Unsurprisingly, mechanical
failures of hard disks comprise a large percentage of total problems.
Head and Head Assembly Failures: The infamous head crash fits in here,
as do other problems related to the heads: improper flying height,
head contamination, defects in head manufacture, excessive errors on
reads or writes, bad wiring between the heads and the logic board.
These too comprise a large percentage of total failures.
Media Failure: This class of problems relates to trouble with the
platters and the magnetic media, formatting, servo operation and the
like. This would include drives that fail due to read or write errors,
poor handling, scratches on the media surface, errors in low-level
formatting, etc. They are relatively uncommon.
Logic Board or Firmware Failures: These are problems related to the
drive's integrated logic board, its chips and other components, and
the software routines (firmware) that runs it. Again, problems in this
area of the disk are fairly uncommon compared to the other

categories."
