EF5XX Data Retention Description,

Continued

After mounting, users’ requests from the host receive top
priority and are satisfied before restore requests. If a user
requests data that has not been restored yet, the EF5XX
fetches the data from the internal magnetic disk and returns
the data to the user.

Battery
Testing and
Monitoring

The battery subsystem (BSS) firmware logs a "Battery
Maintenance Error" under certain conditions. Table 5–1 lists
the type of error and why it occurs:

Table 5–1 Battery Maintenance Errors

Error

Reason

Battery failed periodic test.

The batteries undergo
a periodic trickle test
to check for shorted
cells.
