Mode Sense data

The Mode Sense command provides a way for the drive to report its operating parameters to the initiator. The
drive maintains four sets of mode parameters:
1. Default values
Default values are hard-coded in the drive firmware stored in flash E-PROM (nonvolatile memory) on the
drive's PCB. These default values can be changed only by downloading a complete set of new firmware
into the flash E-PROM. An initiator can request and receive from the drive a list of default values and use
those in a Mode Select command to set up new current and saved values, where the values are change-
able.
2. Saved values
Saved values are stored on the drive's media using a Mode Select command. Only parameter values that
are allowed to be changed can be changed by this method. Parameters in the saved values list that are not
changeable by the Mode Select command get their values from default values storage.
When power is applied to the drive, it takes saved values from the media and stores them as current val-
ues in volatile memory. It is not possible to change the current values (or the saved values) with a Mode
