11.3.2 MODE SENSE data

The MODE SENSE command provides a way for the drive to report its operating parameters to the initiator.

e drive maintains four sets of mode parameters:

1. Default values

Default values are hard-coded in the drive firmware stor

ed 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

changeable.
