indicating multiple error events. Up to sixteen parameters are reported; each one
has a different parameter code, from zero to fifteen.
The error events are recorded in non-volatile memory and can be retrieved even
after the drive has been reset or power cycled. If more that sixteen different events
are recorded during the lifetime of the drive, then the oldest events will be
overwritten. The error events are ordered from newest to oldest with the newest
error event being the first parameter code.
